Low B+ Voltage

[maxhifi]

What's the +135V supply feeding? The way that supply is designed, just using ohm's law there should be about 100mA through R185B. (275-135)/1360

If you're getting 60V, this means there's about 158mA - this is too much current, and you need to find out what's causing the extra loading.

You can use the voltage dropped across cathode resistors to figure out if a tube is drawing too much current. Keep in mind that if the TV is not adjusted properly as per the conditions the schematic's measurements were taken under, it may also affect the voltage readings.
