As to the channel difference that could just be a calibration issue and will get fixed when the tech goes over your machine.

The PR-99 were used for remote recording and for broadcast and proved to be very rugged and trustworthy under less than ideal circumstances. Best of luck!
Thanks very much for the info

My tech had a look at it on Friday, said it was just a loose connection. He's going to give it a proper clean and service over easter

He basically said the same as you, that the machine just needed a bit of TLC. As for the scratching/gurgling noise, he thinks the heads need demagnetizing.

Hopefully I'll have it back and working properly in a couple of weeks

Thanks again
