Preidcta Holiday CRT testing

[N2IXK]

The tube number is usually on a paper label stuck to the side of the funnel shaped part of the bulb. It is somewhat common for it to have fallen off and be laying loose inside the shroud.

As far as the couplates go, I would recommend replacing them while you have the PCB out. They are cheap enough to rebuild/replace, and saves all the work of pulling the board again. I believe Bob Andersen (bandersenTV) sells reproduction units already built.

Another common trouble spot on these sets are the tube sockets on the board. They are prone to cracking of the metal contacts, resulting in intermittent operation or outright failure. Check them carefully while the board is out and replace if needed.
