WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Looking for a good tube, cheap, high transconductance, for a top grounded grid tube in a cascode preamp with a high heater to cathode voltage. Also thinking about the 6GK5 and the 6ER5, & 6DL4. Just trying to find people with experience. Thanks, Ray
I just used a 6GK5 as a linestage buffer... worked great. 6an4 looks even better on paper. I have som around that I bought for the very putpose of cascoding, but never got around to it.
