Hello AK'ers.
I'm working pm power supply, and i was wondering about some changes:
1.- can i replace the ceramic caps with films caps? Foto

Old one is the righ.

2.- the supply board has printed "1A 125V" on the fuses places. I actually can't find 125 v fuses. Can them be 250v instead?

Thanks You.

These look like the rectifier snubber caps to me. If that's the case, these should be replaced with X/Y rated safety caps (which in my experience are usually ceramic caps, and are clearly marked with the X/Y rating).

I have the same suspicions . . .

Why replace them? Ceramic caps like that are the most reliable components in the receiver. Should last forever unless physically damaged.

after 45+ years, i´d think to change them couldn´t be a bad idea. the replacement are inexpensive and the board is easy to work in.
