Hi Peter:
I am interested in getting some F5 and PS boards. I have sent inquiry at your website but have not heard anything back yet. Just wonder what is the best way to reach you.
Thanks!
If yes, then any expected datesDo you plan to design PCB's for F5 Turbo?
sorry andrew, newbie mistake, I had the lightbulb draining the Voltage.
removed lightbulb and all good now. biased to .614 and .600 with 0 offset
though seems to lack some gain on 89db speakers.
Hi,
You can increase the gain by reducing the neg feedback (by increasing R5/R7 & R6/R8 from 2x100ohm to 2x200ohm and R1 & R2 from 10 ohm to 20 ohm)

Peter I am in for pcb 2 channels and psu
Peter I am still interested in psu pcb.

Both F5 and PS boards are available.

the gain is set by the ratio of those resistors.
Changing both, as you have shown, leaves the ratio exactly the same, i.e. the gain is the same.
