My right channel has been giving me trouble for a while. I ended up replacing the RCA jacks for inputs and outputs. Now I'm noticing a significantly lower volume in the right channel, which I measured using a test LP to be about 3db lower than the left.
I think when I push down on the input it improves. I've tried tightening the RCA jacks but am afraid of stripping and ruining them, which I've done to several. Anyway, is there something I can do to get that extra volume?

You are posting in the Quickie forum, but the difference could as easily be in the phono cartridge or the phono preamp. Left-right swapping of cables and tubes will help sort that out.

Right, sorry. I've ruled out the phono pre or main amp. Different sources display the same problem, though I was only able to measure using the test LP.
Sound is centered slightly left of the middle point between the speakers.
I've stopped tubes and cables, too.

OK, so it's in the Quickie and it's not the tubes. It could be in the volume control - have you tested at maximum gain? It could be a failure of one of the cathode bypass caps, likely either a bad solder joint or reversed polarity. It could (of course!) be a bad solder joint somewhere, perhaps in the signal path but could be elsewhere - it's always easy to re-flow all the solder joints.

OK, will do. I had trouble with one of the inputs some time back. It wasn't tightly enough. I meant, it was tight, and wasn't wiggly. But it needed to be tighter. This solved some of the scratchiness I was getting. I'm thinking something similar may be going on...
I aim to upgrade from my Quickie/SEX combo to the Steremour II this summer, using the SEX as a headphone amp, and retiring the Quickie, so maybe I shouldn't waste too much time on this, especially since it sounds fine, even if slightly off center.
