Reyes Audio Output Tamer

benjammin420 · 08-06-2010, 08:19 AM

This little guy came today in the mail, I hooked it up right away and started rocking. I was immediately impressed by how killer it sounds with my Class 5. Full blown tube saturation as bedroom levels, its just surreal. There are no negative effects on the tone of the amp as far as I can tell so far. The "Hi boost" doesn't make a huge difference, but does sound a bit nicer (according to the manual, the more you increase the output, the less effect the boost has)

You can see in the picture that the output level is pretty low, with the amps volume at max, that is the safe practice level. The gain is so juicy, I couldnt put my guitars down. Ill put up some clips when I get a chance

If you're looking for an attenuator for not too much money ($55) I would recommend this one. I dont have alot of attenuator experience to compare, but this thing has met my expectations and desires

Output Tamer - Attenuator Power Soak 16 ohm version on eBay.ca (item 290455568686 end time 17-Aug-10 16:35:43 EDT)

HOT TUBES 70 · 08-06-2010, 08:14 PM

very cool ! Thanks !!

MartyStrat54 · 08-06-2010, 08:22 PM

How did you hook this up to your Class 5? Did you actually put the output power into this, or is this just a "master volume?"

This looks like a different way to package what has been sold on EBAY.

If it is actually a "real" power attenuator for $55, that's great.

MartyStrat54 · 08-06-2010, 08:26 PM

Went to the site. Looks like it is a real 50 watt power attenuator for $55. Here is the listing info.

The OUTPUT TAMER is a handwired power attenuator to place between your amplifier's output and speaker. This effectively reduces your amplifier's output to more manageable volume levels. This attenuator also allows you to crank your power amp for full dynamics and saturation to achieve output tube distortion. I test these on my 50 watt amp at full gain and master volume to ensure reliability.

Function controls include an Attenuator Bypass switch and a Hi Boost with Bypass. This subtle hi-boost function helps to offset the tone degradation that occurs at low (maximum) attenuation levels. So far the reviews have been that the Output Tamer is one of the most "natural" sounding attenuators available today and users give it a thumbs up! I use audiophile grade components and audiophile grade 16 guage silver/copper wire with Teflon dielectric for purity of sound.

These versions are rated at 16 ohms and for amplifiers ranging from 1 - 50 watts maximum output. Please be aware that even though I test with my gain and master on maximum on my 50 watt guitar amplifier (Carvin x100b set at 1/2 power), some amplifiers can produce more power than stated so please use descretion when using your amplifier at full output. I offer a full refund / exchange / repair policy if your unit fails (or you don't like it) within 15 days. Beyond 15 days please contact me for options.

SOUNDS LIKE A DEAL.

It sits in between the amp and the speakers (I have a 1936 lead cab) I may even try to rig it up to run through the internal speaker, just for kicks, I like the tone of that 10"-er. I dont have much experience with attenuators, but so far this is exactly what I want out of one

This is a little blues jam, the lead track is my Les Paul (SD 59 neck and JB bridge) straight into the Class 5 (vol 9, treb 10, mid 8.5, bass 5) into the Output Tamer (same settings as the photo) into 2 G12T75 celestion speakers

I think that thing sounds great and the price is unreal. This little box would save me the trouble of taking my Power Brake off my 1987 when I want a little more volume than I can get with the "bedroom trick".

I'm curious about that heat warning printed on the front of it, though. How hot did this thing get with your Class 5?

No heat at all, the manual says to allow for a break in period before you run it full bore, but Ive had the amp cranked for hours at time, the amp is way hot, but the tamer is fine. The unit is rated for 50 watts, the C5 couldn't be more than 10w flat out.

I am very happy with this little box, I put the this same thread on a few different forums trying to spread the word, so far not much response (I guess my playing doesn't help much either

)

That's great to know. This thing just made my "Must Have" list.

Yeah, I saw your post over at the VM forum. I don't think it's your playing as much as some of those guys (maybe most of them) don't really have a grip on how to use them, never mind how handy a device like this can be and what a great find it is.

Keep us posted on your experiences with it.

I do think some people have weird, faulty preconceived notions about attenuators. I made a thread on the My Les Paul forum when I first bought the amp, and people scoffed when I said I wanted an attenuator, like I was a fool for buying an amp that "needed" an attenuator.

Micky · 08-09-2010, 06:14 PM

There are still a few cork-sniffers at MLP (here as well...) who feel that the tone will suffer if you use an attenuator. Ask about caps over there sometime...

