Finally got a chance last night to take some photos of this Pye 201T, which I got a few months ago along with a donor for parts. This is now one of the oldest sets in my collection and other considerable find for 2012.
What you are looking at is an early example of Pye televisions that were being made here in New Zealand at the time, all were 625 line.
The 201T started off in December of 1959 with an initial run of 300 according to my knowledge, but not sure how many more were manufactured and how many years this model ran for.
Both sets are not in the best of condition, cabinets/chassis have suffered due to sitting outside or in a very damp shed/garage. One set is slightly better than the other and thats what is shown here.
They came from Auckland from another vintage radio/electronics enthusiast who could not bear to throw these out, thinking that someone might want them. Thank goodness he didn't.
Like an English Pye TV's this chassis is live with series filament chain running P series valves. The CRT is a Philips AW 53-80, not the sort of tube I'm used to seeing . The chassis mounts on the side of cabinet and the whole thing slides out, making access and servicing very easy. The chassis position and layout reminds of an American design in some ways.
The circuit and chassis layout is very closely related to an Australian Pye chassis T12-D. Comparing the two they look almost identical.
In regards to the valve lineup, it uses mostly PCF80's through out the set.
PCF80 - Oscillator/Mixer
PCC84 - RF Amp
PCF80 - 1st I.F./Sync Clipper
PCF80 - 2nd I.F./Sync Separator
PCF80 - 3rd I.F./AGC Key
PCF80 - Video Amp/Video C.F.
PCF80 - Sound Limiter/Sound I.F.
PCL82 - Sound Output/Audio Amp
PCF80 - Horizontal Oscillator
PCL82 - Vertical Output/Oscillator
PL36 - Line Output
PY81 - Boost Diode
DY87 - EHT
PY82 - HT Rectifiers
So I class the 201T as being rather rare and the 'better' one is going to be a project and a half!
When I do get to this, I'll focus on getting the chassis up and running first and worry about the cabinet later.
There is a lot of wax caps and resistors under there which will all be past their 'use by date' so I've got some work ahead of me with this beast. At least I have spare parts should there be a faulty LOPT or the likes. Hopefully one/both of the picture tubes are still OK. I should test them first.
I doubt whether there are many more of this model that still exists most of them would be buried long ago so I've only got these to work with.
So when I get to this one there will no doubt be an update here of course!
Some photos and a circuit below for your amusement.
