The PSU Tank Amplifier is indeed great

A tank power supply is almost the same as a Class H power supply, with the only difference being the voltage and usage. In my opinion, a tank PSU is more suitable for power amplifiers used for subwoofers. The installation itself shows that this PSU has a tank capacitor, so as the name suggests, the tank is used when the main capacitor runs out. The advantage of a tank PSU is that it can supply high voltages up to twice the voltage listed on the capacitor. Hope this is helpful.
