Want to mod my Diamond SpecOp to Nitrox

[Redline]

I hear they both use the same basic board. I can't find schematics anywhere.

Itīs an obscure amplifier, made by a very small Boutique maker, doubt such information exists anywhere.
Do they have approved Service Centers?
Techs there might/should have servicing information available, including schematics.

That said, I find it quite unlikely, specially after checking the Company Headquarters and "Factory" ??? : 8637 Windfern Rd, Houston, TX on Google Maps and finding it an piece of undeveloped land in the middle of nowhere (just check it yourself):

I *suspect* they have stuff made in Asia by the regular OEM makers, with their graphics and style of course, probably even own circuits.
There is NO WAY that the amps shown, plus an extensive guitar line, are made in that tiny corrugated tin shack, with a dirt road access.

I see some models are designed/built with Soldano cooperation, I know there are a couple Soldano dedicated Forums, maybe you will find some info there.
