Hopefully some of you former Altec employees/associates can determine if this is fact or fodder.

Vintage Altec Lansing 1569-A Power Amplifier - eBay (item 230364178887 end time Aug-11-09 15:49:05 PDT)

I had this amp built in the Anaheim, California plant in 1978.
Something about having both a 1568 and a 1569 built in Anaheim in 1978 strikes me as questionable.

Is this possible, or mushroom food?
