Otari MX-5050 MKIII-2 Static

I have a total beginner's question for the group. I recently purchased an
Otari MX-5050 MKIII-2 reel-to-reel deck in order to transfer a large
collection of family recordings to CD. The deck is in excellent condition
and all functions seem to perform as expected. There's one thing that does
worry me, though. Perhaps I'm just paranoid, but it seems like it
produces a lot of static (hiss) just by having the power on. Without
playing a tape, there is the same amount of static if I listen through my
headphones connected directly to the deck as there is through the rear
outputs. So the problem seems to be internal. Is this normal for an older
piece of equipment such as this?

While searching through Google News concerning a problem I came across a
post from way back in 1998 which I think might have a bearing on my
problem. Here it is:

Thanks for your help.

Static and hiss are not the same thing.

You probably have the volume turned all the way up. Regardless, the only way you
can know for sure is to ACTUALLY PLAY A TAPE.

Stop theorizing, and DO SOMETHING.

Wow, what a friendly reply. :) 

Yes, it plays just fine. I have the Otari hooked up to my Layla24, and am
able to record to my computer. I was just wondering if it is normal for an
older Otari reel-to-reel to generate a considerable amount of noise all on
its own.

without some quantitative information from you we cannot answer the
question.

using a meter (or your soundcard) play a standard level test tape. establish
a level (like zero dB).

next pause the tape. measure the level... is it -40 dB? -50dB?

then compare to the specs listed in the service manual.

if you don't have a standard test tape you can use a test tone as the
reference.

I'm sorry if you're offended, but people too often ask questions without having
actually gone through the basic steps of testing something, and their postings
leave out 90% of the information needed to make any kind of intelligent
assessment. This happens over and over and over and over and over again, in this
and every other UseNet group.

Basic answer... If you're playing a properly recorded tape (that is, its peak
levels hit 0 or a bit higher) at a normal listening level, and you hear audible
hiss when the tape is stopped -- yes, something is almost certainly wrong with
the deck. A paused or stopped tape deck -- be it open-reel, cassette, or
digital -- should not produce audible noise.

Static is not hiss. These are two different things.

Whether or not you have too much hiss depends on whether you can hear it
with signal. If you play back a blank tape, and the tape hiss is much
louder than the recorder noise floor, everything is fine. If the recorder
noise floor drowns out the tape noise, it's not.

I strongly suggest you do a full alignment on the machine before you make
any judgement about noise, though. If the playback level and EQ aren't
set right, noise will be exaggerated.

If you have quarter-track heads on the machine, you can expect the noise floor
to be a little higher than if you have half-track heads just because the signal
coming off of the head will be lower.

True. But he's saying the deck is audibly noisy even when the tape isn't
running.

Yup. But if you crank the level control all the way up and you crank the
high end EQ all the way up, you'll hear all kinds of noise when the tape
isn't running. But, this is not the normal state that the machine should
ever be running at.

That's why I asked whether he actually played any tapes. (He hadn't said.)

I'm curious as to what sort of component failure could cause both channels of
tape deck to become extremely noisy.

Well, it's correct. If you push anything electronic beyone its normal
operating range, you're very likely to hear an abnormal amount of
noise.

It's perfectly normal for anything to generate noise, and if you
amplify it by turning the volume up well beyond normal, you'll hear
that noise. If you want to try an experiment which may be destructive,
turn the volume up to the point where you find the noise to be
objectionable and then start playing a tape. You'll probably blow out
your speakers or headphones. If it's sufficiently quiet at normal
playback levels, it's fine.

If you have switched mic./line I/p's make sure they are switched to line
& turned down.
Might also sound noisy if you are using balanced outputs wired
incorrectly.
