My preamp also uses those 0A2 and I have a bunch of "made in USA" ones that look right the same than those "National", using the same orange color for the brand letters, but they're supposed to be RCA. They all failed in a quite short time in deliver de stabilized voltage they should. I guess they might be chinese.
Do you know where to get reliable 0A2? They also last little here.Rerurn to Romy the Cat's Site
