How to check voltages??

[DaveWM]

a tube stand off is nice for checking tube pin voltages.

B+ can be located, on some PCB types the sams will indicate where various B+ voltages can be taken off the pcb at test points.


both of the above can be done with the chassis in and everything hooked up.

I have found I can get to the pic tube pins by just pulling the socked off enough to allow a clip on a pin but still have the crt connected. I dont like to be probing around, incase something slips so I make sure I have a clip and nothing is shorted, then power up take a reading and power down to remove clips.
