Sam -
I've got most of the trimline done, and A & A1 control is functional (I've not yet connected it to the KSU, but it checks out with my ohmmeter).
One problem though - I couldn't rewire the ringer as instructed - here is what I've got coming from the ringer:
Black - L1
Red - Destination terminal unlabeled, but it's the other end of the capacitor (i.e. the end that does not have the strap on it).
Gray/Red - Unused
Gray - B
There is also some faint noise on the receiver when the switch hook is held down... could this be related to the as of yet undone bell rewiring?
Thanks!
Matt
