A agree just been really curious. I’m going to be doing a retube soon and will probably just stick with kt 77’s... now the question is JJ or gold lionsVentura":3mhhmlb0 said:Likely too hot and big a bottle. EL34 / KT77 etc.
I've got a D-Moll, I have to say, I do like it with the KT77s. I have used 6550s in some of my Diezels, I'd be up for trying my D-Moll out with some 6550s, but it just sounds damn good with KT77s as is.
There was a JJ/GoldLion shootout recently posted - unsure if it was under this subforum or the main RT thread. JJ had some advantages - go figure!! And I've been a diehard GoldLion fanboi since they'd come out. But something's definitely shifted in the JJ camp, they're putting out some really fine bottles at not so "boutique" pricing. Check the shootout - it was pretty cool to listen to. Neither one was better than the other - which unto itself is kinda surprising - and both had "artifacts" that separated them from one another that were either liked more or liked less. Honestly I was surprised.magh8":3ncy2szd said:A agree just been really curious.

have anybody checked bias on JJ after mouth or two of usage?
Friend of mine has JCM800 of old RFT EL34 for 15 years without any problem. 15 years Carl, I wish I could find 6 matched for reasonable money, but happy with Genalex KT77. way better than JJ

I bought a quad of JJ KT77 for my Diezel Einstein and after about a month one of them had failed. Got another matched quad promptly shipped to me from the vender free of charge. Biased them up and have been using the same set for about 9 months now. Checked the bias the other day and it's still spot on where I set it at 70mA. I don't know how long they'll last, but I've been happy with them overall.

Well, ask Reinhold, or Peter D., or Friedman, or whomever - they're NOT in control of manufacturing the powertubes. And since, honestly, the sky's the limit as to what price & quality the powertubes "could" be given any end-consumers choice(s), it's just not in the manufacturers' best interest (nor the end consumers') to tack on that extra cost to an already expensive piece of kit.belensky":25e3lsc4 said:Ventura":25e3lsc4 said:and have seen a number of higher-end/boutique amps come with JJ powertubes as stock.
Yeah recently got Bogner Ecstasy Anniversary and was a bit disappointed that they use a lot of JJ, tubes, I mean for that expensive amp I would expect something better.
