Re: Power tubes?? Who, What, When Where how??

No, I haven't ever tried them. You can still get Ei EL84's and they are real solid power tubes. I used to have the link as I have posted this info several time. Look on Google for AES. They have them in stock.

Re: Power tubes?? Who, What, When Where how??

Joe, I was doing some research and came across this thread from 2008. A guy is wanting to try some 6CA7EH's. If they have been around for this long, then I think the history of reliability is good for this tube. That's a plus. Here is the thread.

Re: Power tubes?? Who, What, When Where how??

Instead of spending $300+ for a matched quad (used), I think I may just buy four of these. Hell, I won't be out all that much if I don't like them.

They have solid track record.

Sheet...I got up too early. Gonna be drag'n ass later.

I think they would be worth a try. I sure like them so far. Also I want to hear you compare them to the real Fat Boyz and see where they stand.

On a side note I got the Tele's already. Haven't got to open the box up yet but I will get to roll'n very soon. Thanks Marty!

Re: Power tubes?? Who, What, When Where how??

Hi guys,

I stumbled on this thread today, as I am looking for some new valves for my TSL122.

Tons of good info here so thanks to all the posters for that. The question I have is, what about these Mullard EL34 "re-issue" ones? Are they any good? They are going for a quite low price on ebay, but are they worth it??? Any advice would be very much appreciated.

Also, as being quite new to Marshall, which valves (pre amp and power ones) would you guys recommend? Again any advice much appreciated.

Thanks in advance,

Peter

Get ready, cause here comes a big wave right at you!

Try the preamp thread too.
Preamp Tubes? - Who, What, When, Where, Why, and How?

I haven't tried the Mullard RI EL34's yet. Hear tell they are good sound wise. Don't know about reliability wise.

Re: Power tubes?? Who, What, When Where how??

Peter, I like the Groove Tubes GTEL34M Mullard reissue better than the Russian Mullard-branded tubes. I've used Electro Harmonix EL34s before, and they weren't bad. SED Winged Cs are good, too. I've not been happy with the JJs I've used but a lot of people like their E34L. I bought a set of them and left them in the amp when I sold it. I don't think that any of them can touch the RFT EL34s I'm using now, but they are NOS and will cost you around $200 for a matched quad.

If you read through the last few pages on the preamp thread, there's been a lot of good discussion lately. Tung-Sol reissues are good current-production tubes in a Marshall. The Ei ECC83s are good tubes and still pretty cheap, but sometimes they are microphonic in combo amps, but they would still make a good V3 or V4 tube. If you want to go old, spend most of your money on your V1 tube - I like the Philips tubes I have (Mullard, Telefunken), and RCAs, Raytheon black plates and GE 12AX7s are good USA tubes. If you find something you're interested in and want more info, just post it over in the preamp thread.

Re: Power tubes?? Who, What, When Where how??

Any of you guys ever tried the Matsushita EL34s? They seem to go for pretty cheap when they turn up. Anything at all to the Mullard hype around them? I've seen a couple that were printed "Made in Gt. Britain", and they supposedly used Mullard tooling. One review I found said they were "dry" sounding?!?!

Re: Power tubes?? Who, What, When Where how??

Hey guys.

Well I migrated over here because I am going to be in the market for some power tubes. NOS is right out for me so what are you guys liking in CP. I have read good things about the winged =c=, anyone have any experience with them?

I am currrently running Svetlana's which I found out are actually Sovtek, not real Svetlana's (I guess) and I am not happy with them. The GT's I had in my amp were even worse.

I would love to get set of RFT's but I can't justify the price tag.

Thanks guys

Re: Power tubes?? Who, What, When Where how??

Winged =C='s are a solid toob in a Marshall. Great reliability. I've described how they've sounded before so I'm not going to again hehe. Being lazy...

I prefer the 6CA7EH's.

So one vote for the winged =C= then.

What's the story on the 6CA7EH's? I am not familair with them other then they are a direct replacement for the EL34. Don't they have like more bottom end then the EL34 or something like that?

They remind me alot of like a JJ EL34L or the KT-77 in their range but to my ears sound better. More chimey in the highs. I can hear more string definition and articulation is great.

I just think they have a great frequency range and yes a big bottom is part of that. You never really know how a tube will do unless you just put them in and see. I will say the Winged =C='s won't be a wrong choice IMO.

The Ruby EL34BHT are getting real good reviews now. They are the newest version of the BSTR's. I will pick up a pair eventually and try them.

I always try tubes out in my amp so I have a real say in how the tube performs.

Re: Power tubes?? Who, What, When Where how??

Hi again all,

Thanks for the replies, I am a bit wiser again
I think I might give the Mullard re-issues a go as for a matched quad set
it is only £45 or $75, so can not go too wrong in the wallet there lol.
By the way, this is the description they give on ebay, maybe some of you can give even more info as to what or how, as like I said before, am relatively new to Marshall amps. And before anything, I have got nothing to do with the ebay seller lol

"Platinum Matched QUAD of MULLARD EL34 Power tubes 6CA7 / EL-34 NEW
TUBE INFO: These tubes are Brand NEW Genuine Re-issue MULLARD's from the New Sensor Corporation in New York. They are modeled after the original Mullard XF-4 and have all the sound you would expect from a tube with the Mullard name. Each tube comes in the original Mullard Retail Box with the readings from the factory recorded on each."

