Sony Trinitron KV-2080R

[siegell]

Hi I'm a newbie, but I hope you guys can help me out.

It's time for me to bid farewell to my much loved, well-used but perfectly operational Sony Trinitron KV2080R which I purchased in 1987. The remote disappeared at some point, but I still have the oringinal manual and even the receipt. I'm trying to figure out what I should list it for.

Also, my mom has a similar era 20inch XBR which is not fully functional -- I can't recall if its the picture or the sound that's not working.

I also have a a KV13TR24 which I may or not sell.

I'd love to hear your thoughts on values. I live in NYC.
