hi
i've got these 2 API cards that i have been told are phono preamp cards. they have a 2520 opamp, 2551 opamp, a couple of 4558 ICs, a 2623 output tranny and the usual peppering of caps and resistors. there is no card number etched in the usual place as per the 312 and 325. there is a much smaller number etched in the component side: "ASSY 1009-107" oh ya, these are double sided cards.
i can't turn up any documentaion regarding these cards. anyone see these before? or could verify if they are phono preamp cards or not? a schematic would be great...i can try to borrow a digital camera if there are any API guys who would like to take a look.
thanks
