Audio issue a couple of weeks after Moreplay Upgrade [resolved]

Hello -
  I wanted to ask some advise as I find myself in a pickle. I built a Moreplay preamp a couple of years ago and it was a very successful build! Been sounding beautiful w/ my Dynaco ST-70. So as soon as I saw the upgrade kit, I jumped on it! I meticulously installed the upgrade over the course of a couple of nights, tested and when I put the Moreplay back in my system the improvement was SIGNIFICANT!!
NOW...here's the bummer part :(  - the other night I fired up the system and the audio was low and distorted in both channels and seemed to get worse if I tried to turn it up louder. I tried both outputs from the Moreplay with my ST-70 as well as my headphone amp with every source input and it seems to come down to the Moreplay. My problem is that I AM mechanical, have soldering skills and was meticulous and extremely careful with the build but I don't possess the electrical knowledge or have the experience to troubleshoot the issue. Can you help me with that? I'd be so depressed if I had to put my Moreplay on a shelf as decoration (gorgeous as it may be!!Lol)...pride of building aside, it sounds incredible and I hope I can find the problem and repair it without spending a ton to involve a technician - thank you all for any help you can offer!!

There are voltage checks in the manual on pages 25 and 28, I would start by double checking that those are all correct, and posting what you find there.

Will do tonight, thank you!

I’m having trouble with my Moreplay a couple of weeks after installing the upgrade - was working beautifully for two weeks and now low volume distorted audio through both channels. I’m doing the voltage checks to begin troubleshooting but wanted to ask where I should clip the negative lead for the high voltage check now that the volume pot has been upgraded to the board mounted type?

Paul Birkeland:
If it fits, you can clip it to either of the black wires where they connect to the input selector switch.
