Zenith 10s464

I am restoring this baby only promlem is the socket for the eye tube fell apart, is there a easy way to tell what wire belongs to what pin? they are color coded under the chasis , I figure I could re-install them by that? any help is appreciated.
Thanks

If you know how to read a schematic this will be no problem. Just look under the resources page here at nostalgia air, then trace the wires according to the schematic. good luck!

Hi

What Chad mentions is the best way to check wiring. Can't necessarily go by color code as there isn't always a standard.

To determine pin numbers, look at the bottom of the tube with large pins toward you. The large pin on the left is #1. Counting clockwise, 2, 3 etc until the other large pin #6.

Two large pins are filament. There will be 6 volts AC between these.

Pin #2 is plate. These is often a 1 meg resistor built into the socket, other end connected to pin #4.

Pin #3 is AVC. This lead will go to the radio AVC line. It should have high value resistors but little voltage.

Pin #4 connects to B+, around 250 volts. This will have a resistor back to pin #2.

Pin #5 will be near ground.

Thanks for your help, now just one more question, I need to align the beast, but cannot find this particular chasis in the resourses, it is a chasis 1005
is there a certain model I need to look at to make sure I know what padder is what?
Thanks again.

It's listed under the model number, 10-S-464.

Steve, yes I have the schematic, but that is all, is there another model that tells how to align the radio? under 10s464 it only shows the schematic.
