This is the next chapter of the thread located here.
I am now the proud owner of an Ampex MM-1000 1" 8-track.
I got it for $300 along with literally a truckload of parts and gear...see the above linked thread.
I have yet to power it up. It uses a big twist-lock power connector and I'll have to go get one and make the cable, but my understanding is that the gal I bought it from did some tracking with it in the last couple years with a band she is has and it has been stored indoors in a climate controlled area.
Overview of the MM-1000:
The earlier MM-1000's like mine are basically a 440-8 with a monstrous console and a beastly transport based on the Ampex VR-1000 or VR-2000 Quad Video transports...it was a quick answer Ampex put together to respond to a new shift in the multitrack industry...a demand for higher track-count. They were available as a 1" 8-track, 2" 16-track or special ordered as a 2" 24-track. The 8-track could (relatively) easily be converted to a 2" 16-track so financially strapped clients could get into the MM-1000 for less money and then when funds were available they could move up to the 2" 16-track (or 24-track). The capstan was, like the 440, AC hysteresis or DC servo, but even the servo models are not able to slave in a sync relationship. Also like the 440 it is not a servo transport...in other words the reel motors don't "talk to each other" like a more modern full logic servo transport. BUT...the transport itself is just beastly...built to manhandle 2" tape on 14" reels.
What I Know About My MM-1000
My MM-1000 started out life as a 16-track but was converted to an 8-track. I lack the tape path parts to convert back to 16-track and I'm not sure I want to do that anyway, but (along with electronics from my 440-8) I have pretty much everything electronically to convert it back...there are pictures to come. Along with all the stuff I got in the thread linked above I got scads of spare MM-1000 electronic components. Mine has the AC capstan motor but the DC servo box is mounted in the console. Nothing wrong with the AC motor but the DC motor would allow 30ips...not sure I really care about that. Certainly not at this stage as it would require a 30ips cal tape and redoing all the eq cards...BUT...I may actually have a lead on spare 1" tape path parts, a full set of 2" 16-track tape path parts including heads for little more than shipping (making the door to 2" 16-track a near possibility).
My MM lived at Universal Studios in California, and ultimately fell into the hands of Bob Lawson, long-time technician and R&D specialist at Ampex. He also serviced Ampex systems for clients in the California area. For some reason this MM-1000 and a whole bunch of parts came to him and then ended up with his daughter after he passed away a couple years ago. That's who I bought it all from.
So because it was in a professional installation for much of its life (and because these things are too heavy to go anywhere anyway) it is pretty straight, clean and pretty much all there. No rust or corrosion...needs a little de-griming and kind of putting back together. Looks like somebody ran sticky tape on it as well as some flaky tape but the sticky stuff on the guides, lifters and some on the heads comes off easily. The heads by the way look great...little wear and I don't believe they have been lapped. I would be surprised if the heads were put on new when it was coverted to 8-track and then not used much after that.
So...without further ado let's get to some pictures. I'll be rigging a temporary power cord in the next few days and take it for a spin and see what I really have.
