1972 Road Runner Windshield Wiper Motor

 This isn't radio, but it's a kinda cool piece of electromechanical tech from a 1972 RoadRunner. A friend brought this over and needed help with it for a '72 Road Runner he's restoring. 

It's a windshield wiper motor/gearbox. There are kinda hard to find, and even then, you're getting 50+ year old pig-in-a-sack. I started digging in and found some wiring issues in the motor where the field and shunt wires were grounding to the housing, the brushes were totally wonky, the park switch was bent around backwards, the gearbox was seized with solidified grease, and the home switch actuator had tried to force itself past the internal stops. Here's a few vids and pics. I'll comment on the pics to better explain them. 

It's all running smoothly, cleaned up, and ready for a shot of paint!

Here's a couple of docs that helped...

Heathkit SB-303 Restoration

 This is a Heathkit SB-303 receiver I restored. To be 50+ years old, it was pretty well intact. I replaced the electrolytic caps, replaced a few out of spec resistors, replaced a bad transistor in the I.F. strip, replaced a bad hetrodyne osc crystal, serviced all controls and switches, and disassembled the vfo and serviced it (it had the typical vfo warbles). The 303 uses a batch of plug-in boards that will drive you nutty with bad connections, so I cleaned all those connections and shimmed the sockets a bit for a better connection when plugged in. Once all this was done, a full alignment really had her playing great! The paint was in pretty good condition, so I had some mixed to match and touched it up. Here's a few vids and pics of this restoration...
