Vox Cambridge 30 breakdown

[Vincent]

Does anyone out there know why the clean channel on a Cambridge reverb 30 would distort?

In fact both the channels on mine have broken up. I think the problem is that they dont take kindly to being played at full whack too often. I wonder what component is responsible. tremolo is also gone. In good nick these sounded very good. Good tone-better I would say than Valve Reactor.

Hi,
My Cambridge has the same symptons. It distorts in both channels. I thought it could need a new valve (it uses a ECC83 in the preamp in Channel 2) but the fact that It also distorts in the clean (transistor) channel indicates that maybe the cause may be different.

Didier, my Cambridge had the optocoupler problem solved from the factory but it´s possible that the new one would be deteriorated too.

If it was replaced by the factory, may be that they used a component from the same supplier than the original one...

The one indicated by Jimbo is from another supplier, and supposed to be much more reliable.
