Tom C, you have a good eye ! I take it with me to shows and or record shops to check out the merchandise.
Meanwhile I removed the CRT board cover to double check filament on CRT and to my surprise it was good! Now I haven't messed with this set for awhile and I know I triple checked the crt. I checked the filament supply pins 5&6 on the 17 pin cable and it was open. (feeds crt and video amp tube on crt board.) Well after eliminating the other tubes I removed the Umbilical cord from the rear of the chassis and pin 6 on the cable had broken off creating an open so I ran a new wire outside of the cable and she came back to life. Picture tube appears weak (don't have a crt tester). So after it cooked for awhile it got a little brighter so I went for the gusto and sent a signal from the BT modulator and got picture and sound ! Not very good but its a start.
Vertical started to roll within minutes, so now I'll proceed with the usual cap and resistor change. I have a spare pc board from a holiday and I notice there are some differences from the tandem.
Will it work ? I figured I would ask the experts first.
Excuse the long reply and lousy photo and thanks for all the input.
