Ok, up first we have serial number 83/06506, which I purchased 19/4/2003 from a shop called ‘Luna’ in Nottingham after seeing it advertised on eBay. It’s a MkI with EF91’s in the RF chassis, CRT is an MW22-18 straight gun with a nice big ion burn in the centre! Has T shaped laminations in the lopty. This was my very first vintage valve TV, and over the years I’ve done little bits to it to get it in working order, and it’s still working well now. Can’t find a photo with the date on the capacitors…

Next set, a TV12B, serial number 66/01297, with a Sutton Coldfield RF chassis. Got this one from a chap in Rugby back in April 2006 via eBay. Not in bad condition, I have done a bit of work on it, new caps and some new wiring, the RF chassis is missing it’s bottom, and the CRT is an MW22-16 with ion trap, not quite the right tube, but it works! It did have a Mullard Radiant screen MW22-16, but I have swapped it for one in my Philips 385U on a trial basis. Has May 49 stamped on one of the electrolytics.

Next set, another TV22, serial 83/39393, another MKI, came with an RF chassis that had a band 3 tuner attached. This one came from the NVCF in 2010, not sure why I thought I needed another TV22, but hey ho! It had something about the tube being knackered written on it, H-K short if I remember, but it turned out to be a partial heater short instead, and the heater popped eventually. It has the later focus assembly to accommodate the MW22-16 CRT and its ion trap, also the width control comes through a slot above the serial number, and the components for the video drive to the CRT are mounted above chassis. This set uses the I shaped laminations on the Lopty, and the ceramic former for the EHT rectifier heater winding. I had this set up and running beautifully, excellent picture, I even had it on display at ‘the festival of vintage’ at York racecourse back in 2011, where it ran flawlessly for 8 hours solid! But sadly in 2015 the lopty gave out, primary-secondary short.. I really must get it rewound!

Lastly, another MKI TV22, serial 83/10611, some of you will know this set from my recent thread! A last minute purchase at this years RetroTech, just a chassis, no cabinet! Well, not yet anyway! Almost fully restored, MW22-16 ion trap tube, but the focus assembly is the earlier type. T shaped laminations on the Lopty. RF chassis is the EF91 type, but isn’t going to be used due to a broken tuning control. Currently working very well, against all the odds!

1st photo is in my old workshop, where the 1st TV22, a TV62 and the TV12B had pride of place.
2nd photo is of TV22 no.2, just days before it died, I had set it up in our second shed, picture was great.
3rd photo, is the 3rd TV22, minus cabinet! I do have one for it, but it’s going to need a bit of work

Regards
