One of the 'balanced input' channels on my pre-amp has totally failed. The other channel works perfectly, and the three 'line level' inputs all work fine.
I am not sure how to work out how I can repair this.
There are a couple of SSM2141 chips near the balanced input. Could it be that one of these has died?
Thanks,
George

There are two SSM2141 IC next to each other.
Measuring the DC voltage from ground (on the case) to Pin 6:
Left channel: 0V
Right channel: -13V
So, on the right channel we seem to have nearly the same voltage on pin 6 (output) as on pin 4 (-Vee). Pin 6 is -13V and pin 4 is -14.5V
Does this mean that the SSM2141 chip is kaput and needs replacing?

It worked!!!
I replaced the SSM2141 chip with a new one from Farnell. My Linn RoomAmp is working perfectly.
I am dead chuffed as this was not an expensive piece of kit new. Okay, it do not cost me much at all, but it is really great to have kept it out of the bin.
Thanks all for your help,
