Lecson FM1 Tnuer

Hi all,

I was emptying my loft over the weekend prior to a house move and came
across my old Lecson FM1 tuner. It's a match for the AC1/AP3 pre/power
amp combination that is better known, but it's the only one I've ever
seen. I no longer have the amps, but I would like to see if anyone
knows anything about the tuner, like how many were made, servicing
etc.

The tuner dial needs a new pot - but that aside it's functional
although probably needs a service and tune up.

thanks

Paul
