Default F1 Board Prototype tested

hello all..

F1 Board prototype is ready, working fine .

Now that I have a working F1 Amplifier.... Observed the following...
(I did not put Heat sink.)

MOSFET becomes Very very Hot.. (Q3 and Q4 Smokes with out heat sink)
Thick Heat sink with silicon paste and insulation is required.

Quality of sound is very good.. !

Instead of ztx550, BC557 is used.

Default Are PCB Available ?


I don't see any further posts on PCB.

Are they available.. ?
I am making PCB for myself, I don't mind making few more. !!! But there is no match for Origal PCB's!.
