AE 80 Ringer issue, Help please

[debeaune]

Have an AE 80 that has a weak/ bad ring.  It starts out loud and strong but quickly fades to a very light clap.  Is it the cap, it has a 47uf 50v, should I be using something else? Thanks, Tim

That is definitely not the correct capacitor to use.  A .47μF (non electrolytic) capacitor would be correct.  Is your ringer marked "SL"?

I think I see a screw on the clapper. Could be a frequency ringer.

Larry, is that a 47uF Non-Polarized Axial Electrolytic Capacitor you're saying I should use?

No, it should not be an electrolytic type and it should only be about one half (0.47) microfarads, not 47.

Compare with the info in this thread:  http://www.classicrotaryphones.com/forum/index.php?topic=10387.0

Think this one at Jemco will work then? .47 uF 100 Volt Mylar Capacitor Thank you.

A ringing capacitor should have a higher voltage rating.  Choose at least 200V or higher.   A standard ringing voltage for straight-line ringers is 90V, but frequency ringers used up to 160V or so.  See also http://www.classicrotaryphones.com/forum/index.php?topic=11938.msg126866#msg126866. Indeed it is hard to get a 66 Hz ringer to move with less than 100V.

Thank you, good info
