I just wish I could find a schematic diagram for it. Any of you owners have one or know where I can get one? I'm willing to pay something.

Fiddler, Lazarus's owner/designer is named Greg something. As a dealer in the '80s I did business with him. Muse, huh?

Uuh...what would the tech DO? Without a H-1A schematic diagram and an H-1 amp, he/she wouldn't know what the differences (= upgrades) are.

It's full of capacitors and resistors, large and small, that can be upgraded. I've started upgrading caps on mine, replacing the lo-voltage PS bypasses on the bottom of the board. But I still want a schematic diagram of the circuitry before I do much more.
