Heathkit HW-32A, Post Restoration

 These are such cool little monoband radios! I've had all of them...the -12 on 75m, the -22 on 40m, and the -32 on 20m. They'll do around 100w output, are fairly compact, and have a great receiver. They are phone only, but with selectable sideband, I'm sure a little work could easily drop these in the digital segment of the band for those modes. This unit was pretty clean, but I washed the PCB and cleaned it up, anyway. The tube sockets and tube pins got cleaned, a shorted tube was replaced, caps replaced, some resistors were replaced, an assembly issue with the rear power connector was corrected, and the receiver was DEAD. I found a damaged I.F. transformer, repaired a burned winding, and it came alive. An alignment was performed to get her at peak performance. Wow, amazing performance from a 60 year old radio. Here's a video and a few pics...
