Transistor PA by sanken. Sanken 2SC2922 - 2SA1216 - Output 200 Watt - Maximum voltage of 180V - Maximum current of 17 amperes 2. Sanken 2SC3858 - 2SA1494 - Output 200 Watt - Maximum voltage of 200V - Maximum current of 17 amperes 3. Sanken 2SC3264 - 2SA1295 - Output 200 Watt - Maximum voltage of 230V - Maximum current of 17 A Of the three types of sanken, the whole power equals 200Watt. So don't speculate which is the most wattage among the three. The difference only the max V.
Even though the three series transistors the price is different, especially Sanken 2SC3264 - 2SA1295 which is more expensive than the others. Vaenga zhelayu peredelka prikoljnaya.

It is perfectly ok to have “non 5Vs” coming out of a 5V regulator. All your voltages should be referenced to a common point. Having it as you show it, even if you are copping others, IS confusing.
The regulator is just a component, not the final design. By the argument you put forward, any variable power supply that uses, for example, a LM317 regulator would have a 1.25V output all the time as it is a 1.25V voltage regulator. The LM317 is just a part of a circuit that happens to be a 1.25V regulator, but produces a variable output.
The same way the regulators in this circuit are being used to produce “non 5V” power rails. They are just used to get a power rail that is offset by 5V from another rail. But all rails are measured W.R.T. I wouldn’t go lower than 20-24V for the power supply,but at least 30V is recommended. For low power amplifier, I think a different design would be better. If you are using a transformer (I recommend toroidal because of their size), and not a SMPS, you will need a bridge rectifier and some beefy filtering caps (I personally used 2x10 000uF per branch - positive/negative).
About the potentiometer, although you could add one before the ” Input -P1” of value 100K, I suggest building a pre-amp circuit that also has tone control. It is +12V referenced to -30V. Imagine that we use a multimeter and we put the black probe (ground) to the -30V rail.
If we measure the real ground (which is 0V), on the multimeter digit we would read +30V. If me measure “+12V”, on the multimeter it reads +12V. BUT, if we put the black probe on the 0V ground, on the multimeter we would have -18V. We measure the electric potential difference, V2-V1. When we measure “+12V” rail, we consider “-30V” supply to be V1. I used this notation because we connect the COM and VSS port of the IR2110 to the “-30V” rail. If you want to build an amplifier with such a low output this schematic will not do it and it is a bit overkill I think.
