Joule Electra VAMP

[dfal]

I'm looking for a schematic for a Joule Electra VAMP integrated Amp. Mine has started to intermittently cut out on one channel. I've contacted Joule Electra, but I'm not sure if they will get me a schematic or even have one.

Any ideas for troubleshooting would be appreciated. I have isolated the issue to the right channel.

Best regards,
David
