    Ampex 440C 1" 8trk Capstan motor

    When you say “MM100” do you mean MM-1100? The MM-1100 is relatively solid once it’s had the all the field updates implemented, which, in a coarse sense, essentially makes it an MM-1200. It’s also beneficial to upgrade the static guides to rolling guides. I’d have to look to see if the MM-1100...

    We just gotta figure out why it keeps blowing fuses.

    You’d have to correspond with John French regarding what’s actually available. I’m not sure how up-to-date the website is. He and I chatted quite a bit over the phone about the current situation earlier in the year. The conversation was spurred by the difficulty we were having sourcing a...

    I really don’t think so…Flux was the last one I know of making new heads but I believe Greg retired. So anything out there would have to be from any existing stock. I’d check with John French and also ATR Services. There are others I’m sure…

    That’s great. Not that there aren’t others capable of doing the work, but John and his wife are great people and JRF is my preferred provider for evaluations and service on heads and assemblies. He’s done some amazing work for me. Did you recap the plugin cards in the electronics at all? Do...

    In case you didn’t know the C has later gen heads on it with about triple the number of laminations (thinner laminations) and better HF performance to go with it. The earlier generations sound great but the C has that edge.

    Ampex 440C 1" 8trk Capstan motor

    I don’t think you understood what I was saying. There’s no way there’s a DC motor setup here. I only have a few small AG-440 bits and pieces. You’re going to have a hard time finding a DC setup, and it will be $$$, and may need repairs…and those will be $$$. I wish you luck.

    And I wasn’t saying the AG-440-8 can’t handle 1” tape, I’m saying ghe AG-440 transport wasn’t designed to do it, and they had to add components to it to get it to operate acceptably with 1” tape vs being designed from the ground up to handle 1” and 2” tape like the MM machines. The deck plate...

    Ampex 440C 1" 8trk Capstan motor

    I haven’t owned an AG-440 for about a decade and a half…I might have some random parts somewhere around here but certainly not a hen’s tooth complete servo motor setup. I wish you luck. The DC capstan didn’t necessarily provide better speed control. It provided the ability to interface primitive...

    I just saw your latest post. Can you please read/study my last post above and repost what if any of your questions remain?

    The AG-440C-8 has its own manual, as it should. The earlier versions had a supplemental manual to be partnered with the standard 1/4”~1/2” AG-440 machines. Here’s the AG-440C-8 manual...

    The box may also be the servo assembly with the power supply. To what socket on the control box does it connect?

    Ampex 440C 1" 8trk Capstan motor

    No such thing as an AC servo capstan…it’s AC hysteresis sync. The AC motor was an option on the 440C. The DC servo capstan was standard. That box I think is the servo power supply but I’m not sure.

    Tascam 38 Capstan Assembly Making Strange Noise.

    The 38 is designed to operate vertically, horizontally, or anything in between. Your capstan flywheel is rubbing on something, and when you have it laying flat the flywheel is resting fully on its thrust bearing. There is supposed to be a spacer washer between the flywheel and the back of the...

    Does it do it if you tip the machine back or forward while playing? Be careful doing this of course…heavy machine…don’t want it to get away from you. I’m a ways south of you.

    Tascam 464 and 488 head base pressure spring / plate - how do you get this part out?

    It literally took me 90 seconds. I have some. 244 transport carcass…capstan motor mounting screws…same exact screws. Send me a PM, Daniel.

    Tascam 464 and 488 head base pressure spring / plate - how do you get this part out?

    Ohhhh okay…the bracket is a pass-through to the motor, and the threads in the motor chassis are okay. Alright. Let me see what I can find. Worst-case scenario I have a really good local hardware store, walking distance from me, with a really good selection of metric hardware…as a fall-back.
