My parents had one of these , they bought in the early 1970's, it never went wrong & was still going strong in 1995 when my sister had it after Mam passed away.
I was fascinated on how it soft of converted PAL to NTSC to get round PAL patents. Remember reading somewhere that dropping a line of chroma & repeating the last one with a delay line should not have worked very well in theory, but in practice it worked brilliantly. I remember the sharp, vivid pictures it showed. The only thing Mam didn't like was the rotary tuner: she'd often tune it into a channel up in the 40's/50's/60's where Sutton Coldfield & Waltham lived & get a fuzzy picture (the aerial was a group A verticaly polorised) instead of the 20's where Nottingham TX lived, I put sticker's on the dial for the channels but she'd still get it wrong sometimes...
