Collins values

[MickeyMouse]

I have aquired several pieces of Collins gear beyond my needs and want to determine fair value for same. Any help in this regard would be welcome.

75S-1
32S-1
516F-2

I want to sell the S-line as a group. Original manuals included and I would rate them as an 8+ or 9; VERY GOOD is a bit of an understatement. Work great.




75A-2
32V-3

Also want to selll these two together. Also with original manuals. Cosmetic condition is VERY GOOD but I have never turned them on. 7 or 8?

Thank you!
