I have been doing some more checking on the chassis. I have found one of the chokes is not measuring as it is shown in the schematic. Part 120 is supposed to be 400 ohms but it is reading 3K. The part may not be original to the chassis as I see some sloppy soldering and cut wires that must have gone to the original one. I assume the 3K is going to cause a problem. Do I need to locate another one?

I also noticed ECaps 126 and 127 are 8MF wired in parallel. Can I just use one 16MF instead?

Mine was bad too.
I got a replacement off of ebay, a 32-7056N (not sure what the N means).
That's not the "same" part as the original is 32-7491.
However, I believe that if you look in parts catalogs for the specs you'll find they are the same.
The only "difference" is that leads exit differently.
One has both leads on one side and the other has them on opposite sides. (Don't recall which is which).

If you order one, be careful as I suspect it could be bad too.

I see two 32-7056 listed. One seems $$ and the other $$$.

Hi Greg, Thanks for the info. I might be better off getting a new Hammond one. They are both the one on top of the chassis. I need the 32-7491 filter and it mounts under the chassis.

Yes on the caps... 1x16 will be just fine. In either case just make sure the voltage rating is >= to the specified.
I just paralleled some 630V film caps for some of the other e-caps in mine.

I used a 32-7056 in place of the 32-7491. It fits in the place of the original.

Thanks Greg I was pretty sure it would be ok but you never know what the engineers are thinking.
