    Heathkit AA-71 data?

    I have a pair of Heathkit AA-71's in the shop for a general check-up/tube testing. It would be nice to know the bias/balance settings and measuring points. Does anyone have any data (build sheet) on this guy?

    ADS L470/2

    I picked up a pair of these recently for $70. From what I have read these were made in ~1985 so I’m inclined to recap the xovers. Does anyone have a schematic for these? ADS is not listed in the AK database. I assume I’ll need to pull the woofers to access them. I found a hand drawn schematic...
