One of my usual spots for grabbing TV's is near work unfortunately
Over the last 2 years, CRT sets dropped off at S.A. store (who palletizes them for ??? pickup) yielded some interesting BW sets that are basically working, and yes that would be monochrome. Sometimes I give them a ten-spot as a donation if they ask me what I'm doing at the pile.
Locally, quite a few retirement and continuing care communities that clean out a resident's belongings when they move on, bring them here. CRT and even flat TVs always need to go to a recycling facility. If CRT sets are put at curb, the waste haulers will leave them behind, more variety!
I picked this nice and rare Zenith up yesterday but it was wet, so I fan-dried it out before a power up. Next post will be a picture of it working.
