With 13.0 volts at the input jack (from a bench supply), and 12.7 volts on
the circuit board's + bus, I am only reading 1.4 watts maximum power output
into a 50 ohm dummy load. I haven't found a problem using the
troubleshooting guide, voltages at Q1, Q4, Q5, and Q6 are where they are
supposed to be. T1 and L3 look OK to me - but if I'm a sub-par winder can
that lead to lower output?
I have the resistors for the higher power output mod, but I'm trying to rule
out build problems first.
Any additional ideas?
Thanks,
Chip
