Re: stylus heating question (plastic)
Here is one I made earlier... 6 or 7 turns on that one, but you get the idea: https://www.instagram.com/dubstudio/p/CEb48Z1BhRS

Re: stylus heating question (plastic)
Not exactly. OK so the method I use is as follows: 1) cut off a couple of inches of wire (length = 2 x distance of stylus from binding posts, plus 8 x windings, plus a little spare at each end to hold on to) 2) mount the stylus in the head 3) tie one end of the wire to a binding post, leave a littl...

Re: Caruso parametric curve
i would listen to the guy who designed and make/made the Caruso heads ;) Of course, I am not disputing anything Flo says, but I think its important to draw the distinction between using pink noise to help quantify and verify any adjustments you make and using pink noise to correct a cutting head to...

Re: Caruso parametric curve
What’s the best way to further correct the carusos frequency response? It’s close but needs some correction. Is it best to run white noise and auto correct with a eq matching plugin both channels at the same time? Maybe one channel at a time? Maybe not using a matching eq but just manually add more...

Re: Caruso parametric curve
I would think a single impulse measurement would have a very low S/N ratio. If you average many impulses you can improve the S/N , but that's not so easy to do. I guess if you window out the single impulse to be very short in duration, you would effectively filter out all of the low frequency noise...

Re: Caruso parametric curve
I would go very slow.cut some stuff you know and where you have the master and a reference on vinyl. listen on a decent system you know.compare and and do slight adjustments.. the fab filter .pink noise is the wrong way to go. Technically yes .but soundwise very bad idea… You don’t have to dream. C...

Re: Peculiar surface noise cause VR
Can you record the noise and post it so I can hear it?

Re: Caruso parametric curve
When testing real-world response, I tend to record an impulse (one sample) and measure the response with EQ matching... that way you don't get all the surface noise and TT rumble skewing the result.

Re: Weird bass sounds/skipping on T560
If it's the stock 1200 turntable, I'd guess it's a torque issue. I have never noticed torque creating stability issues (other than wow and flutter) so I would be surprised if that's the cause. In any case, you need to do the resistor mod to get good results with a Technics 1200 / 1210 so I would lo...

Re: Weird bass sounds/skipping on T560
Audio is also ok because it happens even when I cut silent groove. Ok this is an important bit of information which helps to narrow down the list of potential causes.. it's definitely mechanical. Temperature should be probably ok, I cut around 40-42 celsius of disk temperature. This could be the ca...

Re: T560 Overhead motor
Hm, its quite common for that to happen, and it shouldn't damage the clutch. It's more likely to be an issue with the lead screw itself. When you wind it back, the screw has to lock back onto the nut, so perhaps its cross threaded, or there is some grit / swarf stuck in there. I would try running it...

Re: Weird bass sounds/skipping on T560
BTW the above answer covers all the possible causes of low frequency skipping that I can think of at the time of writing... but looking at the picture it looks like its mainly a disc temperature issue.

Re: Weird bass sounds/skipping on T560
This could be chatter, “humping”, subsonic frequencies, too much stereo width.. the list goes on. Without seeing the lathe set up, inspecting the disc, and hearing the audio, it's hard to say. But here are some pointers: When the stylus hits a warp in the disc, like a car hitting a hump in the road,...

Re: Anyone know any <200 turntables with lots of torque?
Interesting... strobe sdturggling how in what sense? It's not 100% solid. It moves a tiny bit back and forth (by a tiny margin ), but the rotation of the platter is stable as hell according to the RPM app (wow and flutter values are also low)... This could be my SP too. I have a recapped BBC versio...

this seems to be obsessing with what lacquers are called...this paper might have some interest back in the 70's ,but I don't think now...

I wonder if I could ask where the photo of the 14-B came from? Is there any more info out there about it? Larger res photo?

Re: Anyone know any <200 turntables with lots of torque?
@Dub Studio - I am currently cutting with SP15. It has been freshly serviced. It can withstand around 70 g of weight. I also have a sp10mk2 and this can withstand easily around 500g.. Did a very non-scientific test. I bought myself a digital scale spoon (for spices and such). Placed a phone with a ...
