N-channel layout question

[JBL]

In anthony N-channel amp does the phase splitter transitor(Q13) need to be mounted on the same heatsink as the output device?

The schematic can be found at:

and yes yuo do have to have it mounted to the heat sink. if you dont youll have a nice blown board like in the pic in the link above

Q13 on heatzink?

No, It would not need to be.
Actually it is best to use a separate cooler.
This transistor does not control the idle current.
That is up to what I can understand.

Maybe I am right after all.

hmm JasonL I think that you mix it with the thermal sensing transistor.

I'm talking about the phase splitter wich is nowhere talked about mounting it to the main heatsink(it is mounted on the main heatsink with the original pcb for anthony)

I just want to be sure.
