The 1973 and 1975 Trader indexes list a few Pye units of the right era that could be similar but I don't have sheets 3044, 3082, 3099 to confirm.

I think that I saw that on Facebook earlier: https://www.facebook.com/photo.php?fbid=964786686940344&set=pcb.10153058030596555&type=3&theater
For those who can't see it on there, I've attached one of the internal pictures... If that's the same thing, then I'd venture that it doesn't look like a Philips re-badge to me. Those big yellow caps were used by Hacker in their later sets, and the beige carbon-film resistors were a common site in many UK products at the time. The deep red ones are my favourite though  I could easily be wrong...
yes have asked. In lots of places can upload more internal pictures if anyone wants me to.

The light bodied resistors do look like Philips but the deep red ones look like Piher, a Spanish make, which I can't really see Philips using in place of their own product. But ... ... I bought Piher carbon film resistors for 16/- a hundred for several years from RTS, the spares and general component distribution arm of Pye before the takeover by Philips ... ... so could it be a very late Pye product designed/made before the acquisition ...?

Thanks - I couldn't remember how to spell Piher
 About the beige ones, there are two types: You have the ones that are the same diameter along their length, so you could be forgiven for assuming that they are carbon-comps. But in the flesh, you can clearly see the spiral cut into the film. I brought an ice-cream tub full of them from a university auction some 20+ years back, and I use them as reasonably sympathetic replacements in transistor radios. I'm not sure who makes them, but I'm pretty convinced that it's not Philips. Any ideas? (For clarity, I'm talking about the larger ones - e.g. see the pair of 1k resistors by the right-hand switch, next to the "P/U EARTH" print. Quad used them in their amplifiers, for what that's worth. Most of mine are the smaller version, but I do have a few in that size) The second type look more conventional, with the classic "dog bone" shape. Philips did make resistors that looked a bit like this - without digging them out, I'd have to say that they don't look quite the same as these one. I remember salvaging loads from their tape recorders and radios. This was at a time when most were still using carbon comps. Other components don't "feel" right to me. The mix of caps, for example. The IFTs. The trimmers. It reminds me a lot of late Hacker rather than Philips. Perhaps, as you suggest, it's late Pye - or perhaps early Philips (using up old stocks of components purchased before acquisition)? The timing is right - 1976 fits in with when Hacker started using the yellow CSA caps. Before then, Hacker went though a phase of almost exclusively using Philips electrolytics (Sovereign III era), and before that it was a goodly mix, including quite a few Japanese types. The earliest sets used the terrible blue "Daly" types, amongst others. Physically, it doesn't "feel" like Philips either - the layout of the PCBs, the design of the metalwork. Too conventional. But I could be wrong... Anyway, interesting stuff, but doesn't really help the OP. Could you describe the fault? It looks like reasonably straightforward circuitry, so a schematic might not be necessary...

had an odd half hour to look last night
board numbers Amp T2-AF-pp m k2 radio T2-RF-Dec-2P fault is not working on phono/ record deck I/p its ok if I place a finger on the I/ps on the amp board signal route cartridge -twin screened lead terminated to a 5 pin din -this plugs into 5 pin din on back, each channel has a resistor in series with signal lead there is also a cap in parallel with this resistor- signal then goes to tape I/p switch - then final ends up soldered to the pins of the phono I/p switch- then off through to the amp will check / clean the switch's first |
