This is my first test of the incredible Pioneer RT-909.
I made a whole revamp (mechanical & electronics).
And really it sounds wonderful.
Tape hiss sound heard in the video it's from iphone's microphone self noise, not from tape.
Actually tape hiss with ATR Master tape & new calibration setup (250nw/m) it is extremly quiet.
