No power supply came with the radio. I have one ordered of owner claims all voltages are good. I had tube radios back last century and like a dummy got rid of most of my gear now I got the tube bug again. I will take time to check the resistances while waiting for the power supply.
I know I have more questions down the road. I have a ocfd now but would consider adding a dipole cut just for the 75meter band. Page 51 is a detail view of the front panel and an explanation of all the controls and how they should be used. Given that the rig works, this could not be any simpler.

The cathode and screen of tube V9 are connected directly to those of tube VZA. The meter, which is connected inthis circuit, indicates received signal strength in S units, as the AVG voltage changes the current in V9. The meter functions as an ALC indica- tor when transmitting, without any switching. The amplified signal from V9 is coupled through IF transformer T3 to the grid of product de-. Previous Next.

An accessory socket is wired into the circuit so the Heathldt plug-in Crystal Calibrator can be used with the Transceiver to provide accu- rate frequency checlcs at kHz intervals.
The terms are used as follows: Hz hertz : cps cycles per second. Refer to the "Kit Builders Guide" for complete hirer-martian on unpacking, parts identification, tools, wiring, soldering, and step-hy-step as- sembly procedures.
Install the tubes in their reapective sockets. Install the pilot lamps in their sockets. Be sure the one lamp does not touch the case of the meter. Loose crimped connections should be clean- ed and soldered. Place resistors in distributor system. Whine; varies with engine Speed.
