Default Re: Kellogg wall phones - need help

Dags, thank you for drawing that schematic! That definitely helps!

I had another quick question - in general, how reliable are the capacitors in these old telephones? Should I replace it? When I've worked on antique radios, I usually had to replace several capacitors, especially electrolytic filtering ("smoothing") caps and wax ones. If I do replace the capacitor, I'll leave it installed for historical purposes and just clip the wires and put a new cap across them. But should I bother with that, or do you think the original capacitor might still work?

Oh, and I just tested the ringer. I hooked up one telephone to the other...when I cranked the first one, the bell rang on them both! So at least I'm getting there!
