Weight of 29 inch picture tube?

    I am in the UK. I was looking for useful spare parts inside a broken 29
    inch Panasonic TV (model TX29-AD1) and I had removed all the electronics
    boards and the two speakers.

    I then picked up what was left of the TV: the tube and plastic outer

    Phew! It weighted a hell of a lot!

    Does anyone know APPROXIMATELY what an actual 29 inch CRT picture tube

    In my case it was the old-style screen ratio and ISTR the picture tube
    had a Philips sticker on it.

    Approx 100 lbs.
  3. It depends on the EHT voltage used. If this was for a relatively modern
    set,using '100Hz' scanning, then the EHT will be higher, and the glass
    used in the front has to have better radiation protection. For this the
    figure given by another poster, of about '100lbs', is probably a little
    high, but not that far off (typically the whole set, will be about 90lbs,
    and the tube about 3/4 of this, so perhaps 65lbs). 50Hz sets, are usually
    a fraction lighter, but probably still over 50lbs for the tube. Tubes
    supporting really high frequency operation (CRT's, rather than TV's), will
    push higher (for example, a 24" Hitachi monitor, tops 100lbs, and the tube
    is heavier than the 29" examples mentioned...
