I would say not...
Even the voltage regulator transistor Q1 doesn't have a heat sink on it, and it looks like its collector is tied directly to the NEG rail on the DC jack..
5V on pin 6 is excellent! I cannot get my poly 800 to supply this without using the batteries...
But I would say that Q18 should NOT hot....
Its collector looks to be hooked up to some sort of transformer?
Maybe test the voltage on that?
Cheers,
Nate
