HEATHKIT SUPER C-3 modifications
« on: January 25, 2016, 05:04:40 PM »
I sold dozens of C-3 rebuild kits on ebay that added a gain of three amplification for better sensitivity and regulated the supply with zeners that also corrected the leakage test voltage at the low settings.  This used the existing triode that was used as a rectifier.  I ran out of parts a year ago and packaging the kits was a pain.  So this will be the repository of the info.  I'll post more later.
