yoke problem
Thanks to all who replied. Yes, this set was on Ebay recently. I know I paid way too much for it but I had been wanting one of these for a long time and don't see them for sale everyday. It turns out the original owner played for the New York Highlanders/Yankees in 1912 and then became a rather famous chiropractor. At least it has an interesting history! Anyway, after recapping it and checking all resistors and replacing any that were out of tolerance I applied power and found I have a short on the B+ line. It turned out to be a short (10 ohms) between the horizontal winding in the yoke and ground. So either I have to figure out how to rewind this strange thing or find a replacement. Does anyone have a good yoke you want to sell?

Phil, here's a link to the roster of the 1912 Highlanders. Which guy is he?

Update!
After removing the yoke from the contraption to which it is mounted I was able to see the problem. The iron wire had broken and some of it became unwound and dropped down onto a terminal strip below. Since it is grounded this created a short. I had and have no clear idea what this iron wire is for in the first place but decided to simply wind it back as best I could, cover it with electrical tape to hold it in place and see if that would work.
! As soon as it warmed up I was greeted with a sharply focused, in sync picture. I let it run for some time and the yoke only became slightly warm, as normal, so apparently my crude fix is ok. To answer some other remarks/questions: I have an envelope with the original operating instructions mailed May of '49 to George P. Shears, DC. in Huntingburg, IN. Also a receipt for tuner repair in 1952 from a shop in Louisville, KY. (They charged him $8.00) http://billbahan.org/dr-george-shears-dc/ |

Yep, ol' George had a cup of coffee with the Highlanders in 1912.
