Hi,

I had troubles trying to do the alignment on a MTR90 II.

I started with the playback alignment playing the 1khz signal on the
MRL tape and tweaking the repro gain pot 'till the meters read 0 Vu
(The reference fluxivity of my MRL is 355 nW and I was going for a +6
alignment). No problems here!

The problem started with Bias calibration: I loaded a blank tape and
recorded a
10 khz signal (from the console oscillator), with the remote set to
REPRO and started turning the bias pot just to discover that the
needle on the meter goes all the way to right (past +3) before
reaching the point of going back. Is it normal behaviour?

Then I went to do REC gain! Again recording a 1khz tone with the
remote set to REPRO, all tracks armed, and the needle (on all 24
meters) don't go past -20, no matter how much I turn the REC gain pot.
The tone was recorded and reproduced, but obviously very low. Looking
at the meters on the console set to read BUSS OUT I could see the tone
at 0 Vu. Switching the console meters to read the signal coming back
from the recorder showed a very weak signal. The funny thing is that
when I change de console oscillator to 10khz, the OTARI needles go
midway and then its easy to get to 0 Vu with a little tweak in the REC
gain pot.

As you probably noticed I'm not an expert in alignment!
I'd appreciate some advice (and yes, I've read the FAQ!).

Thanks,

J.P.
