Well...since it appears from your short video clip that only some channels are making noise....I'm going out on a limb here ;) and I'll say it's the electronics on the channel cards.

Like I mentioned earlier....I hate to say it, but you may find that they've gone bad. If it's related to the Dolby S chips that are on each of those cards, you got no options unless you can find replacement cards...the S chips themselves are impossible to find.

You can try moving the cards around....take a card from a channel that's making noise and swap it with one that isn't.....if the noise follows the card, then you can narrow it down to the card.
If it doesn't follow the cards....then the problem is elswhere, but I doubt it.

Now it may not be the Dolby S chips, and maybe it's some other components on the cards, since usually when the S chips go, the channel is completely dead, but you'll have to run some tests to determine that.
Have you tried recording on those tracks that are making noise to see if you can get some audio recorded (along with the noise)....and then see if it all plays back too?
 
swapping cards? how would i do that?

hm hopefully the problem doesn't follow the card then!

but i haven't tried recording yet! i will do that as soon as i can and get back to you!!
 
You have to open the front panel...not just the flip-up controller, but the metal panel behind it....and then the cards pull out.....mmmm....I don't believe there's any screws to undo, but I haven't worked on my G16 in a couple of years now, so I won't swear to it, but even if there are, it may be just one it's pretty easy to remove the cards, just be as gentle as you can.
I would have to look in the manual to confirm if there are any screws holding the cards in......
 
alright awesome! i will get on that asap, thank you!
let's just say the problem does follow the cards, would that just mean those few tracks are unusable?
 
Yeah....you could avoid those channels, group all their cards or even remove them....but the question is how many of them are having issues.
Also, if it is related to the Dolby S chips....then I wouldn't be surprised of the other cards suffer the same fate at some point.

Anyway....first try to isolate the problem and see what you learn form that before we get too far ahead. It may not be the cards or the S chips.....but keep your fingers crossed.
 
is the card the entire giant green panel thing? or is it one specific part?

also i tried recording on it, track one works great!!!
 
Yeah....the "green panel thing"... :D

Do you have the operational manual?
Go to Fostex and download it.....if you have sync option in the back (look for MIDI I/O) , you'll also want the 8330 manual.
Not sure if they have also have a downlad of the full service manual...but you should have that too.

Everyone is quite clear. I answered a question in the original post, specifically about 456 tape. What I did not do is suggest that the tape was the source of the noise.
