I want to replace the caps, all the paper caps look original & I can read the values. The electrolytics look more modern, they are 47uf-160. I can't tell from the schematic if this the right ones. Is 47uf right?

Hi Tex

I can see why you are having a hard time reading the values. Just black blobs on the print.

Use 47 mf @ 160 volts for replacement. In this circuit it was common to use 30, 40, 50 and 60 mf @ 150 volts. 47 mf @ 160 volts will replace any of these.

Looks like 40@200 to me, but it isn't real critical. Norm's 47@160 will probably work fine and last a long time.

I have a CD of the Riders schematics, which is clearer for this set than the scan here at Nostalgiaair.

The filters, C10 and C11, are both shown on the parts list as 40uF, 150v. They were originally a dual cap.

But, as Norm says, 47-uF should be fine, indeed. But, I have a hunch that the 47-uF replacement caps that you found in the set may be OK. The 47-uF size suggests to me a fairly modern vintage?
