My GS35B Homebrew HF Amp
With 100 watts drive I see 1400 on 80 meters and about 900 on 10 meters.
I no longer have to try more than 2-3 times to break a pileup to work a DX station :)
Power supply is 3600VDC 500MA
This was my first amp project and it took me 9
months to finish. Mostly because I was terrified of the high voltage.
I purchased a variac and a VOM that could read up to 6000 Volts and that helped me get this thing done.
This is the W6PO design bias board using a 35v zener.
I built my own tube socket.
I'll make you one for $35 shipped!
This is an 1800RPM 135CFPM Dayton blower. It's very quiet as far as blowers go.
I cut a 3 inch square hole in the bottom to allow air flow from the blower.
I get a roller inductor/turn counter set from W4IMD.
The turn counter is VERY nice.
I used a modified version of this schematic.
1) I used a roller inductor/turn counter
2) No tuned input
3)The grid meter was replaced with a RF Output meter.
