I've checked over the set's power supply, and I keep going back to the multisection filter caps. They all test bad, using my Heathkit cap checker. Certainly the e-cap section that was tied into the video IF bias supply was bad enough to cause a 2 watt power resistor to burn up into two pieces. The primary filter cap in the 5y3's filament string had also belched its guts out as well. So for now, I would just say that the transformer was killed recently by someone who powered it up with bad caps. After all, the set's owner was given this set for free, so it is possible the previous owner toasted it, knew it was badly damaged and gave up on it.
This leaves me with looking for a replacement power supply. Here is how the 802's tf broke down:
The plates of the 5u4 and 5y3 are shared on a single center-tapped to ground secondary.
The low voltage windings go to the 5u4's plates and put out 270 volts.
The higher voltage windings go to the 5y3's plates, supplying 440 volts.
There are two 5v windings for the rectifier filaments.
There is a center-tapped winding dedicated to the two filaments related to the phono preamp tubes.
There are two more pairs of filament secondarys, these are not center tapped:
The first filament secondary supplies 8 tube filaments and the dial lamps. This is all for the radio.
The second supplies 13 tube filaments for the television tubes.
So, I suppose to find the current handling of this transformer, I need to sit down with my tube manual and add up all of the filament currents in each string? Do the same for the plate/screen currents for the rectifier plate windings?
