The Secret Society of Lathe Trolls

You can laugh, and you probably should, but mine is made of one of these plus a few bits of PVC piping. Fits right in the stock holder.

Excellent!

Silence is golden. Move it out of the room and you'll never go back.

I'm running 2" hose about 20'. 100's of feet would still be fine. There's very little airflow so distance barely matters if the system is air-tight. And whatever difference there is can be compensated for with the variac.

I don't, but when you find one, take extra care to match the run caps to the system. Mine was converted from 50Hz to 60Hz but they didn't change the run caps so the whole system was fighting with excessive motor vibration and running hot. I changed the caps and it smoothed everything out nicely. Her...

Well done!

I built a similar unit but it triggers on audio tones rather than MIDI since my DAW (Wavelab) doesn't support MIDI. It's a fantastic addition!

Be careful with the cheap ones. Some run at a fixed pitch and are far, far worse at everything than even a modest pivoting arm.

Cool!

If they play that is too cool!

Maybe Kindercore or NORP?

Yeah, I think we ALL know who that is...

Those times will be fine at 33. A bit long for 45, IMO. Level we be determined by distortion as much as length at 33.

Mono gives you a slight advantage since there is no added lateral movement due to vertical content. IOW, slightly better LPI economy. But not the deciding factor.

I use this scope: https://www.ebay.com/itm/AmScope-SE306R-P20-40X-80X-Student-Binocular-Stereo-Microscope-with-Dual-Lights/190806743602?epid=2255361850&hash=item2c6cf7da32:g:QagAAOSwQcZbmYwg I've used the Neumann scope but the resolution on the one I had was not great.

That's pretty damn funny!

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.

Just re-read your post. You also may have bent a leaf when you were cleaning it. Those things are notoriously touchy. Check there as well.

I had this exact problem a few months ago. In my case it was the wiring harness between the suspension box and the head. The strain relief had broken on the head side and many of the wires were frayed. Once one of them finally failed the circuit breaker saw an open circuit and popped the breaker. To...

The vast majority of studio recording is done with mono mic techniques so the stereo most people are familiar with is panpot stereo. The stereo effect is due to differences in level between the left and right speaker and will usually look very narrow on a correlation meter. Most classical recordings...

Or matrix quadraphonic (SQ, QS, EV-4, Dynaquad...) or a stereo test record from 1956-7.

Or a classical recording.

What does it sound like? Lots and lots of music has wide, uncorrelated stereo content. That's what makes it sound wide. Not a flaw. A feature. That's how stereo works.

Let's assume it's correct until it sounds wrong, not when a meter looks funny.

Bruno's words, not mine. Who's Bruno?

These aren't really digital amps anyway.
