The Secret Society of Lathe Trolls

I stole the circuit breaker (And series RC to compensate driver inductance at high frequency) from the SAL74, and sort of reworked it a bit to take advantage of modern doings and to make it run a better model of voice coil temperature as a function of current and measured value, got to love how eas...

Well if you are the cutting engineer, you need to educate them! I do remember in the old days, the cutting engineer would shake his head and send you away. Unfortunately the people who wrote those checks to the cutting engineer are no longer writing checks. If you want people who are alive to write...

Is there more resistance on the slide where the problem occurs? Is the slide well lubricated? When you fast wind over the problem area is the action as smooth as other spots? Those are the first questions I'd ask. I'd look for a mechanical issue first and then look for an electronics issue. It could...

I have done them before. I can do it.

I believe the silicone oil specified was Dow Dowsill 510 50cs

I use a Neumann VMS suspension box, they never specified what grade to use, but 3 in One oil works perfectly and it doesn't weep all over the place! The original oil specified was Telus 29. They then specified a silicone oil who’s specs I forget. Telus 29 is impossible to find although I have a goo...

I am looking for the gear trains for an AM-131. If anyone has automated their lathe and don’t need them anymore I’d like them. My AM-131 was changed from fixed pitch to continuously variable manual pitch with motors and belt. I would like to set it back to stock but the gear trains are missing.

Do you have a cutterhead with electronic feedback? Can you set up a feedback monitor? You need to know what the cutterhead is doing before you can set up the playback. Comparing playback to the source file won't work because what's getting cut is different than the source file. If you don't have ele...

I was thinking of US domestic 220vac which is two 120VAC 180º out of phase with Ground in the middle. Free balanced power.

If you are unsure then you should find someone to help you. Mains wiring can kill you. It's nothing to play around with or have done improperly.

if anyone actually knows what theyre on about and would care to enlighten me, that would be awesome.... if not i'll keep trying to suss it out. Are you in 230VAC land or 120VAC land? If you are in Europe the the two coils that form the Primary should be in series. If you are in the USA then the two...

This M10A is a "B wind" deck where the tape oxide faces out instead of in. Telefunken/AEG didn't make audio electronics for this model. In the SP66 console which has an M10A deck built in, the audio electronics were made by a third party whose name escapes me. It looks like there is a power supply i...

I am the proud custodian of the Gotham Audio lathe schematic library. I believe I have every version of every drawing ever produced for the VMS66/70 and the VMS80. I don't have complete documentation for earlier models. I am offering custom hard copies of manuals to match the individual rack or lath...

This working programmer is set up for 7" and 12" 45 RPM. It could be changed to any three diameters and any one speed. Schematic included. Alternate setup for an additional fee. $1250. http://www.saltmastering.com/ForSale/IMG_0925.JPG http://www.saltmastering.com/ForSale/IMG_0926.JPG http://www.salt...

That looks like an eight channel 1" deck. There was no such thing as a 1" 2tr let alone preview deck when that was built. I understand Scully did manufacture a preview deck but I've never seen one. It would have been a 1/4" deck.

Still available. Sure, make me an offer. Email is best paul at saltmastering dot com

GGR did the hair record. I thought it was likely Erika did the string one so I asked. Yep Erika.

Thanks guys. I'll give a shout to Matt.

Title says it all. One has hair pressed into it and the other has yarn pressed into it.

Audiophile is a state of mind. It's separate from sound quality. When how it's made approaches the importance of the sound coming out of the speakers then the tail is wagging the dog. That. The word generally garners a negative response among pro audio type people. The crowd over at DIY Audio consi...
