My father recently passed away and I've been cleaning out a decades old storage locker of his and ran across some items that I can't seem to find a value on. He used to own a retail stereo store in the 70's and then went to work for Technics in the 80's. Could anyone give me a real world appraisal on these items as I didn't see them in the audio blue book.
A) brand new B&O MMC 3000 cartridge. B) brand new Technics EPA-100 tonearm C) brand new Technics EPA-A250 arm unit.
I appreciate any help you could provide on their value
