Clip showing a HMV 900 pre-war television in operation. Television is from circa 1937 (first went on sale in 1936). Camera goes a bit wonky when zooming in because I stood on the Aurora standards converter!

  • I've often wondered with these pre war TVs that used a mirrow to view the picture...does this mean that any writing appearing on the screen apprears backwards? Or does it appear backwards on the tube and so when vioewed by the mirror appears the right way? Great demonstration BTW.

  • @SwingBandHeaven

    As you guess, the image on the CRT is upside-down, and back-to-front, so that when it is reflected in the 45 degree mirror it appears correct. BTW. the reason the mirror is used is because the CRT is very long (they had a 40 degree deflection angle). If viewed directly the television would need to be very deep. Instead. it is mounted vertically, the base of the tube on the floor of the cabinet.
