AMPEX MM-1100 16 Track

I just scored an Ampex MM-1100 16 track tape machine and need some help sourcing parts. it came with all the good back up stuff tension arms, ect,,, to much to list. one issue it the supply reel has a slight bend on the top at the knob turntable assembly and if I have to replace the motor that wont be easy to find. any help with leads or can i swap out the shaft? I'm new to 2" tape repair so please anything is better then nothing

Picked up two motors and a meter bridge couple months ago.
Thanks David. But if you have any other parts I might be interested (Transport Control PCB )

I’ll be following thread so please keep posting your progress. I’m he’ll bent on an Ampex mm1100 or 1200 or and MCI jh16 all discrete. Preferably an Ampex but people don’t let them go.

Just Sold the Ampex to a friend, picked up a JH16 (Older JH100)
Some think they are a nightmare but doing a total restore Harder to get parts, and many other issues. Model 0273 Year 1975

I track both for parts on the bay and I think JH16’s are easier to find parts for. You didn’t happen to buy the one on Reverb for $1500? I was watching that one. Too far of a drive from Central Texas or I would have jumped on it.

Nope. I live up in the northwest. But if you can find parts , looking for tha PLL Board for the JH-100 ... hard to find , not the newer. I’ll keep posting updates.

Blevins has 3 listed on their parts page. Don’t know how current the list is and they don’t list the transport they are for.

I spoke to Randy Friday he said the Newer Style PLL won't work on the JH-100 , but he said he might have one stashed somewhere. Waiting to hear back. Any other finds I might miss searching the net would be appreciated

What part goes bad on the board? I ask because I’m assuming I’ll be doing a full restore on whatever machine I end up with. I’m good with a soldering iron and recap and rechip a lot of my own gear. I was hoping the older machines didn’t have microprocessors and are all mechanical as for as the transports go. My Otari MTR 10 is full of microprocessors that I’m not sure once they go there will be no replacements to find.

My machine came with out the PPL card. Still hopeful that the guy I got it from can find it , he said there was a bag of parts somewhere and he’s looking for it but he’s a touring musician and always out of town. The parts are as you said , Caps, transistors, etc. IC’s can be bad sometimes from static electricity if someone didn’t handle stuff with care. Solder may need to be re-flowed on points if machine sits for too long.

How’s it going? I bought an 82 JH110B. It’s a test run for a 2” deck. I’m going through it with Steve Sadler via Skype. The first session I did with him I learned so much my head almost exploded.

Awesome. I’m an owner of a 77 JH16 as of a week now. She has a few quirks I’m gonna work out with Steve Sadler and then she’s getting recapped. Never thought I’d own a 2” deck and now I do.
