philips: Dating the PS6 and variiations

The Philips Service Notes Supplementary Sheets (uploaded to the Schematic data base) indicates that the PS6 Service Notes for the PS6 were issued in October 1965 and for the PS6/01 in October 1966. One of the Supplementary Sheets uploaded covers a new Audio Module with a mix of Germanium and Silicon transistors. That sheet was issued in July 1967.

The sequence thus appears:

October 1965 PS6

October 1966 PS6/01 with Audio Module UA403

July 1967 PS6/01 with a BC108 in the Audio Module UA411 (TR101 = BC108)

There is also a change referred to in the speaker, to an MSP 2.75JB/33 This is referenced in the July 1967 Service Sheet as "Independent of the Module Change......"

Later, but undated, the RF/IF module changes from an UF302 to UF312
