Hello all,

Had a quick last look at the circuitry before removing the LOPT. With a 100pF cap for C99 (Tader C50) I still couldn't get a kink - but I think I did get higher EHT - well there was an arcing sound and sparkles on the picture with the trimmer all the way out!

Anyway I've removed the LOPT and made notes and pics of how to put it all back!

Questions arise though.

First, there's a perspex top to the LOPT holding the rings that go round the EY51 will that not distort if I cook it in the ovem

Second, Am I likely to completely knacker the LOPT like Chris if I cook this in the oven at say 57 degrees?

Third, how difficult is a rewind - does it require special equipment? - I'd be up for the challenge of a rebuild if all else fails!
