latest known good schemo/layout/parts?

Post by krash »

OK all--

I have a Peavey Classic 30 that I want to convert to a 36W TMB and perhaps reuse the iron. This will be SS rectifier but other than that, basically I'm looking for the latest known "good" 36W TMB as a starting point. I ordered the "Richie" 36W TMB turret board from turretboards.com, tube sockets are on the way, and I will be placing a parts order with Mouser today.

So ...

is this the latest-and-greatest:

?

Or does this schematic contain the right component values (particularly the ones in blue):

?

...knowing that I'll have to tweak the ps using existing iron and SS rectifiers ... and I'll probably end up tweaking a lot about the circuit but I want to start with something that'll work right out of the gate and give me a baseline from which to tweak.

Currently I have a BOM together that I created from the layout drawing above, and then added the component variations in the schematic. If that'll cover my bases then I'll hit "submit order" right away :)

The layout is the current working version. You can substitute Richie's "values in blue" from Mark's schematic if you want...they're just tweaks.

Krash, I think I would sell the peavey...They get outrageous money for them. They are $500 new! you could ebay it for at least $300 if it is in good shape. That will buy you trannys, a chassis, faceplates and a turretboard. The rest of the parts can be picked up very cheaply at Mouser. Just my .02 :D

i don't think so. i could get maybe $300-325 for it ... which is not enough to cover just a cabinet and speaker for an 18W.

I like the format of this amp and will be putting channel switching and effects loop and all kinds of stuff in it. i think i'll stick with the peavey. i'll keep the original circuitboards intact so i can return it to stock easily and sell it if i want to move my "creation" to a new form factor.
