Cool stuff. I picked up a broken one of these years ago, then sold it when I realized it had a dead SAD.

Side note on this, if you use an R5106 you need to change the voltage regulator to a 12v one, 15v will fry the chip.

He has some for sale, or he did a while back. I bought one to fix a 565 Chorus.
