I sure hope so, given the lack of output coupling! Moreover, I wasn't aware that these "space charge" tubes had a particularly low plate impedance, given that they run at such a low voltage and puny currents. So, I am at a loss as to how a 150 ohm to 600 ohm device could just be "connected" without having a huge impedance mismatch - unless the output is being taken off the cathode. Even then, a cathode follower's output impedance is the inverse of its transconductance - which these little tubes cant have much of!
This thing has been listed for months, by the way - I just ran across it again recently and thought I'd share a laugh. So, there's a listing fee being paid over and over again for some reason or other....
