I should add that most of my TV viewing in the 70s was from the back of the set via a mirror on the wall at the back of the workbench
Many of that was either viewing the test card and thinking what a pretty girl Carol Hershee was or at a crosshatch pattern when adjusting the convergence on those new-fangled colour sets...
Some test card music was good too although more usually Radio 1 on 247m belting out from a scruffy old workshop radio...
Very happy days
