The grounding scheme is unusual.
No star ground. A mesh ground plane that connects to all ground traces.
The high current traces, the small current traces and the ground plane are all connected.

Boards have arrived for the Simpelstark amplifier. I haven't had a chance to assemble and test one yet though.

My camera is smashed. They look the same as the version Valery built but with the corrected op amp connections.

BTW, went ahead and bought the Rigol scope you suggested. Received it two days ago but have yet to fire it up. Looks like a really nice scope!


Thanks

Nice! They're a great little scope for the money. More than enough functions for audio as well.

Great move!
A scope is a must-have instrument as far as you deal with sophisticated electronics.
Otherwise - "It's difficult to find a black cat in a dark room. Especially if it's not there"
