Beomaster 8000 CPU

4 replies

I did a rebuild and recap on my old beomaster and i was wondering if anyone repairs or has parts for the control board... the amp works all cleaned etc... BUT BUT BUT the radio  dial shows the frequency and i can hear it skip past frequencies. I think the IC is fried bo840239s. It had issues many before  I cleaned it. intermittent front panel working etc. Still not working all contacts are checked.

It there another IC that controls the channel control

Is it a lost cause ?

It is a Beomaster 8000

 

Hi,

There are quite a few Beomaster 8000 restoration posts here on the Beoworld Workbench forum and on the Beolover Blog. Those will show you the scope of work typically required to restore them. They take a lot of work. The two microcomputer ICs on the Microcomputer board rarely fail unless someone damaged them. I would suspect them last regarding your problems. Faulting connections with solder joints on the board traces and cables are the most common source of problems.
