I built the Elekit TU-8500 a week ago. Everything works with the exception of the right phono input. Very low volume. Need to unplug the left channel to hear right channel with volume up at 1/2. I swapped the op-amps with no change. Any suggestions? 1st post to this site.
Victor, please advise if you can help.

Thank you for your quick reply.
Before contacting you I verified the placement of all parts, reflowed all solder joints on the right side phono components, verified continuity between the 8 contacts inside the sockets for the op-amps and solder connection to PCB, and reflowed Jack 1.
All voltages on the test points are good. VEE is - 11.91, VCC is +12.1, 140 v point is 145 volts. H+ & H- are also good. 12 volts.
Are there any other voltages I can check?
