" E " waste find

[radio nut]

Ok, Got the set and put it on a variac and powered it up slowly.

In my town we have two stations that still broadcast analog. picked up both but not crystal clear.

So far all of the tubes I have checked are sears and good except for the high voltage rectifier which was solid state.

The crt tests good no shorts/gas at blue 800 green 800 red 780.

The brightness is all the way up but witha good crt I am not worried. I will get a sams now and go to work.

What is the "killer" adjustment for?
