Hi all!

I recapped my BM the other week. I haven't yet adjusted the no-load current, but will do so whenever I find some time (and the weather goes bad). The BM stays pretty warm in standby, even though I rewired the trafo to 240V.

Yesterday I went and got myself one of those master-slave power cords to allow the BM to turn the other devices on and off. It turns out it doesn't work. The other units don't turn off. Now, my analysis is that the BM pulls about the same amount of current regardless of wether it's on or off. This would also explain why it's warm when in standby.

Now, to my question: Can this be caused by the no-load current being off? Or should I look for something else? A relay somewhere?

I should also say that when in standby I sometimes hear a relay clicking. Sometimes once, sometimes a few times with a few seconds to a few minutes in between. But I don't think I've heard this since the reacap.

Any thoughts?
Thanks!

Check the solder joints at the standby (amplifier power supply) relais, particularly the
ones for the activating coil.
Vibrations and general handling of the board/Beomaster related to the recap'ing etc. will have
pushed bad solder joints over the edge.

Martin, once again a sopt-on analysis and advice! Resoldered, and now it works!

Thanks a lot!
