Quote from: TelePlay on August 14, 2016, 09:14:04 PMIt looks like this ringer box was used with a desk set and I don't have any idea of what would have been in the desk set to complement the ringer and it's two capacitors. It must have been a side tone set up unless their was an induction coil in the desk set.
QuoteI was surprised to find a 5 uF cap in the box. I would assume the 1 uF was for the ringer (the diagram on the door is hard to read) and the 5 uF was the talk circuit. Maybe the other way around. The wiring diagrams show two caps but don't put a value on one of them. Any thoughts on this? Rewiring from scratch will begin in a month or so and will most likely have questions then.

Quote from: TelePlay on August 21, 2016, 03:49:45 PMWith a 30x loupe, I was able to make out what was printed on the dark brown, lower condenser. It readsA.E. COCHICAGOM.F. 2 TYPE D-6891INSPECTED BY __________but it tests to 5.0 uF. Anyone have the specs for a D-6891?========================Ran across the second image in my bell box file. Maybe this is the reason no one else wanted to buy the ringer. That's what it looked like when received.
