As additional follow-up on my own post, I measured the Polysix again last night after additional playing. The metal bar on the power supply measured just over 145F (63C). That seems pretty hot to me.
Is anyone able to take any measurements of their power supply to see if this is normal?
(BTW, a meat thermometer or a candy thermometer would work fine for this measurement. An oral thermometer would probably work on the outside of the synth on the back panel)
Thanks so much!

After focusing on having fun playing the thing for the last month or two, I'm noticing that the Polysix seems to get quite hot on the back panel. Because I've added two new microcontrollers (plus associated components) and powering them all off the Polysix's built-in power supply I'm worried that maybe the extra heat is my fault.
