I believe I have found something

the signal going into pin 2 ( Sams got it wrong ) of V5 is hardly 6v PtP, should be 8.5, this is no doubt a cause of dim video,

signal going into pin one V4 point B is almost 5v PtP, I don't have another 6LF8 to try, I have one on the way, the one in there is also an original GE. it is obviously not working as it should be.
While I wait for the new one, I will check the resistors and caps around there as well.
Good thing that happened today is that the CRT socket came and is wired in, BAD thing is, the thermistor did NOT come, even though USPS SAYS that it did,,, they LIE.
