1954 Philco high b+ issue.....

you use two 9v connected in series, with the middle connected to the chassis ground, Then you connect the + to one side of a 500k pot (or what ever you have handy) and the - to the other side of the pot, then use the wiper as the AGC, that way you can swing from +9v to -9v relative to ground with the pot.

you can check you setup by using a meter, connect DC neg to ground (center connection of two 9v batteries) and pos to wiper. with the wiper centered you should see 0v moving off center will swing + or -

FYI i had a set that had lots of probs with sync, I thought it was alignment, turned out it was an open .15 cap on the AGC. You nver want to go to alignment unless you are sure it needs it and you have the correct equipment to do it, and even then it takes practice to do it right. Rarely is alignment bad enough to cause really bad problems, you can generally improve a pic some but honestly unless someone has gone in and done "screwdriver drift" its prob not going to be a problem.

other considerations on sync, of vert is ok and horz is not or if horz is ok and vert is not, then its prob not the separator but rather the integrator (vert) or something in the horz osc that is messed up. when they are both out you can assume its the sync signal. then you just have to figure is it the signal to the separator or the separator itself.
