Default Re: Wartime civilian receiver what to replace Westector with ??

Back to the OP request, a few silicon diodes in series, 4V would be 4/0.7 = 5.7. As diodes only come in integers tweak the number for best performance. I had one of these sets nearly 40 years ago, I replaced the Westector with a power diode, that was all I could find at the time, it worked!
