Anymore ideas on the low power problem?


Only getting milli-watts. Adjustment of the bias pot seems to have no effect on the supply current.


A loud HALLO only gets a small flicker on the power meter.


I've looked at the driver transfomers. I can't see any shorted leads

Any chance of a stage by stage diagnostic aid please?

I don't have ready access to a scope so DC measurements only preferred or a ?pointer towards a simple RF probe I can build.


DDS VFO ready to go.
