Sunn Beta Lead (looking for schematics)
« on: February 14, 2013, 11:28:13 am »
As subject says, I'm looking for schematics of Beta Lead. I found only one but it's too fuzzy to read some values, so anyone please share if having something clearer.

Edit: These links work as of July 2014. Although jpegs, the resolution is OK and they are in color which helps alot on the pcb layouts.
