thanks for the info!
i know there are multiple capacitors, which is why i gave the info regarding it's relation to the 'on/off' switch. doesn't matter, as it is the least of my worries since i can remove it and go ask someone in person for that info.
as for the speakers, both are wired to the same TRS, and i have no 'aux' input for them....or near where i'd plug that in. my options on the back side are '1' and '2'.
the fuse is a given...i'm capable of reading which parts it might need when the info is readable on the amp (even if i can't describe which capacitor i speak of) new to tubes and this particular board; not electricity.
could it be that Peavey once sold the regular 'Classic' as one of several models (or even just a few) as a subcategory '100 Series' aside from it's 'B Series' label? after reading Enzo's response, i checked the back to see if i could make further sense of numbers on either side of the switch. since now the '200' is clear to me and logical in and of itself, the '100' on the other side only makes sense when combined with the 'Peavey' label in the middle, position a few mm higher than the '100' at the bottom left and 'series' at the bottom right. just a thought, as otherwise i'm out of explanations for the '100' written on the right side of the power switch.
also, did the foot switch for these models have a standard 1/4" or something else (mine almost looks more like a midi input - but not). the reason i ask is that the foot switch that came with it had a 1/4" input that doesn't match the amp - so i'm asking if either it sounds more like a customization or that someone had put the wrong foot switch in with the amp (that kind of stuff my dad has no clue about).
thanks again for the help and it looks like there are still a couple mysteries to be solved. i'll begin looking for the schematics for this model and go from there. thanks!