Fact of the matter, anytime you do something to your amp, cabs, guitar, etc. your tone will be different. Notice I did not say worse...

Simply using a different volume setting will make things different. Purists will argue about anything it seems, especially if it is some sort of change. Personally I am glad to see someone doing something other than diming everything and letting the chips fall where they may. Good for you, it is info others here can use!

benjammin420 · 08-09-2010, 06:51 PM

Tell me about it. The other day I happened to mention (in a thread about Klusons vs Grovers) that I noticed some tonal differences between the stock Klusons on my LP with the set of Grovers I put on. Then this guy starts arguing, first, that there could be no differences, then after I and others got him to conceed it could possibly make a noticable difference, he starts to argue that it shouldnt matter, thats its corksniffing, blach blach. I never said it mattered, I just said "I noticed a difference between A and B"

back on subject, the only problem I have so far with the Tamer is that its making me want to experiment with different tubes and speakers haha

Micky · 08-09-2010, 08:31 PM

Benjamin there are plenty of aspects to this music stuff that it can have a special place for each and every one of us. Experimentation is key, even if you do call it 'searching for my unique tone'. For others it is vintage, collecting, performance, etc. but you know what I mean. Cork-sniffing is a lot like religion, feel free to worship whatever YOU want, but don't put ME into that mold.

To find what works for YOU and to do what you enjoy is key. I couldn't participate in anything I wasn't enjoying, so for me it is a passion to something I have never done before. I played in a cover band since the '70's and we made a ton of money back then. When it wasn't fun, I got out. Now I am back into Les Pauls and Marshalls, the combination to me is fascinating!

I played Teles and Fenders previously and I felt it was rather limiting. I could also never play as well as I always wanted to, and for me a nice guitar has opened that door to learning new stuff again.

An attenuator is next for me, and I will definitely build my own, so seeing what others are doing and using is valuable info. I hope others find your experiences just as useful as I do.

Heres another clip with my new strat (w/ Hot Noiseless pickups), thru a Keeley Fuzz Head (germanium mode, vol max, gain around 8 o'clock) into the Class 5 (same approx settings at the first clip)

13eastie · 08-25-2010, 08:25 AM

Ben, could you by any chance post the dimensions of the attenuator? It looks pretty small compared to the size of the 1/4" jacks.

Also, is it straightforward to dismantle, so that mounting holes can be drilled?

benjammin420 · 08-25-2010, 08:36 AM

its about 5.25" x 2" x 3"

real easy to take apart, 2 screws on the top, 2 on the bottom, this is what is inside

13eastie · 08-25-2010, 09:01 AM

Thanks, Ben - that's brilliant. I've got one on order to mount inside my Class 5.

el zilcho · 08-25-2010, 04:06 PM

Wait...so it's just an L-pad?

Eh...yup. Alright, the alarm bells are going off now. That explains why it's so cheap. I wonder how that rheostat maintains a constant load on the output transformer.

I know Weber uses speaker motors and THD uses resistors. A rheostat is technically a variable resistor. Wouldn't the impedance vary as you turn the dial? Nothing to dissipate the heat either but the box it's in. I bet you could fry an egg on that thing with a 50w amp plugged into it and cranked but I wouldn't try it because that looks like an output transformer cooker to me. Maybe Wilder or one of the other techs will take a peak and comment on the merits of that design.

MM54 · 08-25-2010, 04:44 PM

I still want to know why they've not come up with a 100W or even 150W version yet

el zilcho · 08-25-2010, 04:53 PM

Sorry guys, I edited my post too late.

It must be an L-pad, not a rheostat, in order to keep the load constant. I've just never seen an open L-pad like that.

MM54 · 08-25-2010, 05:00 PM

Oop, you're right el_z, I didn't see the third prong

Edited my post as well

If it's that simple, I might build one that can take more than 50W. You can get a 50W 8 ohm L-pad for like $10 anywhere, and I see Parts Express has a 100W one for like $13. I don't see why you couldn't put it in parallel with the output jack and that in series with two more parallel 8-ohm 50W power resistors and have a 200W box.

chuckharmonjr · 08-25-2010, 05:46 PM

L-Pad Attenuator just making a good ole fashion voltage divider trimpot..how cool and utterly simplistic, but I bet ya could fry an egg on it at a full 50w output.

el zilcho · 08-25-2010, 05:52 PM

If you put 2 L-pads in parallel, I think that you would lose a lot of your max attenuation because the resistance would decrease.

