Hi!
Just a short update here. I finally discovered the real problem. And it is quite embarrassing.... As I'm using a manual band switch I should have removed U1 from the filter board. I didn't. After removing U1 the amp works as intended. Full power on all bands.
@jim: do you have any arduino control boards left?. I think I have graduated on the amp part and I'm ready for next step..

Hi Ulf,

I'm glad to hear that you found the trouble. The controller boards are gone but I am working on a small board that back-packs onto a 4.3" to 7" 800X480 color LCD with capacitive touch screen. It also has a Teensy 4.0 and will have provisions to connect to the amp, LPF and T/R boards. IT has analog inputs for F/R power, temperature and an IDD sensor.

Once I get a prototype running I'll post something about it.
