I've decided to fix this thing up and sell it. It's going to take a couple hundred dollars to get it back into shape.
Things to be done:
- Serious cab cleaning
- Replace cab hardware (fasteners)
- Replace the speaker
- Serious chassis cleaning
- Replace two resistors
- Re-stuff the cathode caps
- Replace the filter cap can
- Replace missing knob
- Fix wiring problems
- New tubes
Haven't decided exactly what to do with the speaker. My options are to re-cone the original or replace it with an old one. The one I have has a LOT of corrosion on the basket that I'd have to clean up before the re-cone. But once done I'd have a like new speaker. It's easier to buy and old one, but it will have warts and a 50ish year old motor/cone. I'll come to a decision shortly.
Removed all components requiring replacement (caps & resistors) and finished cleaning the chassis & eyelet board. chassis cleaning is tedious! It requires patience, time and attention to detail. I started with a degreaser, small hobby paint brushes, and rages. Working around the components and wires is a trick. Also cleaned all the pots and tube socket pins. In the picture below you can see the missing caps & resistors.
I hate seeing old (vintage) amps where someone has gutted the factory components and replaced orange drops and MF resistors. Whenever possible I replace defective components with something as close to original as possible.
I opted to unpack the three cathode cap and re-stuff them with new Sprague caps. Once completed the amp will have new electrolytics, but still look like it's factory fresh. It's a bit of work but well worth it with collectable type amps. In the pictures below you can see the steps involved. The final step was to use shellac to touch-up the Mallory wrappers when the finish flaked off when I un-rolled the end.
