I want to play around with some different tubes. I got myself 6550,EL34 und 6l6 and a bias adapter from tubetown.
The VH4s is built in 98 and has the blue front.
So right now there are EH EL34 in and I wonder that I measure 60mV(=60mA) and I expectet the half because the bias adapter is plugged into one tube. Also I can just find one black trim pot near the Input and if i screw nothing changes.
Just for Information I switched to the 6l6 position and measured 35mA.
Can please anybody help me
