Hi Dave,
Do you also have the 120 volt power cord?
About your 40+ year old FT-101 high voltage capacitors. You should replace the two main high voltage capacitors on a 40+ year old FT-101. See eBay item https://www.ebay.com/itm/254527364032?hash=item3b43035bc0:g:CDoAAOSwyWheWysT (I have nothing to do with the seller). If they fail they can take out the power transformer.
It's also a good idea to change out C13, the 80pf@ 1kv driver to final coupling capacitor.? Also C11 a 200pf @ 1kv in the driver plate circuit? Bad things can happen if C13 shorts.
If you have scratchy controls and switches. The first thing I do with a radio that has been stored for a long time is exercise all of the front switches (especially the band switch) and pots end to end. Sometimes as high as 40 times each with the power off. Then I check to see what is still noisy and go from there. Most people like the Deoxit brand for cleaning switches and pots. Use care on the band switch - I use a toothpick and apply only to the contacts.
