Default SVS sub Indigo board repair

I have an SVS sub model 20-39PC-Plus which has failed. It powers up but no output. I'm looking for schematics and any relevant info on the Indigo boards in it, namely:
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.

I was able to follow a bit of the layout by comparing to the Klipsch Promedia information compiled by Dale Thomson in Klipsch Promedia V.2-400, V4.1, V2.1, And V5.1 Amplifier Repair

Power supply voltages look good but the signal is lost somewhere. Without reverse engineering the whole unit...

Any help appreciated.

Thanks, Don Whyte

Hi Don, any luck? I have an SVS- 20-39PCi that has been hit by lightning. Found what I think is a bad cap. Indigo Board is 600109 Rev 6... No luck either. Do you know if the boards are similiar. I see a blown part on it that is what I think to be a high voltage cap (C417). I am looking for someone who has a picture of the cap that maybe I can get the value for it? Any chance these boards are similiar?

The board you have is not similar to any in my unit. I would think that if hit by lightning many other components would be ruined also.

Hi, I'm having a similar problem with a Indigo Bash 300W sub amplifier from a Tannoy TS10. It has the following boards;

600109
650038
630139
630137
660037

If anyone has schematics for these boards please let me know.

Do you mind sending me a copy? My TS10 just quit working and I tried to get schematics without success.

Thanks a bunch!!!
