Lloyd,

I fitted flyback blanking as per the Bush TV53/56 etc. schematic. I have also done it on the TV32 I am restoring/repairing.

At least it worked I suppose, although it doesn’t work now, just a blank raster with faint hiss on the sound.
There was one like that at my local auction house a while back. There was also another 'globe' one next to it that had had the same 'modification', so someone had been busy! I didn't bother to stay around to see it sold, but looking up the results later I seem to remember that it didn't make an awful lot - perhaps I should have bought it for the cabinet...that's the remote control for the new innards in the package taped to the top of the cabinet. It was quite nicely done - you can see the bit of an old radio cabinet that's been let into the back where the hole for the band three converter would have been. I took a couple of photos of it at the time - shown below:-

The science museum in London also like to do the same thing. I took these pictures below when I was last there.

Oh dear! They could have at least kept the shape of the original screen mask! At least the first one still has a CRT. I wonder if the science museum kept the original guts?

I had some fun getting the ‘Thorny-Bush’ chassis running the other day, it had a blank raster and only faint hiss for the sound, no idea what it was causing it, because once on the bench ready for testing it decided to work!

Regards
Lloyd

I was thinking exactly the same thing...and also regarding what happened to the original guts of the local auction house one.

The science museum did have an original 'unmolested' example among some other similar radios - shown below. I seem to remember that there was another similarly 'modified' old telly there, but I don't seem to have a picture of it.
