CTC-15 restoration

hmmm

plate voltage is off, should be around 320v as should be the K G1 should be around 200v. You have about a 130v neg bias vers about 120v. which is not much. don't think that would cut it off.

I would check the brigtness control and make sure its working properly. as you need to get a handle on the odd plate voltage. Make sure you are reading with no signal. I like to use a VTVM for testing voltages, although a DMM would be fine, just not a VOM.

Pin 2 of the blanker should be -95v.

Make sure you have about 5kv of focus voltage. If the focus voltage is too the CRT will be dark.
