oK Thanks, although I already have it now from when you posted the link to it earlier in the thread, the only problem with it is that the schematic is divided up between 4 pages and because of that its hard for me to figure out where the various B+ voltage values are for the tv so I can try and figure out whether or not the TV's B+ Voltages are lower than they should be which if they are it would point to some bad power supply caps and or a bad selenium rectifier (which either way I would have to replace either one of them).

Do you have a Printer? If so print it out and tape the schematic parts together.
The schematic shows 140 and 145 volt sources from the power supply, checking the plate voltage at the Damper or the Audio Output tube should tell you if they are working since one is fed from the 140 and the other the 145.

yes I do have a printer, I'll see if I can print out the service manual and just set the parts of the schematic next to each other in their respective order and see if I can make any sense of it that way.
