Doepfer

Thanks for getting back to me so quickly Dieter. 

That sounds the most likely thing to have happened, although I'm
always careful to turn the power off before connecting/disconnecting
the tanks. Is the replacement of the LM386 amp circuit just a matter
of swapping out the op-amp IC? Is it worth trying to see if that
solves the problem? Or is it a more complex operation? I just don't
want to be parted from the reverb for too long, as I'm based in the
UK, and sending to and from Germany takes time!

I'm guessing if I did short the RCA to ground, this isn't something
that would be covered by the warranty? 

Many thanks,

TJ
