Yours things are welcome here but there may be someone nearer you.
Let's give it a little time and see if someone else comes around.
The Beomaster 1200 will need a proper service;
New capacitors, trimmers, adjustments, potentiometer service etc. that's very common.
The speakers will probably benefit from new caps too. Capacitor kits exists,
The turntable however, if it works fine there's really not a lot to do.
Unless fitted with the ultra rare preamplifier (to fit a Beomaster TAPE input),
there are no electronics inside the Beogram so not really a lot that can go wrong.
