SWR amps anyone?

Availability.

I like the MJ15xxx series of transistors for commercial power amps - most of what I do is pro audio anyway. They are very popular and used in many places. They were originally Motorola, now ON Semi. Look it up at Allied and they should have a data sheet, if you can't find it at ON or elsewhere. The 15024 is a 16A 250V part. See the SOA chart for your application. QSC on their older amps went from 424s to the Moto types with few other changes.

Looking for schematics and / or repair manual for SWR Silverado Special ? Anyone ? Please ?

Did anyone end up getting a schematic of an sm-900 or similar?

This is the schematic for most models. At some point just before, or maybe after Fender bought them out. the SM-900's changed the PCB's from green to Blue and made a whole slew of nasty changes adding all kinds of saftey crap in there and really mucked them up.

This schematic covers the good green board amps.

swr 4004 350 swr2000 power amp module

I have a workingman's 4004 that was blown up and then hacked up by an evil tech.
I have the schematics but a PCB layout with part Ref.#s would be extremely helpful in resurrecting this amp.
I will pay if necessary for the correct PCB layout.
