Three ways to locate the heater pins of a CRT:
1.) try the 2 pins on either side of the key on the plastic center pin. those are the heater pins on most CRTs with a center plastic index pin.
2.) look at the neck PCB for solder pads under the socket with H next to them...Or on vacuum tube era sets without a neck board the brown and or black wires.
3.) google the CRT part number with the word "datasheet" included in the search string. The datasheet will give you the pinout...We can help you read the data sheet if you can't make sense of it.
I'll investigate your instructions and take photos if possible. This analysis of the CRT may prove to be above my current ability. I'll let you know what I can do. Thanks.
