Well after discussing grid leak and power detectors on my Majestic 50 thread and experimenting with changing to a diode detector, I’ve decided to dig out my only other radio I have to be a candidate. It’s a TRF set with a grid leak detector. The purpose being to see if the inherent problem of distortion from a grid leak detector can be improved upon. It should have easy access to the circuitry that I need to work on. First I need to restore/repair the set to working condition. Right out of the gate, one big problem is the three tuning caps have what appears to be pot metal pulleys that are totally crumbling away and metal bands that run between them that are broken. So the research begins!
