OK lets get this fixed. Manual is in hand.......
First this does NOT have the 3 identical resistors. They
are built into the resistor package. The 3 outputs should read
abt 175 VDC on the C ( K of CRT ).
Rule is with in-line CRT the lower the K volts the brighter the pix.
Check pin 2 of U1202 ( long resistor pack) should be abt 230 VDC.
Check wiper of G-2 should be abt 500 VDC. Be SURE your meter
is safe at that voltage ! If its high check R1214 ( 1.8 meg carbon )
off one end of the G-2 control.
good luck
