I think that transparent Drive that you pictured will be a wonderful addition to your offerings here. I know I can’t wait to carry a kit for this in my shop.
I know everybody, including Jimmy, will say gimme some of that T—- once you make it available. I believe the version 4 of that circuit uses an LM1458, but the one you have pictured is accurate in earlier models. I have some of each ready to go into kits.
