Beomaster 6000 (Type 2251) – Standby Running Warm

[Ary]

Hello fellow BeoWorlders,

I’ve got a bit of a puzzle with my Beomaster 6000 (Type 2251). It has been running flawlessly ever since I recapped it with high-quality capacitors from Danish Sound Parts (formerly Beoparts). However, I recently noticed that it’s running noticeably warm in standby, which it never did before, at least not in a way that I would notice. Its not hot hot but like 36 degrees C. when its running it gets hot but I can hold my hand on it for a long time without burning myself.

The trimpots on the amp board are dialed in to service manual specs, so I’m wondering what could be drawing current unexpectedly. Before I dive in and tear everything apart, I’d love to hear some thoughts from you all.

I’ve attached a picture of the relay next to the transformer. It clicks on and off as expected, but there’s some suspicious white residue inside—anyone know if that’s normal or a red flag?

And I noticed that R12 (R1 and 12 are confusingly close together) gets  hot like hot hot like auwy finger hot…. hm?

Appreciate any insights!

Cheers,

Ary

If the relay contacts have welded, the amplifier section will be powered at all times.
I suggest you check if you have power to the amp section (f.e. by checking if idle currents are present in standby).
If you do, replace the relay.
