I have a couple new pictures--from the set in the garage now. One shows it ON---I took a chance---all seemed ok. I gave it about 45 seconds or so for the tube to preheat--and then powered it on. The raster came on INSTANTLY, snow and white, (NO analog here in years ). I have a BIT of purity issue in the corner--but not bad--and likely easily remedied.
(the black bar in the oix is NOT really there--it must be some sort of shit with my phone--it is NOT there in person).
You have to admit....Zenith started a NICE, but short-lived trend--with the VRT magnetic regulation. For a few years...most mfg's used them, even in one chassis, RCA, (the ctc-74/81). Zenith even used the VRT in the first gen. of the system 3 chassis---but after that....the dreaded 9-160 module and it ALL went WAY downhill...after that.
I DO realize some here will remind me that actually DUMONT in the early 1950's, maybe late 1940's--used the Sola Voltage Regulating Transformer power supply--so Zenith did NOT use it first, but in a SS tv--they DID. They even used them in a few BW chassis sets, including the 19GB1.
