I’m sorry, this is well out of my wheelhouse. Have you tried contacting SVS? Their customer service is top notch. They have Sunday hours as well (12-4 pm ET).

I already did... they are not able to help. Hopeless customer support in understanding a basic query.

Ugh. Well that stinks. Hopefully someone in the forum is more knowledgeable than I am. Sorry!

May be hard to find. I have one, but it's broken. Actually, I think I finally trashed it after several years of storage.

Sorry, i cant help either, but i were in the same boat a few years back.
The amps are made by Indigo in Canada. When mine broke i tried to figure out what was wrong with it. Could net get my hands on a circuit diagram so it was all done by trial end error. An equal amount of both actually so it ended in an error.
I even bought several broken amps to try and figure them out (all had the same fault in the powersupply). I actually soldered and desoldered parts on them so many times that the circuit traces went fubar eventually and i no longer bothered with it. Im not a very good amp repair man though. I just dabble with stuff like that from time to time in my garage
Ended up buying used a 3kw PA rack amp for it and have used that setup ever sinse

All that said i think i read resently somewhere that the rail voltages are variable on theese

What @kickerz said – outboard amplifier. It shouldn’t be hard to convert the 20-39 to a passive sub, enabling you to use the amplifier of your choice. I’ve done it to two subs. It’ll be a piece of cake for someone like you who’s capable of doing board-level work.

Wayne
