Re: Looking for help please with 1964 Trio W-41 stereo valve amp
Hi Lawrence,
Signal is getting through the phono stage to the speakers but no amplification is happening. It's very very quiet and thin, like putting an MM cart into a regular line level input. RIAA and preampfification does not seem to be occurring.
The cause of the problem is still under scrutiny.
Despite establishing voltage readings suggesting both 12AX7s are functioning ok, we have found both 270k resistors have failed, R3 and R103 and I'm awaiting components... I think we're in a 'watch this space' situation now although great advice is coming thick and fast.
I'm sure there are 1 or 2 who've looked at my pictures and thought... "I'd gut it and start again", and they may be right, but I'm keen to do what I can with my limited skills and equipment to try my best with the help of this forum - for now.