For a 100w amp you would definitely want something with at least a 200w rms rating. I don't think anyone makes an L-pad that big. But you could do the same thing with 2 big 25ohm resistors. It just wouldn't be variable. There was a DIY design out there that used a rheostat along with a pair of resitors for more flexibility. Search for 'airbrake attenuator'.

chuckharmonjr · 08-25-2010, 10:02 PM

Well EZ....if you put two 16 ohm L Pads in parallel...that would be 8 ohms reflected load back to the amp....just might work. Set the OT switch to 8 ohms you would be good to go. Also, two 8's...set the switch to 4 ohms output. Right? Why would it be different than 2 16ohm or 2 8ohm cabs in parallel?

chuckharmonjr · 08-25-2010, 11:26 PM

Impedance is the square root of the sum of the squares of resistance and reactance...so if you have 8 ohms reflected load whether it is 2 16 ohm cabs or 2 16 ohm rheostats....its the same difference.

el zilcho · 08-25-2010, 11:52 PM

I believe the ohm rating for L-pads doesn't have anything to do with their actual resistance (it's variable, after all). It think it has to do with the offset and relative taper of the two variable resistors that make up the L-pad.

For example, say it's an L-pad meant for a 16ohm load connected to a 16ohm speaker. The positive speaker wire is connected in series with the 1st variable resistor and the negative is connected in parallel with the second variable resistor. Let's say at a certain position both resistors are 25ohms. Using ohm's law this brings the total impedance to 15.53, which is pretty close to 16ohms.

If we used those same 25ohm values with an 8ohm speaker we would have 33ohms in parallel with 25ohms, giving us 14.224ohms. That's not even close to 8ohms which is why you need an L-pad which is designed for a specific load.

So you wouldn't want to use 2 16ohm L-pads in parallel on a 8ohm load. You could do it with a 16ohm load and be fine, the wattage handling would increase but the resistance and attenuation would be roughly halved. So...I dunno, that might or might not still give you enough attenuation...?

It's also completely possible that I am wrong about all of this.

I don't see why you couldn't put it in parallel with the output jack and that in series with two more parallel 8-ohm 50W power resistors and have a 200W box. __________________ -Matt If you don't understand what I'm saying, assume I'm making a joke.

For a 100w amp you would definitely want something with at least a 200w rms rating. I don't think anyone makes an L-pad that big. But you could do the same thing with 2 big 25ohm resistors. It just wouldn't be variable. There was a DIY design out there that used a rheostat along with a pair of resitors for more flexibility. Search for 'airbrake attenuator'.

Set the OT switch to 8 ohms you would be good to go. Also, two 8's...set the switch to 4 ohms output. Right? Why would it be different than 2 16ohm or 2 8ohm cabs in parallel? __________________ JCM2000 DSL100 JMD-1 100 Watter JMP800 2204 MG50DFX Vox AD30VT Valvestate 20 1960A 1960B MG412A Seismic Audio 2-12 Black Cherry Les Paul Tobacco Burst Les Paul Black Les Paul Custom Honey Burst Les Paul R8 Les Paul in Tea Burst ES-175 in Cherry EDS-1275 in White Fender Strat in Tobacco Burst Black Charvel Fusion "When it comes to electricity, make sure it's dead before it makes sure YOU ARE!"

el zilcho Member Join Date: Nov 2009 Posts: 85	Re: Reyes Audio Output Tamer I believe the ohm rating for L-pads doesn't have anything to do with their actual resistance (it's variable, after all). It think it has to do with the offset and relative taper of the two variable resistors that make up the L-pad. For example, say it's an L-pad meant for a 16ohm load connected to a 16ohm speaker. The positive speaker wire is connected in series with the 1st variable resistor and the negative is connected in parallel with the second variable resistor. Let's say at a certain position both resistors are 25ohms. Using ohm's law this brings the total impedance to 15.53, which is pretty close to 16ohms. If we used those same 25ohm values with an 8ohm speaker we would have 33ohms in parallel with 25ohms, giving us 14.224ohms. That's not even close to 8ohms which is why you need an L-pad which is designed for a specific load. So you wouldn't want to use 2 16ohm L-pads in parallel on a 8ohm load. You could do it with a 16ohm load and be fine, the wattage handling would increase but the resistance and attenuation would be roughly halved. So...I dunno, that might or might not still give you enough attenuation...? It's also completely possible that I am wrong about all of this.
