Matt -
OOPS! A correction on my part. If you remove the capacitor from the circuit you cannot wire the bell across T&R it has to go to a Common Bell connection off the KSU. I'm going to adjust my earlier post.
I'll have to look at the prints to get you the ringer info, but I would think off the top of my head that the Red & Black leads should go right to the B1/R1 leads in the KSU.
Ed - Jump in here at any time and correct me please.
