noise on a JH-16

how's it going guys

so, believe it or not I've got my JH-16 up and running with just my own elbow grease

seems like a couple channels are noisier than others,

how much can I fix through further calibration?

do some of you guys run these things through noise reducers?

I gotta be honest, a couple of the channels the hiss is unbearable

i doubt it's a calibration thing. most likely an op amp (chip) or another failure.

there's several things you can do to find the problem:

i'm not sure if you're having a noise problem in playback or while recording- so we'll start here-

1- switch modes. if the channels are noisy in cue, switch to repro or vice-versa. does it change? if so, there's your problem- either the cue or repro card (depending on which mode is noisy)

2- if there is no change- swap output cards on the channel. if that doesn't help, it could be a record (or bias) card actually recording the noise on tape. so switch record cards with another channel and see if the noise follows the card or stays on the channel. repeat the process for the bias card if needed.

3- switch speeds. does the noise stay at 30ips and 15ips?

these will help you narrow down the issue to one or two op amps or other parts.

good luck, and make sure you have your tensions adjusted right so you won't reduce the life of your head stack.

what's the best way to adjust tension?

also, i'm looking to get extra parts off a machine in town,

what would be in my best interest to walk away with?

(cards, etc.)

Get the entire parts machine!
If not, get one of every card including those in the transport.
I'd try to get the capstan motor and phase lock loop board as well.

The manual should have a rough calibration for tension in it.
You can still buy a Ten-Tel-ometer I belive.
They are the best device for setting tension accurately.

You noise issue sounds more like an op-amp problem.
I can't tell from the info.
If I could see the deck in person I could diagnose it quickly.
