73 Zenith Chromacolor II no picture

The tripler is connected to the output from the flyback transformer, I believe it is on the horizontal part of the chassis which is located behind the mani vertical part of the chassis. You might have to loosen the chassis mounting bolts and pull the chassis back to see it...Arcing in the crt neck either means a bad CRT or that the crt is not grounded properly. Make sure the grounding straps to the crt degaussing shield, picture tube socket and chassis are all connected.

Also it seems like if the focus voltage is missing but the HV is there, there could be arcing...this might be caused by the tripler.
