B&W TV PYE 12U
This set was acquired recently from a guy down south and kindly collected for me by David Newman for me to collect off him at Retrotech uk
The set is a TV12 a plastic cabinet version of the 11U chassis and by the looks of it it’s the later version with separate preset contrast controls and a EF184 in place of the more common PCF80 in the V6 position
on inspection the set appears to be very reasonable condition a few bits of cabinet damage here and there but nothing that can’t be sorted
inside looks as reasonable as the outside with some damp damage I’ve various places but generally very good not like most of these chassis I’ve come across this one isn’t covered in the remains of the wax capacitors that have melted everywhere.
The CRT was tested first to see if I need to find a replacement but this tested good , the VHF aerial socket was missing but that was soon replaced , the mains dropper has been bridged but only in one section so that will do for testing purposes as a replacement was kindly given by Chris (crusty) so when everything has been repaired this will be fitted
I think the first steps now would be to replace all those horrible wax capacitors along with any electrolytics
as can be seen by the photos the VHF tuner is a bit rusty so some time will be spent cleaning that up
I’ll be posting the progress as and when I get time to spend on the set as life tends to get in the way at the moment but for now here are some photos
I have forgotten many of the sets stock faults but these were bread and butter sets in the 1960’s for me, much better 625 performance than the earlier 11U but still had that valve UHF tuner that required a few millivolts at the top end of the band for noise free reception.
Had one as my set at home for 5 or 6 years in the 1970’s, the Ekco version, before we had a CTV.

Ah! I wondered if you'd have got it!
I saw it too and wanted it but it was way too far for me. I debated having it delivered by pallet to me but decided against it due to the plastic cabinet. Didn't think it'd survive well at all.
I'm sure it'll be up and running in no time, i can't wait to see it going
Good luck
'70
One of my favourite sets! I have an 11U that's been in the family since new. There should be some extensive reports on the set in the VRAT archives. Mine has the more common PCF80 instead of the EF184. As stated above, these were bread and butter sets in the 60's and 70's. When I started in the trade in 1970, nearly every other TV coming in for service seemed to be a variant of one of these....not because they were unreliable....far from it but because there were so many about. Mine gets an airing a few times a month. After extensive restoration, it works very well. A dropper section failed on mine (heater) and I replaced it with a capacitive dropper which continues to give good service (and reduced the heat in the corner).
Here's one thread on mine. There are others.....…and the Pye 11U bounces back yet again. – Black & White Television – VRAT Forum (radios-tv.co.uk)
Well, some success with the 12u
all the wax capacitors have been replaced together with the main smoothing capacitor and various other electrolytic capacitors
the set now works well on both systems but not without some issues along the way, various resistors especially high value ones needed replacing but the main stumbling block was the loptx going into saturation
this was successfully recovered by putting 15 volts through the overwind over a few days to drive out any damp. The set ran well for a few hours this morning until disaster struck 🤦♂️ The loptx just died 🤬so this looks like another job for Mr Barker.
That must be 3 of these that have gone down recently. As the saying goes you don’t get one for ages then 3 come along together.
The photo shows the set working just before the loptx died, as you can see it was pretty good, so I think a rewind is justified.
It does look excellent.
I never had a LOPTX fail in the chassis’s service life, but after going on 60 years that’s forgivable.
Frank
Shame about the lopty, looked a damn good picture before it died!
Regards
Lloyd
If anyone can rewind it, Mike can! Worth getting it done. Mine still has the original LOPT from 1964 and I keep my fingers crossed each time I switch it on.....
@lloyd Thanks Lloyd , it was far better than the picture says so it’s definitely time for a rewind
im trying to put together the whole range of pye badged 11u series
so far I have the TV3u , TV11u, TV12, TV13u, TV15,TV20
theres Still a few to go but it’s coming together nicely
I have a bit of a soft spot for this chassis
i also have Pam , Ekco & Dynatron versions but I prefer the pye sets
These were easy sets to repair back in the day. I think there was a version that had a radio or record player in a large cabinet.
Don't think I ever changed a lopt in the hundreds that I repaired.
Well today I had a bit of good luck for a change
I managed to find in my stock of transformers a used 11u loptx it looked tidy so with nothing to loose I fitted it in the 12u and it worked fine it didn’t even get warm so I might be ok with this one fingers crossed as can be seen both systems are absolutely spot on
Was this a Pye design or in collaboration with Ekco, the chassis is different from earlier Pye or Ekco designs?
Either way it was a good one.
Frank
@nuvistor I’m sure this was a pye design even though this chassis was used in Ekco , Pam, Invicta and Dynatron sets
Posted by: @the_telemanyes there was it’s the pye trio model 28 I have one of those too
Coincidentally there is a Trio for sale on eBay at the moment but it's in the valve radio section.
