I totally did not expect to see that this type of waveform was giving me this Ohh Sooo Sweet Sound!!!
There is probably loads of theory to discuss about that scope-traced waveform, but suffice to say that is the signature of a well done guitar preamp which pretty much nails that overdriven sound.

The Peavey classic 30 and classic 50 both use 4 EL84 outputs. You won't get the same exact tone or the same power supply sag compression, but you can install a half-power switch to disconnect two cathodes. A power soak resistor switch helps too. If you search there's also the Blue Guitar mods for the Classic 50.

wow, I thought the 30 was just 2 el84's, learn something every day.
I have a friend who will just pull 2 tubes out of his 50
I'm not that brave.

Wouldn't have thought so?, 2xEL84 gives about 12W, and 4 gives 24W or so. Bear in mind these are 'proper' RMS watts at reasonably low distortion figures, not guitar massively distorted ones.

Likewise EL34, 2 are 25W, 4 are 50W.

If I remember correctly the original Classic had four 6L6's in it.
Maybe it was modded for them I don't remember as it was 32 years ago.

I know this because it was a friends amp and one of the tubes exploded and took out the power fuse.
I just happened to have a few of them and 20amp ceramic fuse with me at the time and got him back running again instantly.

We rocked it for the rest of the night with no other issues.
Ever since that night I have always wanted to get one but they had quit making them!!

The next time they reissued the classic it had a solid state preamp so I didn't get one of those and I ended up with the Peavey Renown 400.
The original classic was all tube.

I'm talking about the newer Classics mine is a classic 50 with 4 el84's which I always thought was typical peavey BS because they over rate all of their amps even their solid state amps.

The "tweed" classic 50 really puts out 50 with the same output tubes as the "tweed" 30. The "tweed" classic 100 is the same as the 50 but has two of the output board and cage stacked and bigger transformers. The EL84's just do sound different than just about anything else IMHO, chimey clean like a small VOX and break up early. But a VOX 50 went to El34s; I don't know of anything else but the Peavey that used those crummy little EL84 table-radio tubes to such extremes.
