Admiral 20B1

This is the last to restore of 2 carloads of sets I picked up from captainmoody in the past year or so. Actually now I have all but a few of my sets working. My ratio is something like 25/30 restored and working.

Anyway, the Admiral came up with picture and buzzing, but no sound after just a recap and replacement of bad tubes. The only unusual problem was a broken 5U4 socket. I turned the discriminator transformer until sound came up with minimal buzzing. I'll go through the proper sound IF alignment tomorrow.

For a while I couldn't figure out why I had no picture on the right edge of the screen. I tried moving the ion trap and the focusing coil, but I couldn't quite get it. It turned out the whole assembly with the yoke/focus coil was actually a little off center.

In many scenes the retrace lines become visible, I might also try and add some retrace blanking to this.

I also have to clean some minor rust spots off the top of the chassis, and do some minor touch up to the cabinet. I have the knobs, but I'm missing the back, like most of these sets seem to be.
