I am in need of a quad of 6L6GC's for a Tusc DF-100. It's a Blackfaceish, all tube amp from the early 80's. Which new production 6L6GC tubes are you guys using? Which NOS 6L6GC tubes are you using?
Thanks for the help.

What is Doc running in his 6L6 amps?

JJ 6L6GC's came stock in my Therapy from the Doc.
Aside from those, the Tung-Sol 6L6GC STR and TAD 6L6WGC-STR (the short-bottle ones) are probably the best new-production ones out there.

I am using JJ's for repair work. I don't use anything Russian. I wouldn't spend the money for NOS tubes to use in that amp. You could easily spend more than the amp is worth in total IMO. Those were hybrid amps, weren't they?

I contacted Jeff Bober to see if he could give me some info on it. He might feature it in his monthly Ask Amp Man article in Premier Guitar Mag., if he can find more info about the amp than I was able to find. Bluzman had given me a bit of info on the amp awhile back, but that info is no longer available to me. Thanks for the tube info guys. If Doc is using the JJ's they will probably do just fine for me.

My guess is that those 12AT7's are being used as a reverb tank driver and phase inverter/output tube driver. That type of tube doesn't usually work well in the first and second gain stages.

I was thinking one of those preamp tubes was for a phase inverter. However reverb send and recovery makes much more sense.

Hi, I'd throw in an option that I've found is very nice if you would like a 6L6 tone that is a bit warmer in the mids and rounder in the highs. TAD 6L6WGC-STR is a very nice tube. Carr Amps is putting them in their new 6L6 amps these days, now that the Winged C brand is defunct. They sound great in my Ramber.

Thank you Rick. Winged C's definitely came to mind as have RCA's. $ is a consideration for what I will get. I have been considering the Ruby 6L6GCMSTR, but mostly based on reviews for their EL34BSTR.
I like the recommendations I'm getting here. You guys are much help.

Those tubes are the heart of the amp imo. I would get NOS you would be shocked how little you will spend with such great results tone wise. I realize you need a quad. Check with the tube depot they always have something affordable

Jamie, I prefer to go NOS. We'll see what happens. NOS are like gold these days...$$$.

I still haven't decided on the tubes to use in my Tusc. I'll start out with a cheap set. The amp is probably 30 to 35 years old. And the original tubes presently in it are Russian made 6L6GCs. I don't know what will happen when I get her going. Jeff Bober recently did a piece on my amp in the March issue of Premier Guitar. He gave me some troubleshooting suggestions to get me started.
The Tusc has sat for many years with no usage. Should I replace the electrolytic caps in it? Wouldn't want to loose a tranny to a fried cap.
Oddly enough the power tranny has much more mass than the output transformer.

If the amp has not been used for a long time it should be powered up in steps using a variac and monitoring the current draw. Similar to how you would form new filter caps. That will give you the best chance of not having to re-cap it.
It's not at all unusual for the output x-former to be smaller than the power x-former. Several BF/SF Fenders are that way. You may just be used to seeing the beefy iron in "Z" amps.

For my money, I'd go with NOS JAN Phillips 6L6wgb. They will last way longer than new production. But if I were buying new, it would be the TAD's.

It turns out the reverb send and return is op amp.

These would be nice tubes to try. I bet they sound real good in that Z!

Yeah, Doug. Dr Z has tweaked all his amps to wring as much outta current production tubes as possible. When you add some old gold like these, his amps really sing....

Lee is good you didn't need a quad. That would run about $700 wouldn't it? I found 2 pair and thought I was in heaven. I ended up having to sell with my amps in 2009. I bet those babies are still going strong.

I bet those babies are still going strong. I don't want to put RCAs in my amp until I get it up and running correctly. That would be a quick way to flush $700.

I wish I could get me some nice RCA blackplates. Brent Jesse has some anos for 179 and he always been real good in backing his tubes with me. He has a couple of pairs I think and I'm running an amp I have with KT-88's and I think that a pair of RCA's are fixing to be put in there. The TAD 6l6's sound great but I know the old stop signs would kick a little butt. Lee you don't feel like being in the giving mood buddy. LOL Those boys look nice.

For new production 6L6 I really really like the Groove tubes GE 6L6. They're not being produced any more to my knowledge but there seems to be some still available. NOS GE are some of my favorite 6l6 ever even including RCA, and these groove tube GE's were made on some of the same tooling and materials were available. They sound excellent! I think a great alternative to nos set.
