Does anyone know what size speaker is in a MS-100 monitor? A remote site says theirs is blown. I realize it's just as likely that the power amp IC is gone but also don't know what was used there.

I don't know exactly what size speaker those monitors have, and they are fairly trouble-free.
I've only had to repair one twice. (not the same one!) Both times the unit was putting out
raspy, distorted sound, similar to a 'blown speaker' But both times, the speaker was OK.
In the 1st instance, it was a bad amp chip. I was able to find a generic replacement amp
IC at Radio Shack, and as far as I know, that unit is still functioning fine today.
In the 2nd instance, it turned out to be a power supply problem. Sound was "OK" at
lower volume, but at high volume or loud peaks, there was severe distortion. Another
trip to a nearby Radio Shack to get a couple of replacement capacitors fixed it just fine.
(and I really miss Radio Shack & Fry's Electronics for stuff like this!)Last edited by Jim Cassedy; 10-04-2022, 12:51 PM. -
It was a full range JBL speaker. Usually it is the contacts of the IC that have issues or the pot or selector switchComment
