Mein SONY ICF-PRO80 hatte das Problem, dass Lautsprecher und Kopfhörer nur extrem leise zu hören waren. Hier beschreibe ich kurz meine erfolgreiche Reparatur.

The speaker and headphone output of my SONY ICF-PRO80 were very very silent. Here I describe how I successfully repaired it.
A snap of the disassembled ICF-PRO80:

A snap of the amplifier board:

Some of the capacitors leaked a bit:

I decided to replace most of the caps, they seem to be really bad, as the volume increased on most of the capacitors I replaced.
Amp-board with the replaced caps:

I replaced
4x 47uF/6.3V
2x 47uF/16V
1x 220uF/16V
1x 470uF/10V
You may also get your Sony ICF-70/80 fixed here.
Here's a short description on the ICF PRO 80.
