Standel expert needed

[jvm]

Anyone know of an authority on Standel amps. I have one that has been seriously cobbled by a previous "repair". I suspect there are a lot of added parts. I have no idea what this circuit is supposed to look like. Have searched for schematic/photos with no luck. Any help appreciated.

What model is it?

Sorry. Forgot to include model. It is a 70J15.
