We used to have one when I was a boy, the legs were wonky. It was only used once a week, for Family Favourites on a Sunday lunchtime on the BBC Light Programme on 1500 metres
Pretty sure this is the unit we had when I was a kid. Sounds really nice….probably Germanium output transistors in the power amp. That sounds better than a lot of modern rubbish.
I don't mean to be rude, but from what's in this video I wouldn't call that 'fully restored and repaired'. At the very least, for reliability the deck will need the cam, speed change mech, and platter centre bush cleaning and regreasing, the trip pawl cleaning, and the idler resurfacing ( a once-over with an emery board may be all that's needed to restore optimum grip). You will also now need to reset the antiskate which is the black plastic screw you were adjusting at the rear of that c137 deck. The set-down position screw is in fact on the right hand side of the arm bracket, if you lift up the arm you'll see it. I would also lift out the panel to check and clean the pots and controls on the amp (though this transistorised kit is surprisingly robust, and needs little work if the output stage is good). A 3A fuse should be used in the plug. Liked your solution for the broken switch - saved the deck from being scrapped.
By the 70s the radiogram was on its way out consequently the cabinets became rather cheap and tack to look at being made out of particle board covered in plastic fake wood [Fablon]
