I have 3 BeoCom 6000 Mk1 telephones that I would like to upgrade to Mk 2 with the 3455103 kit mentioned by Keith Saunders. I contacted my two local B & O dealers with the intention of purchasing the upgrade kits along with a new 6000 phone and PSTN unit. The first dealer( I have bought many items from them over a period of 20 years) informed me that the kit is not available and the second that they would not supply directly to me and the upgrade for each telephone would be an outrageous £240.
Does anyone know of a dealer who will supply the kits?
