Heathkit HR-20, post restoration

 This is a Heathkit HR-20 receiver I restored. I didn't get any pics during the process. The finished unit is great, quite a nice little receiver! I found issues in the wiring of the band switch, but otherwise it was operational from the start. I did the typical stuff to it...recapped, changed a few resistors, cleaned the tube sockets and pins, and gave it a full alignment. One of the unique things about this receiver, is where someone built the entire receiver power supply under the chassis, and mounted the transformers on the back. Cool work! I was very impressed with the sensitivity and overall receiver performance. Here's a video and a few pics...
