Insides of Lazarus H-1A amp...

Yep, thanks for refreshing my memory, Greg Miller. (Andy was close, hehe!) I went to his house in Van Nuys when I bought the amp. He seemed burned-out on the business, but that was because his business was floundering. I think he built really good equipment, he just had a hard time with capital.

I wonder if a good tech can take the H-1 to H-1A level? risky without schematics?

ALSO: has anyone tried the H-1, H-1A in mono?? most people I talk to seem to prefer stereo.

"I wonder if a good tech can take the H-1 to H-1A level? risky without schematics?"

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.

Jsujo, yes.. risky to upgrade to the H-1A without schematics. But a good tech can always change the factory pc to something exotic and have the circuit board resoldered with lead-free, 4% silver solder. These tweaks will help. But if you're set on an H-1A, I have a lonely unit not in use.

I have two of the "Class A" models in mono right now, using the XLRs... sounds pretty darn good. :-)

If anyone is interested, I have lots of Lazarus literature & reviews. Jsujo, one review compares the H-1A stereo amp versus H-1A monoblocks. The monoblocks had more separation between instruments and better high frequency extension.
