Hello, I just picked up a pair of 809As on ebay for a lowball price. They needed re-surrounding, but they now sound very nice as a second reference.

I'm trying to figure out when they were made. The serial numbers are 08082 (0188 is below) and 07787 (0787 is below), and the obvious answer would be Jan 88 and July 87. Is the obvious answer right?

I'd be interested to know when they were introduced and discontinued, if anyone knows.

TIA
