Yeah a picture of the chassis would help. I've recapped a few (k4900 med res) they are as simple as the regular chassis'. I'm sure there are others that are not as simple.
I fought my Narc medium res chassis for a month with flyback, hot, cap kit, resistors, etc. Finally I sent it to Chad at arcadecup and he fixed it right up. http://www.arcadecup.com/
Recapping, etc is easy. testing is hard if you don't have a tube/yoke that matches. That's why you need to identify your model. I offer repair on a few med-res, but not all.
And this would have been better asked in the Monitor section where the experts are...