Re: Power tubes?? Who, What, When Where how??

Well, it's a little misleading. What's the difference between a tube store that does a 3 per cent match and a "platinum" match? Also, the ad makes it seem as if the tubes are made in New York. They are made at the Sovtek factory in Russia.

Other than that, I have recommended those tubes before. Post back and tell us how they sound and where you have them biased at.

Sorry for missing your question. Any tube made by Matsushita is a quality tube. I would love to be able to buy a dozen or so of their 12AX7's. The EL34's were made during the 60's and up until around 1977. They can be identified by a single seam at the top of the tube. Radio Shack sold a bunch of them, so if you find some EL34's labeled Radio Shack with a seam top, they're Matsushita's. Raytheon and Westinghouse in the early 70's would relabel Matsushita EL34's. They have a very solid reputation and rival the quality of a Mullard. Who was behind the Matsushita plant? It was set up by the big giant, Philips, the parent company of Mullard. The tubes were built on Mullard equipment. Sweet. When they are on EBAY, a pair of strong one's will fetch about $75 to $85. Online tube stores, $35 used and $65 new.

Yeah, Philips was in everybody's business by the early 70's.

I've been reading up on these 6CA7EH tubes. A lot of high gain players love them. They seem to have the best qualities of an EL34 and 6L6. I may have to try these out.

I found a test report on the Watford Valves website that covers a lot of the tubes we've been talking about. The reviews were done on Marshall lead and bass amps, and some high-end Radford monoblock amps. It's a PDF document, so you may need the Adobe Reader to view it.

Re: Power tubes?? Who, What, When Where how??

I got some real Philips 6CA7's and they are a really nice sounding tube. As described before, a nice fat bottom and very articulate in all registers. Nice top end with some sparkle. I am playing through a 602 with two Eminence Delta PRO 2 speakers. These are neutral, flat speakers. Actually one of the best non-guitar speakers for guitar. They are actually mid-bass drivers for PA systems. They have a flat frequency response from about 45Hz up to about 4.7KHz. What this means is that you can really hear the voice of the tubes.

I'm going to run the 6CA7's for about 30 days as I want to save the for my dream amp that I want to buy.

6CA7's huh?

Sounds interesting. Sounds almost what I would be looking for because I am a high gain player and I am looking to love something.

You say you are playing them Marty? What kind of style do you play? I thought I heard you mention you do some shredder type style and that is what I am into. Are those tubes clear and really articulate?

Well I guess at one time I thought I was a shredder. No, I play AC/DC, Nugent, 80's stuff was big with me. I like older Clapton. Nowadays, I like hot rod blues. This involves playing hot blues with a Marshall and not a Fender. My live gigging days are starting to dwindle, but I still make it out every once in a while.

I think the Electro-Harmonix 6CA7 is a tube worth looking into. A quad is reasonably priced, so your not out of a lot of dough. I love my Philips 6CA7's and I know Joe likes his 6CA7EH's. These may be the tubes you are looking for.

You are referring to the CP Electro-Harmonix correct?

They really do sound like what I would be after and they are in the price range. I may have to check them out.

You know what I wish you would have done? I wish that you would have looked in the organ for a date of manufacture. Those are Sylvania's. They have the green tube codes on the base. I'm thinking those could be 1959 tubes. They would have to be somewhat old, because the 6L6GA and GB were made a long time before the 6L6GC. In fact, the GA and GB have the same spec's as the original all metal 6L6. They can only take 360VDC on the plates.

I have access to the organ. I can go and check it for manfacture date. That's not a problem.

I will check on Monday.

Cool. On the amplifier, there should be a tube placement chart. Usually there is a date on this. It might not be the exact date, but it would be close. It is sometimes in small print. Also, there might be inspection stickers. These will have a very close date of manufacture on them.

Re: Power tubes?? Who, What, When Where how??

Hi Guys

Ive been a big reader of the pre amp version of this thread for the longest time, and got lots of great info from it, in fact im going to post in it in a few minutes asking about some black plate raythons i have found on ebay, but first this

EL84 PHILIPS MATCHED QUAD (4PCS) NOS BOXED on eBay (end time 05-Dec-09 10:55:16 GMT)

Are these the real deal, and if so why so cheap? Another thing is will they fit in my DSL 401 as i have read elsewhere that the holes in the chasis dont fit all tubes?

thanks

Spirit.

Hey Spirit. Those are not real Philips tubes. They are Russian and have been relabled as Philips. They were probably made in the late 80's, early 90's.

They probably are a pretty good sounding EL84. One of the other guys tried American Black Plates up against the Russian EL84's and he went with the Russian tubes. Of course, a lot depends on who and where they are made.

These are probably Sovtek tubes.

There are only a few current production tubes that are bigger that you don't want to use in your amp. It's all about how close the tubes are together and heat transfer.

Thanks for that, i have found some real phillips ones but they are more like £40 each, so thats why i had to ask. Bit cheeky that he is saying they are made in '67 though is it not?
