[Milsurplus] Mica capacitors?

[jwatkins]

Hi,

We do use the orange drops for recapping the R-390A.  Work great, and there
is room to put them in.  Wish I had known about the axial lead variety,
would have used them.  No modifications, just replacement of poor quality
(liable to fail) parts.  Especially the blocking cap for the mechanical
filter.

Cheers,

I concur Robert, anytime I see a replacement part that is obviously
new or otherwise out of place in an old piece of gear, I investigate
further. As you say, it's a clear indication that someone was in
there, most likely from a civilian standpoint.

SBE did make axial lead caps but they were smaller value or voltage as
I recall. They are about the size of a 5 watt carbon resistor. Still
have a bunch of them somewhere. But the vast majority use the same
equipment that the originals were built on, giving them more of a
radial style. Fortunately the leads are usually long enough to work.
The biggest issue I've had with them is making them fit in tight
places.

Recently SBE has developed a new type of cap used in electric vehicles
and it's really taking off. Good for them, because for a long time
they struggled to stay afloat.

I'll mention the color issue to Ed and see what he says. Never hurts to try.
