On going Zenith 25MC33 roundy restoration
I got this set at the ETF meet last weekend and was working on it here and there during sanity breaks during finals last week. At the meet I and another collector saw the old orange drops in it and assumed it had been restored which turned out not to be the case.
 I powered it up and got good sound but no HV. Well still assuming good caps I replaced nearly all the hroizontal/HV section tubes which were mostly bad anyway. The focus rect. tube was missing which I later found was for a reason. This landed me no net improvement. I then pulled the chassis, tested and replaced several caps in the horizontal section. This got me 11-15KV of HV, and a shrunken raster with pull-in on the sides. What caused that?, what else I had to fix?, and what is still not working?...All that in my next exciting post. Gotta run.
