Small signal parafeed transformer

[vetmed]

What if any would be the virtue of taking the ground  return lead to the top of cathode resistor? I'm looking at something I built more than 20 years ago and wondering why I did it : It works but then I was just following a schematic with little real understanding of what I was doing Hopefully I have made myself understood and appreciate any input.

Have a look at the "Valve" archives there were a few articles on parafeed theory, if I recall correctly there was one on the four ways to connect and the pluses and minuses of each...John

It gets the signal current out of the cathode bypass capacitor.

Thanks, I found one article in valve magazine entitled 12 Ways to parafeed.  It showed the 12 ways but offered little explanation, so your response save a lot of searching
