Neumann KS70 cassette for next donor to give 70 USD

Another cassette is offered for the next donor of at least 70 USD to Lathe Trolls. The KS70 cassette for Neumann SP consoles is used for automated cutting where the number of titles is entered and it does something for this. By preselecting the number of titles, I suppose?, it ignores the last segme...

Re: Neumann Digital Timer

Looks sweet, Paul. Is it four channels on one switch, again, or do I need two (or 4!) of those "beauts"?

Re: Neumann Digital Timer

Now glowing, and counting , in Dietrich's old SP 272. Just had to fix the start/stop switch which had a broken internal contact. The thing seems to handle either 110 or 220 vAC indifferently, other than the intensity of the lamps. But the logic gets a steady 5V, either way. Cutter's egg timer... htt...

Has frequencies for calibrating the preview path (includes 200 Hz). Probably not working, but included with the cassette will be the original schematics, ...

Re: Neumann Digital Timer

I found a blurb on the SP79C_Data-E.pdf (search with Metacrawler.com) which might be explaining this, although the one I have reads, DSU 74, and came in the SP 272 (disc cutter's bar-with-ash-tray).

Ok... These are hard to get info on. I found so far nothing on it in the Neumann manual CD-ROM from eBay.

Re: 100% correct stylus heating

Hi, Unfortunately, adding heat during a cut is flirting with both chip fire and the very horning one is trying to preclude by heating the stylus in the first place. One trusts the current meter for reference, but the only way to verify that the heat is not too low is to do a test cut on the lacquer ...

Hi TubeFan, Actually, Ortofon recommend [H] over [He]. From the Ortofon GE/GO 741 instruction manual, p. 3: " Cooling During recording, the cutterhead [sic] may be filled with a good thermal conducting gas. Hydrogen is best suited but for safety reasons, helium is often preferred. About twice the po...

I had a similar issue on the new LS-76 where the tt wouldn't stop even when the pushbutton was unlit. I had noticed this mode of misbehavior once before while working on the older LS-76 tt servo drive board. There's an op amp, 5534, which can function for other signaling, even if one of its legs is ...

...let us know if ye search parts for GE/GO 741 or DSS cutter or L. J. Scully "The Lathe" parts hard to find. We have some inventory, now, so can at least consult on locating/cloning some items and have good partners in searching for parts in China, USA, and Lithuania. Have a great session!
