Despite the rather senseless carping (c'mon boys, cut the crap!), this is
cool! Thanks for posting it!


I agree. An interesting post. And now for my usual dumb questions :-)

1. Have you built one (or more) and if so, could we see a photo?

2. What do you mean by "star grounding technique?"

Star grounding is a VHF/UHF grounding technique. VHF and higher have to
have VERY short lead dress, including grounding. Star grounding is basically
taking the grounds from each pin that requires a ground or a bypass to the
closest point possible on the chassis. This makes the socket and
grounds/bypasses resemble a star.


At the audio manufacturer where I worked, star grounding meant to take
all grounds to a single point on the chassis, thus having ground wires
radiate like the points on a star. This avoided ground currents
flowing through the chassis.
