Note: The above examples of possible combinations are to help you narrow down the choices of transformers for your favorite tube types. How
you operate the tubes (push-pull, push-pull parallel, ultra-linear, class, B+, bias, operating points, etc.) will change optimum plate to plate load
impedance. Only a few of the most popular tubes are shown. As more tubes become available we will add them to the list. A tube manual or tube
manufacturer's technical data sheets should be consulted first, before making a decision on a proper output transformer.
