The bright side of it is that while you were doing all that troubleshooting, your mind
was absorbing more and more information about the principles and practice of TV
receiver design!
Don't worry too much about things being warm in tube type equipment. You said at
some point that you had added a resistor somewhere to drop the voltage. If the
DC supply voltages (+264 and +132) are reasonably close to the values shown on
the schematic, then the power supply is probably operating correctly. If those
voltages are too high, then a small resistor in series with each of the two diodes
would be the right thing, making sure that those resistors are correctly installed
to prevent any kind of shorting.
Bye for now.
