6M5 EL80 looks so much the power pentode in the ECL86 or the EL41 , not quite a EL84.

too late!
i stripped the chassis bare. started tinkering... ended up with... cathodyne/concertina phase inverter (1/2 a 12ax7), "james" style tone control, three 1/2s of 12ax7's for the preamp side of things, leaving me with one spare socket. which i utilized with another 12ax7, first half driving the (piezo) reverb with bootsrapping for the super high impedance, fed from the preamp. then the other half is recovery, blending into the phase inverter. cant really recall how i hooked it up but it works quite well, being able to mix wet and dry, and get reverberating distortion, not distorted reverberation... sounds ten times better than it did! especially the reverb... piezo reverbs cop some flak, but i dare say thats because theyre used like they were in the teisco...badly! all about impedance matching, really.
lost the tremolo... 🙁 oh well. you soon get bored with metronome like effects.
um...what else? oh, asked a friend to ask a friend if he had any el84's he wanted to sell... gave me a pair of (slightly used) mullards, and sold me a set of NOS AWV/radiotron's...
sounds awful (dead, quiet, and bassy) through an ebay cheaparsed quadbox, absolutely screams through an old peavey 12"... methinks i should mount the speaker in the quad box, only reason i use it is because it is the exact width as the amp, looks like it was meant for it.
that was another lesson...dont judge an amp too harshly until you have tried various speakers on it...
