They are looking for a Neumann 74 lathe?

Is there such a thing?

Maybe looking for the head...I get it.

Well, they _did_ say, "... Neumann 70/74 mastering lathe..." I take this to mean VMS70 w/SX-74 head, yes?

Yep, took me a minute.

[Serif]

They should have called it a 70/74 system, rather than 70/74... lathe.

Looking for a working VMS80/Webster Electric (w/Brush pickup) system; sky crane delivery only, please...

The lathe is called a VMS70 but it wasn't produced and sold until 1974. Possibly that is where the confusion comes from. Some parts have 74 in their part number to reflect that fact.

The only lathe I am aware of from Neumann that had a subversion is the 80's model. There were VMS80 and VMS82 one for lacquers and the other DMM.

The VMS70 was introduced in 1970. The SAL74 was introduced in 1974.

[opcode66]

Ahhhh. My bad. I was under the impression that both the p/d comp and the amp rack were both from 74. So, the original units that came out in 1970 came with the 60's SAL rack?

[gold]

The first VMS70's had the gray case but the slide and VA box were VMS66 green. The Master Cutting Room lathe which is now a Korean turntable was bought off the floor of the 1971 AES show and looked like I describe. They were supplied with a VG66 drive package and an SX68 cutter head.

[opcode66]

So, really, the first 70's models were just the 66 electronics in a new case. The actual lathe body was only slightly modified but otherwise looks very similar to the 66. Suspension is the same. And, then in 74 the updated electronics and head were released.

[gold]

The VMS66 and the VMS70 are functionally identical. It was just a cosmetic change. You can exchange every part. Just about the only difference is that in the 70 the location of the power transformers were moved.

I prefer the look and build of the VMS66. The frame is a little sturdier.

[concretecowboy71]

There are even small and subtle differences in the two VMS70s that I have.

The buttons on the far left for power and motor are in a different order, the underside of the turntable ring is tapered on one machine and hard 90 degree angle on the other. The knob that controls spiral time has a function when you set it to "sec" that puts a VERY short spiral and the second lathe you cannot even put the knob into that position.

Light bulbs are almost maddeningly different from lathe to lathe. I have found I think four different types between the two machine already.

Just a few of the things I have noticed so far.

They are all a little different but almost every sub assembly can be exchanged.

That's a calibration thing. Try swapping programmers between machines and you will understand.

[concretecowboy71]

Thanks Paul!

The calibration for that is the "sp" pot on the controller box, correct?

Do you know what the function of the setting called "sec" is on that knob?

I like using it for when I just need a very small track band say on a 12" 45rpm or a 7" 33rpm.

I found out my #2 lathe will go into that mode but you have to turn the knob counter clockwise....my other lathe, you turn the knob clockwise!

[gold]

Correct.

Do you know what the function of the setting called "sec" is on that knob?

Just another position. It looks faster than 0.25

I found out my #2 lathe will go into that mode but you have to turn the knob counter clockwise....my other lathe, you turn the knob clockwise!

Are you talking about P11 Sp on the programmer? That's odd. I'm not sure what you mean "go into that mode". It sounds like something is not working as it should.

[concretecowboy71]

Oh no, I just meant to get the time selector to go into the "sec" position.

On one lathe, it clicks in after .25 going counter clockwise. The other lathe, you have to go clockwise from 2 to get there.

Just a small worthless observation as to how these things are the same and interchangeable but slightly different.

The limiters were posted for $1 start price a while ago, now he has re-listed these for 1500 start price!

If there were this many eyes on it and nobody bid for $1, why $1500 now?
