PV10AL cutting out
Posted: Sat Jun 17, 2017 5:13 pm
Hi all
I wonder if anyone can help. I have 20-year-old PV10AL preamp which has started cutting out on me - both channels go, and for about 3 seconds before coming back again as normal. This happens about once every 15 minutes of use, and usually during loud pieces of music. Incidentally when it cuts out you can still hear the music very faintly in the background.
Before I start probing around with a scope and meter, can anyone point me in the right direction? I'm assuming it is an HT power supply issue (because it affects both channels). But the fact that it is intermittent is perplexing - if it failed completely it would be a much easier problem to fix!
Many thanks
Mike
