DuMont RA-103 Doghouse Horizontal Problems

[M3-SRT8]

Doing resistance checks on the 6K6GT Horizontal Oscillator (V21, per Sam's) and came up with open readings on Pins 3,4, and 6. They should read 6Kohms, 11Kohms, and 800 ohms, respectively. It is measured from Pin 8 of V27, the 5U4 LV Rectifier.

Also did resistance checks on 6AC7 Horizontal AFC (V20) and came up with open readings on pins 6 and 8. They should read 20Kohms and 23Kohms, respectively, and are also measured from Pin 8 of V27, 5U4 LV Rectifier.

The symptoms on the CRT is a bad smearing of the horizontal picture, and a stretching and cutting off of the left end of the picture. Unable to use L30, the Horizontal Output Trans, to restore the left side of the picture.

I replaced the Horizontal Sweep Coupling (C90, 1000pF, 500V), Horizontal Discharge (C89, 680pF, 500V), Phase Shifter (C84, 10000pF, 500V), and Horizontal Synch Coupling (C78, 47pF, 500V) (along with all new Tubulars and Lytics) because I've read how these Caps are frequently toast. I used new Silver Micas, all rated 500V.

What's amiss?

Thanks
