Picked up and Admiral 20X122

[Doug66]

SUCCESS!!!!!!!!!!

It was a dirty vertical hold control. Man, do I feel stupid that it was something that basic that I thought I had cleaned when I 1st started restoration.

I've got to get everything tweeked and make a decision if I want to put the modification on to eliminate the retrace lines.

Once I get it back in the cabinet, I'll post more pics.
Thanks again for all the help.

After a couple of forehead-slap experiences like that, I put cleaning of tube pins & sockets, plus all controls, at the very beginning of every project's to-do list.

To hopefully make you feel better, I worked on an Admiral 26R12, the exact type of set I had as a kid; first set. It was working fine after replacing all of the paper and electrolytic capacitors. Whilst still on the bench, I heard a loud snap/pop and was unable to locate where it came from. My vertical linearity was now a mess. The height control also had no effect on the picture (glaring clue that I unfortunately didn't pick up on).

Long story short, tin whisker on the height control most likely. Adjusting the control did nothing to the voltage. I cleaned if off with a brush and all was now fixed.

So, all that I can say is, "Welcome to the club".

Here it is back together in the cabinet.
Thanks for all the help. This one has been a learning experience for me.

Nice job. It looks great. It's one of those sets that I would recommend for someone who only wanted one vintage TV. A great performer and one of the the coolest looking artifacts of the '40's!
