My latest project is a Zenith 8s359 that belongs to a fellow in town. I volunteered to help him get it playing. Hopefully it will all come together! He had previously done the cabinet so I’ll just be working on the chassis.

He said it had been working when he got it from his Aunt but no longer is. All but one of the tubes test OK, though I haven’t tested the 6U5. There are a few threads about this set on ARF and they talk about the rectifier 6X5 being prone to problems and taking out the transformer if it shorts. The dial string and dial belt are both broken and will need repair. I also read a thread on the Phorum about repairing the tone or station switches and it sounds like a difficult job. Parts are ordered, clean up has begun. Should be fun!
