MCI JH-618

Hey Everyone:

I just picked up an MCI JH-618, physically it's in good shape, it "works", etc... However, it's pretty dusty and dirty inside, and subjectively I don't really know it sounds.

Where should I start, to get this thing up and running. Since bringing it to my place yesterday, I have yet to even power it up, I am thinking that I should probably do a bunch of cleaning first.

What would you do?

Any help, procedures are much appreciated.

If there's no evidence of humidity, rust or dust bunnies inside the console/PSU... I can't see the harm in powering the console to see if it can pass signal on every channel... if noisy, might need to be re-capped... buy a can of CAIG/Cailube for moving contact parts and a can of CAIG/DeoxIT for connectors, switches & contacts.

I would pull all the modules and clean up the innards (both mainframe and inside the modules). Inspect EVERYTHING for signs of coke/beer/ etc spillage.

Hey you know... It wasn't so bad in there!

I took everything out, and vacuumed it out, and blew a bit of dust out the the modules, and reassembled it...

It's actually in the other room for where it will end up, so I don't really have it hooked up to very well, but I wired up some outputs for speakers, and a couple of inputs and got some sound out of it.

Just out of curiousity, since this is a less full featured board than I have previously used, what are some of the more common or successful mods that people do to these things? I have a friend with one with Neve Flying Faders and an API master section, but has anyone have any others?

There are two JH-636 desks here in town, and both have required recapping. Those desks run very warm and cook the electrolytics. Use caps rated for 105 degrees C operation.
