Jun 30, 2006 · There are 3 issues... Plate current, filament current and output impedence. A 6V6 in a 6L6 circuit will typically run very low plate current, thus a smaller value cathode resistor would be preferred for 6V6s. 6L6s require about twice the filament current of 6V6s...so 6V6s are fine in a 6L6 circuit, the opposite may not be true.

Jul 13, 2020 · Hello All I would benefit from some opinions/advice on selection of an OT for another amp I will eventually build with a pretty straight forward 6V6 push-pull power section. I want to purchase the transformers now because I want to get a choke to play with a modification that I am doing with...

Mar 10, 2009 · I really wish I had a metal 6V6 here to measure, so we could find out conclusively whether the shell is "hot" (my suspicion is that it is.) I went around and tested the metal 6L6 and 6F6 tubes that I have. Curiously, a couple of my Sears Silvertone 6F6's did not have continuity between the shell and pin #1.

Oct 17, 2007 · Funny .. I'm running a 6K6 in my 5E1 tweed champ amp I built from scratch (using the standard Fender schematic - but with a tone control added) ... with no problems, and never blown a tube.

Apr 4, 2022 · Because 6V6 amps run their power tubes close to max output, the breakup point is usually lower on the volume dial, and, to my ears, 6L6 power tubes seem to give me more clean headroom, with a tighter, more focused bottom end.

Dec 14, 2014 · I don't know about "old" sound. I mean, if you want that, shop NOS. For new production, Tung-Sol and TAD are excellent choices, in my opinion.

Mar 14, 2022 · Champ-esque, yes. No reason you can't use it for push-pull, it just isn't on the datasheet that way. See also 6K6 (true pentode) and 6Y6.

Feb 18, 2010 · Very little shift in tone but you lose a couple watts. They're both beam power tubes. No one makes a new 6W6, no big deal. They sell for around $5.00 each NOS. Next, you can change to a 6K6 or a 6F6. They're both pentodes. There will be a tone shift. I like the 6F6 in small amps, it gives me a more agressive tone.

Nov 17, 2012 · Hi folks, I finished up a 6g2 recently, it has been fantastic and I've been having a blast auditioning tubes from my meager stash. However, I have run into trouble with a few sets of old 6v6's in this amp immediately drawing a ton of current and starting to cook. It …
