Tube basing Question

Posted by Jimmy on January 26, 2004 at 13:22:21:
I have an old guitar amp I wish to repair for a friend. It is a Hilgen Pace setter R2521D without tubes or any tube number identification. It looks like 7591 for finals. Preamp looks like a basing of either 9CZ or 9J plus has one 7199 in the second position on the PC board. Anyone have a schematic or list of tubes based for 9CZ & 9J.
