Has anyone ever seen or maybe even built one of these (or a similar product ?).
Interested in it because I would like to EXACTLY know what voltage the heater gets from the replacement Amplifone HVTs. After all, the 25” med-res tube I’ve got in my SW cockpit is the only thing I probably will ever have around here….
Schematic looks simple enough…..finding time to build it is something else and regretfully no PCB lay-out with the article…
Cheers, André
