Quickie left channel cuts out when I install RCAs

[bare]

Status on Quickie 1.1 and non-working  PJCCS board...

I decided to pull the board, unable to get left channel to work, no voltage to left side.

Powered up Quickie, rechecked voltages (all in spec) this is what I found:

1. With RCAs installed on input #1, left and Right work great.
2. When I install second set of RCAs, on input #2...it cuts out the left channel.

Why is this? All voltages good/wiring/tubes/interconnect double checked.

Could explain why PJCCS left channel does not work? Any help with the experts out there?
-thanks

Is there a difference between the cables that you're using?  Is there a solder bridge across one of the input jacks?

Generally this will not have any impact on the functionality of the PJCCS.
