Based on bedini's classic power amplifier 25/25, loyal to the original minimalist style, and using high-quality modern transistors, it has better parameter consistency and lower bottom noise.

MPS8099/8055 has been replaced by 2SC2240/A970,ultralow noise 2N3440/5416 was replaced by KSE3400/350 ，Ultra-low output capacitance improves slew rate stability and power amplifier bandwidth。 2N 3055G was replaced by NJW0281G /2SC5200，Tell me in advance which transistor you need, and if you don't need to weld the power transistor (NJW0281G /2SC5200), tell me in advance.
