I have an issue with a PA TT2400.
It gets burning hot right in the preamp stage area. When I got it, it had a shorted B631K transistor and 2 burnt output transistors (2SA1685). I replaced them both. Now it works but gets very hot. Burns your finger, but plays fine on my test bench. Has no fans built in. I haven't closed it up yet.
I posted a picture. Can any one give me suggestions.
The 4 Capacitors shown are 330uF@ 25V.
Any suggestions would be appreciated.

I'm not sure that I understand the question. The two large resistors are likely causing other components to get hot. It's normal for those resistors to operate at high temperatures.
