Hi,
I finished putting my kit together and wired everything up with a slow blow 1A fuse. When powering on there is no hum from the transformer and the led on the board (led1) lights up and stays on.
However, I get 135mV (0.135V) across R19.
The potentiometer is fully counter-clockwise (anti-clockwise).
All traces read clean from component to component on the board.
Nothing has blown/burnt/gotten hot.
However the output to a 6 Ohm speaker makes an awful squealing noise.
The power transformer gives out 33.16 VAC to the board.
Any ideas?
Thanks in advance!
Mike
