Accuphase P-7500 Power Amplifier

The P-7500 is a super-class "stereo power amplifier" born from a full model change of the P-7300 after six years of development, combining the technology cultivated in the development of the A-250 and A-75 with a powerful output stage with class AB operation.

The power amplification stage uses 10 parallel push-pull class AB operation with power transistors, achieving high power output of 300W/8Ω, 600W/4Ω, and 900/2Ω.
