hi all.
I've been housing as pre amp a project phono box rs for about 1 year now and I was very very happy with it. Now it's 1 month that I noticed that 1 channel (left one) sometime is much more quiet than the other.
What I already did:
Replaced all rca cables: Didn't solve the problem
Switched the cables left right between pre amp and amp: the low volume follow the low left channel of the pre amp.
Changed interconnections cart-tonearm: nothing changed
Then today I was playing music and as a while now the left channel was quite. I took in my hand the pre amp and magically both channels equalized. That lasted for a 30 min and then back to the same. I moved the pre amp again and that solved the problem again.
I suppose it's a connection problem inside the pre amp concerning the INPUT left channel rca cable.
Any suggestion-experience-advice on what to do?
Thanks a lot all in advance.
