Could you send a link for the K4POZ caps? I could not find it.....
I did find http://k4poz.com/ with stuff for sale, but no caps.
I am looking at changing to "Snap In" on my Ten Tec Titan and using the wd7s
oard to mount them.

I am also curious where John found the "Snap In" caps so cheap.....

K4POZ sells 390uF/450V 105deg on QTH.COM. I've bought many for amps
nd never had an issue. His are 2.50 each.

I am repairing an Alpha 87A and need 7 HV filter caps (350uF @ 450v)
screw terminal. The Alpha people spec for a Cornell Dubilier part
(CGS series) that costs $40-50 each at various sources. On the
other hand I can buy a different series (381LX) from Cornell
Dubilier that has 330uF @ 450v with very similar specs including
tolerance, temperature, ripple, DC leakage and ESR . These would
cost me $2 each. The expensive ones are 5" long screw and the
cheapo's are 1 and 3/4" snap-in. I think I can easily fabricate
small screw down double-sided copper thru-hole PCB adapter boards
for the snap in's ... Is there another factor between these two
electrolytic series that is not obvious in the Cornell Dubilier spec
sheets that should push me to the $300 set versus the $14 set???
