A combo stain is something that happens when you pull up to the house with another one. Yes I know its spam.

slow cooking on the variac, HOT pulled, VOT pulled, about 40vac. current nice and low so at least no shorts, filaments can bee seen glowing so at least that is working. filter cans staying cool. will ramp up a bit more later and then try a full power startup and see how it goes.

at first the HV would not come up, so wiggled some tubes, then tried again, ah the nice cracking sound. Hooked up the converter box, Rockford comes on (the worst episode ever, "just a couple of guys". Horz not right so adj and it locks in (weak lock and some phasing issues when on freq). Vert is solid. Color lock is weak as well (makes since if the horz is acting up, if I understand how it works a pulse of the fly gates the burst amp off and on, so if that is a bit out of whack the burst amp could be wacked.

it would be all b&W, (adj fine tune to just eliminate the 920kz beat freq) then rainbowing then color lock but again weak.

Picture was narrow as well, but that maybe the variac I am using, its not my heavy duty one (it has a built in isolation transformer and its metered for VAC and current). So I just try full line voltage later. If that does not increase the width I will need to do some B+ checking etc...

But for now its promising. I will prob pull the chassis after the full powr check out and go over it, I know there will be some caps I want to replace at the very least the horz coupling to the HOT and some of those high voltage ceramic tube paper caps in the vert circuit. I will install a B+ fuse and a fuse to the HOT like I did on the CTC-16. Will of course check all the filter caps.

The Vert looked very good, no spreading of lines and height and lin looked fine. I will still replace at least the lytic on the vert cathode bypass, its one of the paper wrapped metal tube types. Its easy so may as well get to it.

before powering it up I did check the HV tubes and the horz osc tube, all checked fine. while the chassis is out I will of course go thru all the tubes and clean the sockets and pins.
