Loewe Legro Ta (Linn Majik) Err1 Problem

[iggythebrush]

Hello, I wonder if there is anyone oout there who has info about the Loewe Legro system?

I have inherited a Legro TA, which was a rebadged Majik with Sneaky piggyback tuner board.

When I switch it on, I get an "Err1" in the display, with what appear to be hex numbers displayed when the keys are pressed.

I have searched for all obvious faults such as PSU problems, blown monolithic amp ICs, etc, all to no avail.

Does anyone have any other ideas, or know how to decode the error display, or even have a schematic of the beast?

Thanks
Ilya
