Pictures 53 to 57 show the rig in more detail.
I have coils for 80 and 40 meters, the rig is silent,
no fans or variac hum, the power supply is selectable
on the front panel between 1200, 1300, or 1500 volts roughly.
The rig needs about 20 watts of RF drive, and about 15 watts
of audio drive (8 ohms), to give around 300 watts carrier out.
All the parts are at the kilowatt level, nothing gets
warm or will crap out even if you left it keyed up for a year.
Step start is built in, along with push to talk, and negative
Everything is metered and adjustable.
The mod transformer is an old RCA that seems to sound
VERY good, 10,400 ohms to 4350 ohms.
The power transformer matches the mod transformer, RCA...
The power supply diodes are 14kv at 1 amp each, and there are
4 of them in half wave center tapped setup.
Final tubes can be 811, 812, 572b.
