Mike: without the non-polarized capacitor installed on the early powermaster output there is no sound.
When I install one or two of the 100 uf caps (in parallel) the sound comes on and stay on accordingly, however the bell comes on and most times I cannot get the bell off. and it usually triggers the announcements.
I'm still hoping we can find a fix to use these powermasters ( I need to power three different loops)
I hear the Legacy powermaster will do the trick but they are $99. each and not sure if that will do the trick
thanks for your reply
Tom
