This MC boost transformer is ideal for SPUs using the No. 6600 JS transformer. The sharp high frequencies and the tenacious sound in the mid and low frequencies make the SPU sound even more energetic. There are dull stains. There is no problem with operation, but there is a slight wobble in the RCA terminal (Tamura Eiji)
