RE: 6SJ7 Why an electrolytic from pin 1 to pin 5?

Posted by Paul Joppa on September 27, 2011 at 18:37:42:

Most likely, pin 1 is being used as a convenient solder tab since it does not connect to active parts of the tube. Is it grounded? That would indicate it's the cathode bias resistor and bypass cap.
