Hello all,
I'm recapping a Kadette 150 Cameo and I'm stumped on a cap value. It's showing a value on the side of the cap as 5. uF. (See pic) It also shows that same value on the schematic. (See pic) When I check the old cap with my LCR meter, it shows a value of approx. .0015 uF.
First off, The cap doesn't look right for either one of those values. It shows the one end as positive but I don't think that it's an electrolytic and I didn't think that regular caps came in that high of a value.
Unfortunately, there's no parts list that I can find to check it on.
If anyone could shed some light on this for me, I'd really appreciate it.
Thanks much,
Mike

For some reason I can't get the pic of the actual cap to post unless it does this time.

5mfd sounds right for a cathode bypass.
Probably 25 volts minimum.

Schematic shows 5 mf. Usually the value won't be that high but this cap also gives ground to the volume control. With a small value volume may not go down far enough.

International capacitor part number A-417 is...
5.0μF (microfarad). It can also be seen in Rider's page 8-1

Model 150 page 8-5

OK guys, thanks! The cap did say 35 Volts. I found a 4.7uF / 50 volt cap on Just Radios site. I assume that would work, correct?
Thanks again.

Yes, it would be the nearest modern value the original part probably had a very large tolerance rating as well.
