Optimal grounding?

Skorpio · 13th November 2007, 10:43 AM

I am in the process in building a solid-state preamp, with regulated PSU and a diamond buffer. Only linear stage:

Input->selector->volume pot->buffer stage->output

How do I make an optimal grounding?

My plans are:

All GND on input/output sockets are isolated from housing. They are connected directly with wire and connected to PSU midpoint (caps after regulation). Here are also both terminals from volume attached and GND from buffers.

Housing is atteached to midpoint of first filter CAPS via 10ohm

Any problems?
