Re: Philips tuners in UK sets
Hi Fernseh,
post #8:
yes, most likely the 12nc refers to the complete assembly of tuner plus 4-button pre-set mechanics. Every "product" that left the factory required its own 12nc, and because this module was almost certainly pre-assembled while at Philips the code refers to the total unit. Which is supported by the code structure: 3122 108 60xxx was normally the 12nc for transistor tuner-only modules. The 3122 108 65xxx code suggest a higher level assembly. However, still a bit speculative, I need for data to confirm the latter assumption.

Yes, the AT7650 (alias NT5703, V5B) was widely used in many countries and for all standards. I'm currently updating the table, but essentially all Philips platforms in 1965-1967 used this tuner: 23TX500, 510, 520, 530, 540 and 560 and their German (TD) and French equivalents (they still used the old coding structure, so TF2366, TF2373 and TF2381). All other factories undoubtedly also used it. From 1967 they were used alongside the first transistor tuners, being replaced in new sets around 1968. Still working on the details, this will be part 3.
Cheers, Pieter
