Hi,

I recently picked up a beige Apple IIe, which appeared to work but after 10 seconds the PSU started to give out a loud sizzling sound - the computer continued to work.

Open up the PSU case, and I believe the smell/culprit is two "paper line filter capacitors":

- 0,1 uF 250V looks the worst, very cracked and bulging metal sides

- 0.47 uF ? assume 250V ? looks intact, but best to replace

See here for a pic I found of the culprits:

... where can I obtain replacements from? I'm unable to source them, my electronics knowledge is lacking here. As a sidenote, the capacitors look "OK" on the PSU.

Thanks

JB
