A friend gave me two pairs of 2SK2087C SITs two years ago. When the Pass SIT-5 design was introduced, I was inspired to finally put them to use. However, I was deeply involved in DIY my LM3886 error correction and composite amplifiers—a project that ended up stretching for nearly a year.
Now that DIY is nearing completion, I'm turning my attention to a new idea: the SIT PX-Mini. This amplifier is inspired by the Pass SIT-5, but adapted for the lower-power 2SK2087C and a reduced supply voltage.
I've attached the schematic here and would greatly appreciate any critical feedback or suggestions for improvement. Once the circuit is refined, I'll move on to PCB design, prototyping, and testing.
