ok here is how...you GENTLY wiggle it back and forth (DO NOT TWIST)...it will come off. Some are attached with something, so look underneath the board 1st and clip away any zip ties or other things. Again do it gently, but with a bit of force and it will come off. then unscrew the 2 retaining metal rings, pull or cut off the 4 or so plastic things on the yoke. Gently but forcefully twist the whole yoke from the bottom and it will come loose...work it up and off the tube and off you go.
Once you do a few it gets easier. Screw casing back on and find a dropoff for the tube (Goodwill (some), Best Buy (2-3 a day typical limit) or you might have a drop off in your city for free (not many do this, but some have it)
I will say, that is not alot of money in general for the weight and size of those to go out of your way (IMO) to get them. Computers...much more in terms of $$ for space and time...again IMO. I only do tube tv's if I HAVE to in order to get other stuff and even then I limit it to 36" or less...really 27" or less LOL
