The Large cap (0.1 + 0.1) tested fine at 3kV so I decided to leave it be - here's hoping!
I had a rubber stamp made with the correct script for the focus cap (it's a pity that it's hidden) but it is very easy to mess the print up and then it could be a re-paint job so I modified a mini-drill press to do the job but there was so much lateral play that I had to scrap that idea!
Next is to fit the focus cap, try to straighten the EHT enclosure and get on with the TRF. That one will be a problem if I can't get the metalwork clean enough. No way will I dimantle that one - well, maybe just the tagboard
