My brother told me rental price was set to get the cost of the set back in 9 months I recall. Regards David Oh that wasn't renting, it was HP. Yes, still alive that type of store in the form of Bright House. Regards David |

I'm sure Granada TV Rentals used the brand name Finlandia ... Yes, though our one was made by Tandberg, in Norway. NRK Oslo have a VHF/UHF B/G version of the very same TV on display in the corridor of their technical block.

I believe it was one of the first to be assembled in S Wales. The Welsh ones were very poor. Several years into Sony's Welsh adventure they produced a run of sets that were approx 10dB deafer than any other set. Most places it didn't matter but many a time I had to fit a masthead amp where otherwise I wouldn't have. The factory was swamped by signal from Wenvoe ;-) I recall seeing the mast visible from the car park on visits there. -- Mark Please replace invalid and invalid with gmx and net to reply. www.paras.org.uk |

Last occupiers were Sweden, which is why there are lot of signs in Swedish around Helsinki. Much easier to guess the meanings than for Finnish which is ... different. fx googles OK we're both wrong. The czars had control of Finland 1890-1917. From then on it was largely independent. Which leaves me wondering why the heck the signs were in Swedish not Russian! I've just returned from Helsinki actually. AIUI the south west of Finland has a lot of affinity with Sweden, one of the chaps I was visiting grew up in that region, he can speak Swedish, as well as he can English. (A Swedish colleague tells me !). The other Finns can't understand Swedish, any more than I can either language. -- Mark Please replace invalid and invalid with gmx and net to reply. www.paras.org.uk |

"Bill Wright" wrote in message ... Terry Casey wrote: In article , says... As they were being built specifically for export to the UK, they would have been aligned to System I in the factory, surely. No conversion necessary - though some minor component value changes may have been needed in production. Someone I worked with found a source of brand new Pye export sets for £20 each. They only had VHF tuners (and the information on the back was printed in English, French and Arabic!). We drilled holes in the side of the cabinets for the UHF tuner and realigned the sound IF to 6MHz without any problems. Strangely enough, Pye jumped the gun with their first dual standard sets and assumed we would use sytsem G. Those sets weren't so easy to realign and, if anybody bothered, they had to replace the dust iron cores in the sound IF transformers with brass ones to get them to tune high enough ... Blimey! All very interesting! Bill I converted a 405 line set: jacked up the line oscillator, reversed the demodulator diode, added a UHF tuner but I don't remember what I did about sound. I remember watching my first Monty Python on it: 1968 - I would have been 18. |

That would have been the clever bit ! 405 line sound was AM, 625 line sound is FM -- Mark Please replace invalid and invalid with gmx and net to reply. www.paras.org.uk |

I remember the set well - I painted it with aluminium paint and had the UHF tuner mounted near the back on the top - the 14" set was near enough a cube. I can't think I built a 6MHz sound IF strip. |
