awesome! cant wait to get it running properly!

The ink stamp inside the chassis is somewhat smudged, but it looks like it reads "T211066". which would mean technician #21 completed wiring the chassis in Oct, 1966.

I’d be interested to see how you address the power cable and voltage selector if you plan to bring it up to spec. I used one of these on a recent album I did. They are really awesome for bass guitar.

[@YeatzeeGuitar]

Nice! TBD, ideally obviously we'd redo the 3 prong to have a chassis ground with the earth connection longer than the others and so on.

You say there is no reason to not change those filter caps, but Steven Fryette would disagree. He makes a good point that if the cap still works and is in spec, why change it?

[@YeatzeeGuitar]

1 had already been swapped poorly, there is zero advantage to keeping the other originals and just swapping the one. You don't know if the caps still work either, owner told me it developed a hum which is a often sure fire sign of filter caps going. There is no tonal advantage to leaving those power section caps, only risk.

@@YeatzeeGuitar Have you ever tried reforming caps?

[@YeatzeeGuitar]

For every one person that claims that's a thing, there are 5 that say it's not 🤷‍♂️

[@middle_pickup]

​@@YeatzeeGuitar People don't believe that old caps can be reformed? I'm not an electrical engineer, but I think the people who are have it figured out. Maybe this will help. kzbin.info/www/bejne/r4KtnpyXnJ6Hl9E
