Oh man!! $20 bucks for the 707s!! I’ve not gotten a deal like that in years. My area use to have deals all the time on CL but it’s dry now and everyone wants top dollar. Ive found some good deals over the years tho, a SX-1250 for $40, that Kenwood KD-550 for $40, needed some love but that was no issue for me. Recently helped a buddy out with some HPM-100s and he gave me an Optonica SM-4305, so I guess it’s not been so long, but yea I’ve not gotten a deal like that in years. Those missions are super collectable, I know of one set out in Sac at an actual vintage HiFi shop and he’s asking $4-500, I’ve always wanted a set, that white just looks so classic audiophile, they sound great too!
Well good luck on the L-86s hope you get them, they are starting to be harder to find. The price on vintage JBL has been going up over the past few years. The asking price is something id jump on.
