Tape record stereo phase problem (AKAI GX 4000D)

[highvoltage]

Hi, im new to using tapes, but i have aquired an AKAI GX 4000D, which i absolutely love to record stuff onto from the box.

I have noticed tho, that the high end of the spectrum gets phase cancelled of a stereo recording in a cyclic manner. If i listen to L/R channels independently you can only hear a slight fluctuation, which should be normal i guess, but they are not in sync, so it gets this phasing sound (at around 9-15Khz) if mixed to mono.

I know its a consumer machine, but i dont think stereo phasing should be an issue. Any ideas?

Thanks !

(I can record a mono pink noise in stereo and show the phase flipped sound if it helps.)

Get a tech to cal it. The Azimuth is out. You can end up with phase issues with incorrectly adjusted Azimuth.

I like that it is such a wizard-ly word. Azimuth.
