Hi all,

I have serviced this Beomaster and changed all old caps and tantalums two years ago. Now the machine has developed an odd problem.

When I power it on, no issue. It plays well and the sound is nice. But after some time the sound output will slowly drop to almost nothing. Very faint (but output still responds to volume control). It happens on both channels.

If I power down the machine and let it ‘cool’ for some time and power it on then the sound is back. But it will also die down very quickly. When I let it cool for a night it will play well for some 20 minutes and then the sound will drop again.

I am wondering what is the most common cause of this issue that affects both channels.

Many thanks for your thoughts,

Bert
