Now when Schade and Reich did their work, there were no standard transformers nor companies selling a product line of tube transformers. It was simply assumed that whatever transformer was required would be wound for the voltage needed. Today we need to approach this aspect of power supply design a little differently. Since the vacuum tube is a high-voltage, low-current device, and most speakers are low-voltage, high-current devices, the mismatch between them would result in very audio low power output if they were directly connected. Matching transformers not required for low-impedance loads. A transformer is essential at the output of the amplifier circuit for matching the impedances of vacuum tube and speaker.
