Hi

I just sold my A-126 frequency shifter to a list member only to discover 
that it doesn't work anymore! The audio in and out work as normal but 
there is no signal at the shifted outputs.

It was fine a few weeks ago and I am pretty sure nothing like reversed 
power could have happened - but what else could cause this? Seems like 
the internal VCO is probably kaput?

any ideas?
