I wonder if you could help please?
I have a Revox B250-s amplifier, which audio wise is fine,but it has developed a switch on thump!
The thump is only on the LH channel. The volume controls are incremental keys, and the thump occurs when the volume goes past a certain level and occurs again when the volume is reduced.
If I make sure the speakers are switched out when the amp is switched on, I then increase the volume just below the level where the thump occurs, unfortunately, this volume level is below my normal listening level.
Can anyone recommend a service engineer please? I am in the Birmingham area and I am aware of the two Revox UK service agents.
Mike
