Question:
I've had OSCON or AlumPoly type capacitors recommended to me
in a solid state amp, in place of Non-Polar/Bi Polar caps that were
originally used in the device.
It's a medium power standard amp made by Carver.
The location is along the center rail where it branches to each
channels first feed to the differential pairs output base then through
a resistors follow by by CapResistor filter then down to another
differential pair regulating the protection relay.
When I started looking into the leakage of these AlumPoly caps,
they are leaky! I mean this really isn't something I want is it?
Let me scan a page from the Schematic that shows where it is.
I typically would use a Nichicon Bi-Polar cap for these, instead of
an AlumPoly NPCAP PSG Series.
Yes, they have great endurance 15K-20K hours AND 500uA leakage.
Here is a link to the schematic LINK
see page six.
or better yet, here is a cut down version of the schematic.
What do you think?
Cheers,
