What do you think of JJ E34L tubes compare to ruby EL34BHT tubes
i am surprise no response...no one tried the EL34BHT Ruby?
I've tried the Ruby BSTR's but not the BHT however I hear that they are very similar sounding to each other. Anyways I've tried the the 34L's and the BSTR's in my DSL and I like the 34L's a little better due to the mids they have and the rolled back highs. I would use either and I have for what I play. I noticed a few players putting the BSTR's in high gain amps and really liking them. I'm not a high gain player. Hardrock is as high gain as I go or old school metal.
What you think'n?
i hear lots of people talking good about JJ but i have Ruby in my other amp... wondering if JJ are worth a try... or Ruby is better...
Well I like to just try them to see. I have a whole drawer full different brand EL34's from experimenting. I don't think Ruby BSTR's are better. Different yes. Its gonna boil down to what you prefer and depends on the amp they are going in. I like the mid character of the 34L's and the restrained highs more than the BSTR's character but thats a preference and judged solely in my DSL50. Neither of these are my favs although the 34L's are on the top of my list. I'm not a JJ fanboy either. I do not like the ECC83S's in any of my amps(Night Train, Monza or my DSL50). Just so you know I'm not trying to get you to go one way or the other.
JJ's aren't that expensive either(I only have to buy a pair)to experiment with. I don't think you can really say one way or the other until you try both in the same amp. Hell amps differ and so can the same tubes for that matter...
I'm interested to hear how you go when you choose though so give a report on how it turns out if you care to.
going to my tech friday night... we will try differences...
I've tried the JJ tubes and I'm not to keen on them. My brother got me four, RFT's for my DSL100 and I like them over any thing I have tried. Right now I am running the Winged C's in my 2204 and they sound way better than the JJ's.
Welcome to the forum!
I think this is where taste comes in and I was trying to convey that to kebek so he actually tries them. I have RFT's as well and thought they were good but I like the 6CA7EH's more. The tone suits me better. I don't like any other JJ tube other than the 34L's in my my DSL. Winged =C='s are just a great all arounder. Tone wise I think they are solid but durability wise is where I feel they really shine.
Nice amps by the way! A few of the guys here have the RFT's and luv em'. I have Winged =C='s, Tung Sol 34B's, JJ 34L's & KT-77's, Ruby BSTR's, RFT's and 6CA7's which I like the most tone/feel wise. Usually I'll ask or read up about certain tubes and then if I'm still interested I'll test them out to see for myself. That's one of the benefits of not having to buy a quad at a time and is basically the only reason I use a 50 watter. Tube maintenance/rolling is cheaper hehe.
Thank you. I see that you are over at the preamp thread a lot. I'm sure I'll catch you over there. I think I'm willing to try some new tubes in my DSL.
I put Tung-Sols in mine yesterday and so far I love them. The EL 34B makes for amazing sounding power chords!
removed E34L and put in my new quad EL34BHT Ruby in my JCM 800 2210 and rebias... ouf no contest... great improvement compare to JJ... i am buying some for my DSL 100 tommorow...
not much improvement in DSL100... i had svetlana...
I just tried the Rubys. I had a set of Wing C's on hand and the amp had Sovetecs in it when i bought it. The Ruby BHT's really woke this amp up.
She was likely set up for 6L6's as I couldn't get the bias up over 25 MA but these Rubys sounded great biased cold like that all the way up.Thick smooth and tight all the way up to max output. The Wing C's got farty as you turned up the volume and were thinner overall. However it may be due to the under bias. I will leave this one as it is wh the Rubys ( (she is a 2501 combo) biased this cold this set should last a LONG time
happy you tried them out... i run all ruby now on all my amps and the only one that had no change is the DSL 100... i tried another set of Ruby and same result... presently running in 2210... 4102... DSL 100... 4100... 4104...
Actually had originally ordered a pair of JJ EL34L's and the order got screwed up and they sent the Rubys by mistake. Glad they did as I really like the tone with the Rubys in this amp!
And the rest of the "family"
Tell me more about these BHT's. Are they the same physical size as the BSTR's? Are they a big bottle, bigger than the JJ E34L's?
And I am figuring these new EL34BHT's are Chinese made?
We have had a great response to our new RUBY EL34BHT tube. Many engineers have asked about what kind of power can be expected from the EL34BHT. In our tests, we used 600 V on the plates, 540 V on G2 and a bias setting of –54V. The tubes idled at 25ma each. The power output from a pair of EL34BHT tubes using these voltages was 70 watts at clipping.
The bottles are similar Ricky. Both Chinese made.
Bottles are close to the size of 6L6's and the tone is about smack in the middle between a 6L6 and a EL34.
Thicker than a conventional EL34 and about the same in length.
Re: JJ E34L vs Ruby EL-34BSTR
Ruby EL-34BSTR's are a special tube request, relabled power tubes made by Shuguang in China. Ruby EL-34BSTR's when you turn the volume up are going to break up much sooner than JJ E34L power tubes, and will sound warmer. Also they have a brighter top-end with more bite.
JJ E34L power tubes have the tightest bottom end of all EL-34's and have a much smoother top end, and slightly scooped mids, in other words not as bright as Ruby EL-34BSTR's or the SED Winged =C= EL-34's. It depends on what you are looking for. JJ E34L's are great for chugs and AC/DC power chord riffs if you are a Rhythm Guitar player. For a Lead Player I would go with Ruby or SED Winged =C= EL-34's because they both have more top-end bite to cut through.
I have JJ E34L's in my 1990 Marshall JCM900 MkIII 2500 and they sound great with it. But in my 1978 Marshall JMP 2204 I use Winged =C= 6550 power tubes.
