Now I really like my early MSD 7A- it isn't a 7AL and it doesn't have the bid plastic cover on the side of it. So when I saw this unit here on ebay, I had to have it. The bonus was that nobody else felt the same way and I didn't have to "overpay" for it.
I beleive this was the 1st generation desing of the MSD unit. I know they were around in 1976 and the company started manufactuing systems ~ 1970 so does anyone know when this design first hit the scene?
Note the large heatsink base that the cover bolts to.
