If you have a 12ax7 small tube besides the 6ca7's(EL34), you are in the 76-78 area. They changed to the solid state driver(no 12ax7) sometime around 78 I think. I've had both but prefer the tube driver but you need to bias them a little cold, around 14-15mA to keep them from melting down. I had one that MM couldn't get to stop burning up tubes until then converted it to SS driver. The one I have now, a 2-10 65 works fine and is being used every weekend with my band with no problems.
