The Secret Society of Lathe Trolls

Hi everyone, the machine is sold!!

For sale a Taunus Ton Technik machine, Germany, for the production of vinyl records, including press, extruder and control cabinet, in ready-to-use condition. The topic of transport is considered separately. The exact transportation costs depend on the customer's location.

I don't have FFT analyzer

. u should try to use an fft to measure or compare your distortions levels against another reference cut. you have a nab test record? i think you are still at square one. Yes, I still don't know much... Can you tell more about FFT? How to do it? I have no NAB test record, but here is: http://store....

I don't know why, but Muth's method of cutterhead calibration is not suitable for my system. After I did the calibration from the Neumann's manual it worked correctly. I think all the steps we made had a positive effect. Thank you all for your help. Good grooves.

I am in Russia, in Moscow.

Hi, Leo. This is my bad English. Sorry. I took the coil together with the head armature. Of course I meant capacitors. I did a calibration by Chris Muth's method with some variations (5kHz -20dBU). I generated a sweep (20-20000Hz), analyzed the monitor output signal in position FB, where I got an al...

Hi. Can't find his contacts. Do you have?

I agree with Leo. Wait until a professional can assist. But, to answer. BSB's are Acceleration Limiters (High Frequency Limiters) for cutterhead protection. Your rack might not have them. I have them. I wrote about them: ........ It remains to think that the acceleration limiters guilty. Is there s...

What is bsb?

Do not attempt to disassemble! Unless you know how. Don't. Hi. I did it. Moved the coil from one head to another. Now I have a head where the two coils with 4.9 and about 90 Ohms. Replaced the chips and capacity in sal74. Calibrated already 1000 times in various ways. Frequency response feedback is...

Hi! I want to find the schematic of Neumann SAB-74E 21665-141-A01 1661 and SAB-74E 21665-142-A01 1661. Please somebody help me.

Nothing has changed after calibration of both cutterheads. Still sibilants, where the high resistance of the feedback coils.

Maybe I want to become an expert))) just kidding. Of course I'm not going to risk it. It's just a new theme for me, all want to understand. Florian promises already 3rd month, but does not arrive for some reason.

Do you mean I must to buy a round wire and flatten it? Another misunderstanding in the disassembly is the piston rods that are glued? How to remove? And what kind of glue can be used after?

Any accurate 1k and 5k tone source and a callibrated VU meter, a test tone record, and a tonearm on your lathe is all you need. The calibration process is easy. Totally required. I think this will resolve your issues. However it should be noted that the calibration is specific to one head. If you s...

Thank you so much, colleagues. I will try...

Unfortunately I'm on another continent. I'm sorry, I didn't know how to measure. Now I did as you said. Cutterhead No. 729 has a resistance of 4.8&3.9 Ohm: https://youtu.be/p9qUXEEQqxc, cutterhead No. 653 has to 4.9&4.9 Ohm: https://youtu.be/0NGts3HUwAU About calibration: I think it was done a very ...

Hi, guys! I have a problem, need help. I must say - I'm new, many still do not understand. I have two cutterheads SX-74 with mirrored problems. One cutterhead has the sibilants in the left channel, the other in the right channel. Everything seen in the photos. What are the ways to solve the problem?...
