Welcome to the year 1957 !!!!

Ampex 960 ( valve ) reel to reel  machine play 1957 tape Edmundo Ros & Orchestra Rhythms of the South  with 2010 active Ampex Speakers ( 10 Watt build in 6V6 push-pull amplifier )….lovely sound…. …I forgot, I too was born in 1957.  


I thought to write these notes on a topic that is mostly neglected or not always well highlighted: ground connection. Please look at the follow schema about an easy SE tube amplifier: We see a long ground wire and and a connection to metal chassis. But the question is: how is this connection made in practice? after many years of tests in audio devices I can assure you that this topic is very, very important…
