repair of an ICF-PRO80
similar to the ICF-PRO70

English below
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

All photos show the device with the original capacitors, except the last one, where I replaced them. Just compare the 2nd and the last photo. There are 3 Cs replaced on the bottom right, an five on the bottom left. Matthia

Thanks for the photos. I have no sound, not even a weak one. I was told the the transformers are burnt out. Can you confirm that and if so, which ones are they or where are they located. Thank you in advance. Regards, nyjahan.

Cap Question
I was just given a Pro-80 for free. It has no sound but all other functions work. By no sound I mean no static and no beeps when I push the keypad digits. I think I see that you replaced some of the SM's with radial caps. Is that correct in what I see? I am going to try to do a recap on mine but SM's I have never done. Also, I can't find a service manual or schematic on line. Can you help with a schematic at least?

Thank you for the information on how to fix the Sony ICF-PRO80. I have just fixed my PRO80 and it works like new. I replaced all the capacitors with the same values (uF) but with higher volts, this makes them bigger. I just put them all on there sides, I was then able to reasseble the receiver. If you cannot find the same size of capacitors just make sure you get the same or higher voltage and it will work perfectly. Thanks again

My Sony ICF-PRO80 slowly-slowly lost audio. At the and there was no audio. I found this site and i replace all the electrolitic capacitors on the cards "PLL Board" and "Signal Board". Now audio condition became very good. But, only with mode "Narrov FM" with the other reception modes there is no audio. What can i do? Anybody can help me? Thank you. // 2012-01-19 Kemal GÖZEN

Replace ALL the smd-like electrolyt capasitors (14-15 if i remember right). Even if You get the sound back by only replace the capasitors related to the PA,the reminding ones still make trouble; they leak out op PCB which cause your radio to mailfunction, or in worst case destroy print, coils or nearby components later.
