FYI the Impedance of the HR20 (the one I have) secondary of the audio transformer is 5 ohms. The 38-7XX speaker is supposed to be a H31 with that secondary of the audio transformer being 1.25 ohms. So essentially what I want to do is to see if I can find an audio transformer with a primary impedance of 7.5K ohms and a secondary of 5 ohms that can handle the power output of the 6F6.
