Re the audio: seems to be an interruption of the af after takeoff, evidence by the slight hum you're experiencing. So start by making certain you've replaced all paper caps before proceeding. I'm presuming you are getting a video signal to the CRT right now???
Remember, the Pilot TV37 is the Smart Car of early television. Don't expect quality-anywhere-and proceed accordingly. Once you get it working correctly you'll have actually good audio, and a decent picture if viewed thru a magnifying glass and a Scotch (or two) handy.

hey George yes it's been completely recapped including resistors and I got the audio working I figured it out and I have a perfect picture but what I'm left will is the vert size is maxed and won't fill the bottom half inch of the screen but 3 caps were put in that are nos, big mistake because they test good but sometimes under load they may change value so that's next for me to check. I get the reason for inrush protection because of the crt heater but this one the heater don't come on fast upon turn on so maybe something was put in already to protect it I don't know I didn't check it. Do you know the voltage or info on what zener to use to protect the heater, and does this Zener go across the heater feed wires. This zener is the glass diode IIRC .
