Overcome with the thrill of success i had the guts back in the cabinet so quick onlly to have it flat line on me the next day.
Got this one up and running in little time only to flat line.
No vertical sweep so i checked the plate voltage on the vertical output
tube (12AU7) i'm missing the 390 volts, Oh crap! according the schematic
the only path for the 390 volts is the primary of T402 the vertical output
transformer seen in the foreground. To my amazement i tried a transformer
from a scrap Admiral (24A12X), fastening it to the chasis with two screws going through side vents. Ugly yes but it works.
The original has 700 ohm pri /12 ohm sec and the one i put in is 500 ohms pri / 9 ohms sec and despite all of that i took very little to set up the vertical
height and linaritey. I would like to find an original transformer part #79B24-1,Simular 20Y1 chasis
Another avenue of hope is a audio output transformer i saw in a parts catalog one with 600 ohm pri / 8 ohm sec and of course designed to handle plate voltage.
