Hi
I'm having a problem with my Audio Innovations 800 Anniversary power amp, fitted with the Border Patrol MB power supply. One channel has just died. I've changed all the tubes but makes no difference. All the tubes (both sets) appear to light up and work ok.
Border Patrol have fixed it before - (almost caught fire- cathode resistors I was told) - but it's a real pain to send it off to them. Any quick fixes you can suggest? I'm OK with a soldering iron and can change caps etc but I'm not up to messing with the power supply.
I've looked a the schematic for the AI 800 series III on drtubes web page - is the Anniversary similar to this?
Whilst I'm at it, any mods you can suggest? Border Patrol on their web page do an upgrade for GBP 350, changing some caps to Black Gates and Hovlands. Any ideas?
Thanks for any help you can give.
John
