National TV-7W

[M3-SRT8]

Check out the 800v micas and resistors in the Hor Sweep & Synch circuits.

I replaced a bunch of resistors and the micas in mine. Pic is rock steady.

The step up transformer in the HV cage will take a while to "cook" to eliminate any moisture in it. HV will climb after that. Weak selenium rectifiers held mine back. OK after replaced by diode.

When you get audio back, be prepared for a loud sounding TV. They really crank.
