Hi
I had the same problem and it was the hot and I didn't use original part and
there is difference on readings between collector and base. So if you are
using generic part I think that is the problem. as soon as you replace the
hot that should solve the heat problem.
good luck

Had a shorted HOT 2SC4927 and the SMPS transistors
Q601,602,resistors,etc.
Installed an SMPS kit (OEM-Q601,602, 3 VDRs, 2 resistors). and an OEM
2SC4927 HOT. Powers up,plays good, but I think the new HOT runs hot.
What other parts are usually responsible for this?
