First, thanks for all the input. I started checking all of your ideas and finally figured out PART of my problem.
R174 is a big candohm in the focus circuit. The old one measures 3000 ohms which is what I ordered in a 50W power resistor. I failed to note that it has a GROUNDED CENTERTAP. That's why hooking the old one back up with jumper wires on the ends did not solve the problem. Hooking it back up with the center tap grounded gives me the correct B+ to some of the circuits. However, now the other candohm R178 starts frying. I had used a 10W 1650 ohm resistor for it. Maybe I used too small a wattage.

Before I order correct power resistors, what would be a good wattage to replace the old candohms?

The schematic I have IS the one on the ETF site. However it's confusing compared to my set.
