Sinclair Microvision TV's. Handheld in B&W

I've owned a Sinclair FTV1 for some while but have added a MTV1B of late so thought I'd make a short video about them in 4K. I was always fascinated by the Flat CRT design in the Sinclair set. Despite being interested in amateur TV I don't collect TVs because of the size but I do have a few small TV's as shown here. Of course with no analogue they are not much use as intended, but usable with a modulator. Warning TV's contain high voltages and are dangerous to work with.
