 I've got a dead SVS 20-39PC-Plus subwoofer that powers up but won't give any output. The Indigo BASH amp boards appear to have rail voltages working but the audio signal is lost somewhere.
Does anyone have schematics, etc for the Indigo boards inside:
630096 Rev 0
630126 Rev 0
630127 Rev 0
640022 Rev 1
650027 Rev 2

SVS have been no help, and Indigo itself appears to have been sold to the Chinese company Sonovox and proprietary rights to the designs get in the way.

Thanks for any help.
Don

 I'm of no help, but being an owner of two PC-2039+, I'd would like to know what happened when you contacted SVS? Did they blow you off or not offer to fix it if shipped back to them?

See ya. Dave

 Welcome! Don.

over the years, I have seen subwoofer(s) come and go. You would be hard-pressed to find a more superb sub than REL.

 SVS did offer to replace the amp, at my expense. It's not on warranty. Prefer to fix it if I can.

 I Googled Indigo BASH amplifier schematic and up popped a few diagrams which might be helpful in guiding you. Sorry that's the best I can do for you.

Give it a whirl.

 Many thanks for that, I looked extensively through the link and could find no schematics about the SVS Indigo boards used in the 20-39PC sub. I figure the only way to get the schematics is to reverse engineer the whole unit.
