RE: air tight /acoustic masterpiece 101

This is an EL34 diagram, the only difference is that the Pin 1 is internally connected to Pin 8 in a KT88.

So what you do is take Pin 4 (G2) and unhook the ultralinear connection from the output transformer. Take that lead and put some heatshrink over the end so it does not contact anything.

Then take a 100 ohm 1 watt resistor and solder it between Pin 3 (plate) and Pin 4 (G2). Check the bias to make sure everything is cool/correct and you are good to go. Most cases the bias will not be adversely affected.

Then enjoy psudo-triode ( I like that connection better if you don't need the power)
