It is a stock unit. Pre was not really pushed, small knobs were between 12:00-02:00 hours, big one was around 2 clock. Levels were peaking between 6-3 db.
It is a very very quit click only, it is hard to hear, but once I started to hear it is bugging me.
I will start to use again the microdrive to see if that works better. I made only 2 recording with microdrive and they look spotless.
