SOLD

I am not going to be able to finish my 813/813 transmitter project.  This modulator deck is mostly finished.  I planned on using a Heising Reactor and a BC-610 mod transformer.

The variac is for adjusting the screen voltage, I think the torroidial transformer was 400V.  The Little PCB sequences the key up and key down.  The separate box contains the MOSFET audio driver by Francis Carcia WA1GFZ.

The chassis I made myself.  Fits in standard rack.

Make me an offer.  I would guess shipping would be about $50, you pay actual.
