Inherited amp


I have inherited two tube amps but there is no schematic diagram. It came with two sets of seven matched 6550 tubes (yes, seven). This is my first posting on the forum and I am not sure how to attach a picture.Any suggestions?

Don’t think this was a kit. Kinda looks like a home project.  Very good workmanship!  Hope you find the builder.

Since the transformers are made by Hammond, maybe these are amps from a Hammond organ?

Time for Ralph to chime in.  Agree that it sure looks like someone knew what they were doing and did it well.
