Thanks everybody.

Here's finalized F5 board (didn't check for errors yet). The size is 2.4 x 1.7

 

[Peter Daniel]

And that's how it compares to F4:

 

[luvdunhill]

I was playing with the idea of F5 as well, after all it would be nice continuation of the whole series of those mini amp boards.

Peter, could you accomodate the assymetrical mounting pattern (i.e. for the stand offs) that the F4 board uses as well?

oops, just saw your post... yeah, that won't work...

edit: what about accommodating the Caddock power resistors?

Thanks a bunch!

Peter, how much is the F5 board cost?

 

[Peter Daniel]

I will try to modify it for Caddocks power resistors.

Two channel F5 amp board would cost half the price of F4 board.

 

[Peter Daniel]

And now ready for Caddock power resistors.

 

[luvdunhill]

could you not more R1 and R2 to the left then rotate Q1 and Q2 so their faces can be coupled together? you have to move the ground, but looks feasible.

 

[zristic]

Payment sent for one F3. Thanks.

 

[rhing]

Payment sent for one F3 amplifier PCB and one F3 power supply PCB. I will hold off on the F4 boards in favor of the F5 boards that Peter is proposing.

Peter, thank you very much for your service provided.

Mithomas, thank you very much for organizing the Group Buy.

Mr. Pass, thank you very much for sharing your IP.

F5 board grounds

Hi Peter


For the F5 board, could not find out grnd, or PS V+ or V- grounds. Are you planning on using a chassis star gnd?

JimS

Does this help?

Input - green is after diode DC 0v, yellow is 18v.

DC input after diodes

white is v+, wire two hear for a channel each. the bare wire is the star ground point, yellow is v-.

V+ V- and ground as bus wire
