Sony ICF-7800 speaker repair: any replacement known ?
Hi,
I put a hand on five ICF-7800. After cleaning the AM/FM switch they seem to work pretty well despite distorsion due to the speaker suspension which disintegrated over the years. Is there a known repair for this, either a replacement suspension or a compatible speaker ? Thanks in advance. |

Round cone? size? Foam suspension kits are available for round cones.
A picture is worth a thousand words. |

The Roberts RC818 also uses a similar foam edge suspension loudspeaker. It is a 3" round unit with a shallow profile. Spares were available but are not shown on the Roberts Radio spares drop down menue but a telephone call to them would confirm availability.
I am sure that you have checked out the part number 1-520-598-0, now 9-910-99-31, which will identify current availability but just in case you haven't, there are 48 other Sony radios which are listed using the same loudspeaker. There is a SONY XDR X1DBP loudspeaker on eBay which also has foam suspension but you will need to verify suitability. Good luck. Last edited by simpsons; 10th Jan 2019 at 12:59 am.

The Sony equivalent parts list does not tell the whole story. Looking at the service manual, courtesy of electrotanya, the ICF5800 loudspeaker is held by a cusion within the case around the large magnet whilst the equivalant part, when used, has a small magnet and is secured by the cabinet at the front in the usual way. To cut a long story short, I have found the equivalent used part in my store, with a foam surround, but you will need to fix it in the case. The part you can have FOC just p&p needed. Should this help you, please advise and I will PM a photo and details. Regards Chris |
