Powering a chassis with tube/yoke off.

[Daave]

I did post this in my other thread, but not sure anyone is reading it anymore, so this is sorta a double post.

I have the chassis on the bench and was wondering how to power it up with no anode connected or yoke connected. Can this be done?

I wanted to take a poke around at b+ voltages and other readings as well as learn to take readings with this oscilloscope I picked up, and compare to the schematic.

On another note the schematic contains many scope images but not really clear on when to take them (signal applied?).. I was going to try to figure out how to inject a composite signal into the TV to figure out why it wouldn't tune a colour picture.

Any info is great! Thanks!
