    I would consider it worth nothing and just bin it - fully working CRT monitors are worthless these days.

    If you have about 1000 lbs of old circuit boars, someone will buy it for about $10.00 to recylcle all the metal and plastic out of it. Of course it will cost about $2000.00 to ship it to the facility...one of the major problems with recycling. Thats why in Canada, the Government is charging a heafty "recycling" fee on any large electronic product...such as a flat screen....non-optional ...of course!!!

    Follow mneary's suggestion - look up E-waste in your locale and dispose of these items properly and safely. Electronics contain recyclable metals ( copper, aluminum, steel, gold, lead & tin). In my area, there are machines that separate electronics into their metal components, and shred the non-metal pieces. Recyclers pick up large quantities, and welcome personal drop-offs. A government-sponsored commercial asks, "If you're still sitting on your old electronics, what are you waiting for?" It shows an easy chair made from CPUs and laptops.

    This comments make me dream about a large tripple-channel oscilloscope, where each channel has it's own color on the screen.
    But, as you said, the tube was never designet for that kind of use.
    Maybe if the coils where rewoundet to decrease inductance.

    u can use tv tube u can just make cct that plugs into it like normal rf or av or make a cct that uses tube derectly and is tuned with it but yes it wont be as good as a normal scope or it will be delayed sos not in time with wat ur measuring im planin on makin a a hardcore scope from a masive crt be using alsorts of gear in it pic valve transistor
    i should consider using lots rear veiw projection tv tubes
