Hi appreciate the posting - just ran across it. I am looking for H1-A schematic and documentation as well you can see my 'wanted' on USAudioMArt. Have collected quite a bit, but no true schematic as yet. Any luck on your end?
Maybe we each have some useful info that would be good to swap? Let me know.....

A fellow shark provided me with a schematic that they deciphered from their amp. (Thank You)
I also have a partial schematic from a vintage audio magazine when they reviewed the amps.
The schematics are for a friend. He has 4 of these amps and so far, they are all different.
It seems that the amps went through a continuous revision process. (maybe based on parts on hand)
There is a person that acquired the parts and schematics from the now defunct Lazarus.
I (we) have tried numerous times to contact him for parts etc but he is not very responsive. (putting it politely).
I will PM you so we can exchange the info we have.
