I'm really curious to know, how does your homebrew power supply tackle the 800Hz frequency requirement of the TBW? Do you have a schematic, or construction details? I'm considering one of these, but really don't want to have a huge motor-generator set. Thanks!

I'm a lover of all things electrical, mechanical, and old. I'm into preservation and restoration. I derive tremendous satisfaction from making old, ugly, unwanted broken things look and work like new again. I gravitate towards "boatanchor" radios, and have a fondness for the ruggedness and robustness of military radios. I also have a weak spot for anything wearing a black-wrinkle finish.I spent five years in the US Navy as a radioman in the submarine service. I was a SATCOM technician, and worked on the AN-WSC-3 VHF/UHF transceiver and its associated encryption gear, patch panels, etc. Left the canoe club in '96 after a car accident and subsequent spinal surgery disqualified me from further sub duty. For the last 14 years, I've worked professionally as a Macintosh Computer Technician, and for the last 5 years, I've been the service manager for an independent service provider here in Sacramento.
I love classic Mopars, and own a '69 Dodge Charger and a '72 W200 PowerWagon that I'm constantly wrenching on. I love old ships, and used to work as a volunteer aboard the WWII "Victory Ship", S.S. Red Oak Victory. I collect anything related to WWII Victory Ships.
You could also use two back-to-back zener diodes in the primary circuit of the power transformer to drop the necessary voltage. As with any method, the 'droppped' power is going to have to be dissipated as heat, so you'd have to do some calculations to figure out how much power each diode would n...
