First tests with my build of an "hybrid feedback" regenerative receiver

First tests with my last build of a tube regenerative receiver. The original design is by Vladimir Novichkov (please look for thread "6AS6 regen, mk2" on http://theradioboard.com for a detailed description). I opted for a simplified build (no varactor-based fine tuning, no tube-based AF amp, no AGC). Still, probably one of the ugliest buids ever seen :) Anyway, after some tweaking it's starting to work. The global tuning range is about 3600 kHz to 10700 kHz. Yes, I need a reduction drive for the "band spread" capacitor, otherwise it will drive me crazy very soon :) The small card at the centre of my kitchen table is a small JFET-based audio preamplifier. The hairy hand appering in the video is not King Kong's, it's mine 😁 Please have a visit to my blog at: http://radio-quaderno.blogspot.com/se...
