Have you cleaned the LASER head by hand (not one of those CD cleaners
you play in the drive)? It is possible a very thin film over years is
clouding it making tracking harder.

How would that affect the sound from the phono outputs but not the
balanced ones?

Ar seems to have been offering a solution to Brian's problem, not yours.

As for your problem, you say the levels are normal, but there's an HF
loss on two of the outputs?

That's about it. Severe HF loss. I'm thinking it may be down to the muting
circuits being partially activated. They are electronic on the two that
are affected - but a relay on the balanced ones. So it is either on or off.

It's possibly too obvious, but have you checked the 680R resistors for
high values and any capacitors for shorts? Or even a leaky connection/
switch on the switching inputs?

I've found a circuit online, but they want me to pay for it....
