The Secret Society of Lathe Trolls

Dear All, excuse me for being lost: i didn't get notifications but now i turn this option on. Since august, I burnt a lot of EX 30S with high power, looking for higher gains on the record, and then I decided to switch back to KNOP's original setup with the Visaton BF32 membrane speakers. They work o...

Hi, i use 462 synthetic and 462P. I used first the synthetic one, it lasted for 150 hours of cutting (with a lots and lots of short test cuts), before noises came louder on different parts of the vinyl. Then I changed to 462P whose sound I found much warmer, but some customers said that it's not pos...

Since that - my father in law helped me out to build a better contact between the exciter (i call it resonator speaker) and the torque with M3 16mm screws (see image), so there's no need to epoxy on the torque s...

Hi Grooveguy, yes, i just simply epoxy'd them. They're stable. Since that i burnt out both speakers (overheating... they shut down permanently around 48 celsius), so i'm going to reassemble it. I hope i can close the quality of the sound samples posted above, and then i'll be also proud to post them...

Dear Community, just a small add-on to the topic. I realized KNOP's construction with some small modifications: ~ using DC motor instead of stepper in order to have a smooth slide. I use a hand-cranked generator connected reverse. ~ the original plan with funnels is great, but a lots of the frequenc...
