In Reply to: My PQ kit 1 is done... posted by Vincin on March 6, 2006 at 07:03:28:
You've got DC on the filaments so there shouldn't be any hum at all. And caps and resistors don't just blow-up.
The Celius should be an easy, if not quite efficient load for the Kit. The Onkyo's didn't have enough efficiency or resolution to show the problems.
Break-in and power conditioning won't fix wiring/soldering problems but making it work is half the fun!
There's a cold solder-joint or two somewhere, probably in the grounding. Does the hum go up with volume? It's the signal hook-up.
Switch tubes. Does the hum follow the tube from one channel to the other? It's the tube.
Does the hum move to the other channel when you switch speaker leads? It's that channel.
Is the hum in both channels and not volume dependent? Prolly the power supply.
Trouble-shooting is all about isolating the problem to a particular sub component. Do that, then go back over each assembly step, re-heating each connection as you go. Make sure you can see the shape of the wire in the solder. Cold solder joints love to lurk in great big solder globs. It may mean disconnecting and removing a board but has to be done.
One WAG: the ground at the speaker posts is always a likely suspect.
