    Try contacting forum member VR3. Those split board crossovers are a PITA, I won't touch them.

    If they're anything like the split boards on a 1B, they're a piece of cake. Buy the Mills resistors, the ERSE resistors are physically larger and harder to place on the circuit board.

    This one would work but would probably look different. Most SDA1's came with passives that had the foam on the fronts. If i remember right. the one pictured in ebay will have a plasticy front which would work but would look out of place unless you get a pair. I believe the ebay passive is SW121 which came later on the SDA1C

    The eBay PR is a SW120, it's written clearly on the back.
