An easier route might be one of the laboratory inverters - like this one I restored from a $100 ebay parts unit a couple of years ago.  The only noise is from a pair of muffin fans on the rear.

To the TBW4 crowd 

    Any thoughts about using an 800 Hz inverter to power the TBW unit(s) ah natural?  Using cheap power fets and a surplus big core toroid as the basis.  Standard iron E core units would probably be a stretch at 800 Hz and not sure how the calculations for those would go.  In any case as an hoarder of the TBW units and an original Power supply it's just a thought.  I have a good source of huge 12 or 24vdc units to power such an inverter.  Efficiency is not a criteria in the design as let's face it, the TBW4 is hardly the epitome of efficiency in the first place.

thank you e s 73

I am VERY excited to finally acquire one of these to go with my Rectifier Modulator Unit and HF transmitter.

Some detailed pix here (toward the bottom of the web page):


I have a pair of RBM receivers to go with these units.  Hopefully 2023 will be a VERY interesting restoration year for me!!!
