Little green Pye V 220 - UK Vintage Radio Repair and Restoration Discussion Forum

ekcopyephilips · 13th May 2018, 6:20 pm

Hi everyone

I picked up this little Pye on Saturday from a lady 3 miles down the road from me that clearing out her home after her husband passed away. Purchased in the early 60's it was used until the mid 70's when they invested in colour. The little Pye was then put in the attic where it's been ever since.

Now as everyone knows there was a Pye to factory in Lowestoft so this was possibly made there, this was picked up in a place called Harleston which is only 15 miles from Lowestoft, so it hasn't travelled far. Interestingly Pye had a small factory in Harleston that apparently assembled complete sets so this could even been assembled there.

It's got a great coating of dust inside and it doesn't look like a soldering iron has ever been near it.

Any tips for this chassis apart from the usual things? I've got most of the red tv servicing books, does anyone know what year this one will be in as all mine are currently in the loft.

I love the colour and the light modern looking plastic cabinet. At the time it must have looked extremely modern compared to heavy dark wooden cabinet sets.

Cheers

Mike

Does anyone know how to decrypt Pye serial numbers ?

Blimey, I used to repair them back in the day, incremental tuner with coil expanding mechanism if you weren't careful...

Looks to have the same chassis as my Pye V210, should be pretty straightforward to restore, most of the caps are on the PCB. I had tuner problems with mine, the contacts had green corrosion on them, but cleaned up OK.
Be VERY careful when cleaning the tuner, there are lots of small & fragile coils that could be easily damaged.

There are also a couple of caps round the LOPT to deal with that are hard to access. I can't remember if I removed it, or managed to just move it enough to replace the caps.
It took a couple of hours for the CRT to come up, but picture is fine now.

Cor, the memories. We had one come in our workshop in a terrible state. The customer had moved it to paint the skirting board behind it, and had put it down a little too close to the gas fire. It looked like something from a horror film! All that plastic....

Am I right or wrong in thinking that these used to be referred to as ‘Pye Pioneers’?

Hi Mark

I see yours has a metal rectifier, but mine appears to have something slightly different, any idea what mine has?

Cheers

I seem to remember that later production sets were fitted with silicon HT rectifiers, possibly two OA210s in series.

The PYE 'Pioneer' was the model TV1 fitted with the Dual Standard V700DU chassis complete with UHF tuner. 17" short neck AW43-89 tube.

Cabinet was almost identical with horrible back securing clips that broke off the cabinet and refused to glue back with the glues we had back then.

Ahh, thanks for clarifying that, John. It was the plastic cabinet that made me wonder!

You beat me to it! They were a right b

gger to replace!

Hi all

I found my red 1961 tv servicing book that covers this model last night. It looks like the set i have uses a rectifier made by Siemens.

Would this also be a selenium rectifier or silicon? If selenium, i am presuming that i really need to disconnect it and use a silicon diode and resistor in series after all these years. Apart from the terrible smell when they fail i have read that the fumes are toxic.

Cheers

Mike

Most of these 1960/61 Pye TVs employed an Automat make metal rectifier.
Apart from the higher forward voltage drop compared with silicon diodes the Automat rectifier was very reliable. I replaced the metal rectifier in my Pye V600A not because it was faulty but as an attempt to improve the performance of the line output stage. Even after that action there is only just sufficient width.
The 23" V600A is fitted with a similar chassis as in the V210/V220.

The Automat rectifier was then fitted in the Masteradio T852.

Refer to post No.4. The green Automat HT rectifier can be seen in Mark's Pye TV.

Yes they are; but if one does go pop, you're unlikely to stay around long enough to breath enough in to do you any lasting damage!
