On that set the B+ is normal at about 123-125V. The B+ is controlled by
yhe circuit on pin 5, some models have a pot to adj B+ and some use
fixed value resistors. I find on that set that the HOT tends to run
extra warm sometimes and that if you reduce the B+ to the point where
you just have sufficent width the HOT will run a several degrees cooler,
most sets aroud 115 to 118V. Easy to do on the models with B+ pot, on
the ones with fixed reistors just change the value slightly. Eliminates
the chance of it coming back with bad HOT. Also as normal resolder the
horz driver area and always replace the 1uf 160v cap there.
