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.
I have a couple of US millitary VT-185. Tube specification book tells me that it is identical or close to 3D6, a kind of UHF tretode. I am planning to build a preamp and hope this couple of tubes can be useful. Can they be applied in audio circuit?
