Peavey Classic 50/50

[cobhc]

Just got one of these beasts and im loving the sound coming out of it, but i got two questions for you amp buffs, is there a chance i could fry myself if i pulled 4 of the 8 tubes out to reduce it to half power, or should i let a tech do it. And secondly, what are the best tubes for this poweramp to get me some serious low end out of it, i like a real big lowend punch. Thanks in advance guys

Should be 6L6 tubes... I'd look to "SED Winged C" http://tubestore.com/6l6gc.html

Look around...

I'm not a fan of pulling tubes. I feel it doesn't agree with the transformers very well. Just my opinion.

Re: Peavey Classic 50/50

but theres no huge voltages going across em to fry me? lol just im trying to get the tubes going at lower volumes.

Re: Peavey Classic 50/50

There is only around 450-700 volts going through them, even AFTER the amp is off for quite a while. Just don't put your tongue on them I guess.

I know what you're trying to do. I just won't do it. Although the Peaveys transformers are hardy in those amps. It alters impedance, and is a little bit more involved in that area than most think.

my classic 50/50 was el84's and a couple of 12ax7's. open it up. it the tubes are big then it has 6L6's. if they are skinny then it's el84's. i know the classic 120 and 60/60 were 6L6.

Re: Peavey Classic 50/50

Re: Peavey Classic 50/50

yeh i'm sure i've heard everyone say the 50/50 was el84's

Re: Peavey Classic 50/50

That amp has el84's. Why remove 4 tubes when you can run on 1 channel @ 4 tubes = half power [img]/images/graemlins/scratchhead.gif[/img]

Re: Peavey Classic 50/50

Re: Peavey Classic 50/50

hmm, can't seem to get it to run in stereo with my 1936 cab, the manual only shows stereo application using two cabs, anyone got any ideas?

Re: Peavey Classic 50/50

Here's a diagram of how my rack was setup with the same amp. The OR setup is using a single 1960 stereo cab ONLY:

Re: Peavey Classic 50/50

Nice graphic there catzodellamarina. What did you do that with?

Just take pics from a website and impose them in an editing program?
