Here’s a Zachry D250 solid state amplifier. It stopped working producing only a 100Hz noise. Look at them blue filter caps, seems a bit swollen.

Here’s a picture from the bottom of the caps.

Those caps are out of date. Had a hard time finding 15000uF 63V caps with a diameter of 35mm. Finaly found and ordered F&T :s with the right values but a diameter of 40mm. I should be able to fit hem.
