I have made PCB from schematic.
Both Power Supply and Amp Boards are ready.

There is difference in size & components size (resistors / Pot )

e-mail me, for further details, I will mail you pdf or PS Board and AMP board.

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.

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!.

Hi Hife,

If not too late I'm interested in 2 x amp and 1 x psu boards.
