I have a bunch of red, blue, green, yellow and white or clear. The red ones i have are bullet shaped with one lead shorter than the other and the base having a flat side associated with the shorter lead. right now with my resistor of 380 ohms, i am getting about 3.8vdc on the cathode with a plate voltage of 360 and a plate resistor of 100k. Plus there is a plate to plate feedback resistor of 100k(from plate of power tube to plate of 6j5).
So, for the 6j5 i would use it on the tube's cathode. with cathode of the LED grounded? I would find it informative to see if using a LED is of significant difference to the sound. How many LEDs do i need per tube? regards, Dak
