Need upgrade info for my Atma-Sphere Novacron Amps

cabsvrt · 23rd October 2010, 08:55 AM

Many moons ago I had the schematics and instructions to mod and upgrade my Novacrons. I have since moved, and have found all the parts I ordered, but not the instructions. Does anyone have these instructions available as they are not online anymore. I remember one part was to put resistors from the output tubes (Cathode) ?... HELP!

I have never seen or been inside a Novacron. I've upgraded MA2s and have a set of the original MA1s that I am upgrading now. All of these amps started with 9pin input and driver tubes, so going from those to the octals I know about. Not having seen the Novacrons I don't know where to start unless I see the original schematic. These amps are ridiculously simple so drawing a schematic is easy if you know what you are doing. I don't know what else to tell you.
