A weird thing about this set is, the schematic shows the HV to be at 9k, which is the nominal voltage for a 10BP4, standard CRT for the RCA 630TS of which this is a clone of.
HV tests puts output at 10k at mid brightness.
However. FADA put in a 12LP4, and specs show that to have a nominal voltage of 11k.
Did they flub things a but to put this tube in?
It does work, but I can turn up the brightness to a point that it overloads the HV and blooms.
W/O a load, the FBT is putting out about 10.2k, this seems OK for one made for 9k. :O
