Default calibration of fostex g16s

I apologize in advance this message shouldn't be in here, but I need
some guidance.

Would anyone know of a person capable of doing this? I'm just a picker
who enjoys recording at home, however I have virtually no capabilities
in this area.

I've found some web resources on how to do this, but to be honest, I'm
afraid of screwing up the machine up & making it sound worse than it
does now.

BTW, I am in Central Florida.

Kindest Regards,
Wynn Osborne

Bill Vermillion is down there still, isn't he? He doesn't hang out here
much any more but I bet he'd be willing to show you how to do the alignment
procedure.

It's something you need to learn to do yourself since it needs to be done
on a regular basis, but it's not a hard thing once you get the hang of it.

See if Bill is still around.

It's a completely appropriate post for this forum, Wynn.

It takes soem gear and some practice but it's not really difficult. I
can certainly understand preferring to pick.

I've found some web resources on how to do this, but to be honest, I'm

Not likely if you took your time, but time spent calibrating is time
lost for music making.

Wynn - were you able to find someone who could show you how to calibrate this machine? I'm in the same bind - a friend of mine brought one over here, and I need to line it up.

Is that one with just two heads (erase and record/play)? Repro
calibration is straightforward - do that first, just like any other
tape deck. But record calibration, though in principle is the same as
any other tape deck, is a real pain in the patootie because you can't
see the effect of your adjustments until you make a sample recording
and play it back.

For example, the procedure for adjusting the bias is to record a
10 kHz test tone, play it back, read the meter, turn the bias pot a
little, record, play back, read the meter. If the level went down,
turn the bias pot back to where it was and a little further back and
record again. If the playback level is higher than where you started,
turn the bias pot a little further in that direction and repeat until
you've found the position of peak output. Then start increasing the
bias a little at a time, recording and playing back with each
adjustment until the playback level is 3 dB (or another value,
depending the the tape). Then do it again 23 more times.

If you have any hair left (it falls out with age) then adjust the
record equalization for flattest frequency response. Same procedure
only you don't need to find the peak first.

Calibrating one of these is an all day job.
