Yeah I hear you. That happened to me and led to a sudden breakdown. Fortunately I caught it before burning up the focus pot.
I am running the set right now and it is looking very good. I am finding the focus is more consistent and I think the focus drift was due to the failing transformer.
Cost of parts is about $20 do this.
Only real concern I have at the moment are the 450v electrolytic. When I switch on the set about a half hour ago, the voltage across them starts at 475v abd settles back to 450v where it is now. Tried looking for 500v electrolytics at Digikey and Newark and they are not available. Digikey had a 26 week lead time and you had to buy 1000 units! I have decided to put the capacitors in series as I want to put bleeder resistors in anyway
I am happy with result and will proceed with the proper construction of it to fit in the original can. It will in effect be a direct drop in replacement and feel ultimately will be more reliable that the the original transformer.
