It would be interesting to know if Philips Spain (later to become Tecnimagen) had their own small screen B/W chassis. They did design their own low end colour chassis to use instead of the CTX chassis. I think it was called CTZ.

Sure enough, the switch in the dc socket on the back was intermittent. Thanks too Tim for mentioning that earlier.

An opertunity too compare the two sets side by side, they appear to have different crts fitted. Although the type numbers are the same (12VCUP4) they have different phosphor colours and the shape of the bowl is quite different.

Yes Daz, they are fitted with VHF/UHF tuners.
/07 is the execution for Ireland, so the fitting of a VHF/UHF tuner makes sense. The set in the second type label picture is unfortunately missing its date code sticker but if the serial numbers were strictly sequential it should be a later set than the set in the first picture which is from 1981. There may be a date code sticker on the chassis as well.

From which set is the picture of the tuner?

Regarding the picture tube, I think only Philips Taiwan made those 12VCUP4 tubes, but there may have been a design revision. If you ever happen to open up the sets, maybe you could have a look at the white stamped marks on the CRT bell.

So far, I too have only sets from Singapore, Taiwan and Lowestoft on record. However there must be a connection with Krefeld as their code numbers appear on some TX circuit boards. I'm not sure if they ever produced any, though. They may have only been involved in the design. Other possible candidates for production would be Suresnes and Monza (where many predecessors of the TX were designed and manufactured), but I'm not sure. It was relatively cheep to import sets like this from overseas.

EDIT: I found a 12TX3001/02S with TX3 chassis, dated llate 1985, which was made in Ovar, Portugal. They may have also produced TX and TX2 sets.

In post #1 DJ Fivos mentions Philips TV assembly in Greece. Do you have any more details on that? Impossible to find anything other than that Philips had a JV (85% or so) in Athens doing Audio and Video set assembly. All details or references are welcome.

By the way, in the next update of my Philips Tuner history will be a first - but probably still incomplete - overview of the Philips TV assembly fabs.

Cheers, Pieter

Thanks Maarten, I didn't know about the /07 as a designation for Ireland. Is there a list available online of all the designations?

The picture of the tuner was in the higher serial number set. As for the crts, the guns also quite different in construction.

Cheers, John Joe.

Execution numbers are somewhat of a mess, and the official documentation is mostly lacking. /05, /07, /13, /19 and maybe a few others are mentioned in video recorder service documentation sometimes. Also there's two systems and small changes and additions are made on the fly. I've been collecting them for some years now, I have to reorganize and compile a partial list one of these days.

About the different CRT's, it could be that one of them was originally based on a A34-xxxW design and the other on a Far East or US design but compatible. If you ever have the sets open, I'm interested in the codes.

The tuner being in the higher serial number set, sort of suggests that set could actually be the older one, as the tuner is dated week 38 of 1980. The low serial number set itself is dated week 16 of 1981. Of course an old stock tuner may have been used, but the difference is a bit larger than normal.
