This is how I do it....
1]Remove speaker grille, and panel.
2]Get out permanent marker and mark a line on each of the yokes and crts to
realign.
3]Disconnect plug if necessary and loosen yoke.
4]Rotate yoke so solder/pins are directly facing me--slide up/down for
access.
5]Solder all pins.
6]Do all three yokes.
7] Realign starting with the green -use any news show that has the ticker
tape for alignment or a grid....or go out to the van and get the generator
for those rare/occasional UHF'ers.
8]Close it up, collect money, hope your day consists of nothing but cracked
yoke connections.
