admiral 24c15 with 20b1 chassis attempt at restore

[fumplet]

still trying to wrap my head around how the focus circuit even works. I have positioned the focus coil just about everywhere now. back and forth got me the picture to go left or right, but it took me this long to notice it. the Focus tap on the rheostat goes directly to the power supply 5u4. Oddly enough if the 6v6 tube heaters fail, the focus goes out totally as seen when the 6v6 tube socket was intermittent. I guess I need to come up with a better way to clean tube sockets.
