B&O Parts - Beomaster 1900

Hi Guys/Gals

Am really struggling to find replacement slide pots for a mint condition Beomaster 1900 - need the Bass, Treble & Balance pots - originally made by Ruwido ( 20k linear for bass and balance, 50k for treble - I think) - anyone got any ideas.

PS Have the full wiring diagram and original semiconductor parts list for this unit if anyone interested - can do a pdf.

Regards
Terry
