Ok, after years and years of reading about other people's "barn finds" in Goodwill, Salvation Army and curbside, mine finally happened.
I pulled into GW just as they were putting a Sony STR-6800sd and a pair of AR-2a's out.
I didn't know anything about them until I brought them home and read as much as I could.
Serial number D 10185 on one I forget the other.
I fired them up and as typical, nothing discernable came out of the tweeter & mids. So I'll assume the pots are shot.
Then I was giving the grillcloth a critical look and noticed they didn't look like the others I'd seen. So I Googled some images to confirm that. I did some more reading and found out that this pair was probably upgraded to the 2ax.
They have the square badge and the "A" pin.
What I thought was interesting is the terminal setup. So I can run a external tweeter (and mid i guess) if I prefer. Id like to restore them since they are in really decent shape. But im also fascinated that I could throw a heil on top.
I can't post any pics until I get home. I also need to take the grill off and that looks to be an issue.
