National Model 90 schematic?

Post by hossymandias »

Hello all,

I am attempting a recap of my old National Model 90, and I can't find a schematic anywhere. Is anyone familiar with this amp, or does anyone know where to find documentation?

This is not the same as the National Glenwood 90...at least on the outside. this is a tube head that I bought with a 212 cabinet. The cabinet has since been cannibalized, but I'd like to get the head humming again (preferably with no hum) :roll:

Thanks for any advice or tips!
