The Secret Society of Lathe Trolls

Out of the many different ways and places in a chain where you can measure levels, which ones do you find useful to look at while cutting? 1. VU meter before the RIAA 2. Peak meter before the RIAA 3. Lateral/vertical meters before the RIAA 4. VU/PPM after the RIAA 5. Voltage across the head 6. Curre...

Bryan, my main intention for making this public was to protect others from being scammed in the same way. I did try to discuss this in private with Angulo for around 1 month of constant email communication on my part. I eliminated every possibility of this being a mistake or misunderstanding and Ang...

My surplus has now been sold. These are no longer available. I will keep you updated when I have the final product ready.

Well, at least you are good in lying, Angulo! Nobody can be all bad in everything... I did sent you dozens of emails since I received the cutter head telling you that I am not happy with it and very politely requesting a refund. I have never threatened you and I have never blackmailed you. I never a...

Interesting information. I have also heard of one DIY head with no torque tube although the maker said that it would probably be better to modify the design to include a torque tube for the stereo separation. The lack of a torque tube is the least of the problems with Angulos head. The fact that the...

According to an old book I have, embossing was widely used in the past for vertically modulated grooves. This was mono of course and it actually seemed more practical to emboss vertical modulation rather than lateral. The shape of the groove depends on the shape and angle of the embossing stylus. If...

How exactly did I threaten or blackmail you, Angulo? The only money I ever asked you to send me back was the exact amount I paid you for your fake cutter head. Making such unfounded claims about me does even more harm to your reputation and it is also illegal. The reason you are failing in keeping a...

Angulo, you are in no position to insult members of this forum. The appalling quality of your products is evident by the pictures posted here, by your photoshoped photographs on your website, and by your fake videos. Apart from a terrible engineer, you are also a thief. I have requested my money bac...

If he really believes that what he makes is actually really good, then I guess he will soon be singing about a very happy place...

60 k ohm output impedance??? What would you drive with it? Ideally, for most audio applications you want a high input impedance and a low output impedance to prevent distortion and hf loss. Older studio equipment used the standard of 600 ohm both for output and input impedances, which also works. So...

I really dont know why you buy from him, he talk good with you? because with me, his first talk make me send him to hell... Before sending him any money, he was by far the most communicative and talkative person selling anything related to disk cutting that I have ever met in my life. This quickly ...

When I was asking around about Angulo, I was left with the impression that he had been selling his products for nearly 10 years but that nobody in Europe or the USA that anybody knows of has tried them. I am now seeing that his own website only seems to exist since 2 years or so. Does anybody know f...

Mark, I am aware of this. It was his specification claiming the 9.5 amps of current for 10 seconds and he mentioned the head to me even in his invoice as a 500 W rms cutter head. For a cutter head advertised with such specs, I would at least expect some sturdy purpose made coils instead of a a pair ...

As an indication, one of these circuits with no connectors or box would cost $ 30.
So, two channels for stereo would cost $ 60 with no connectors or box.

The rest will depend on the cost of the materials and the amount of time it is going to take me to drill the holes and put everything together.

Hi Jesus This is fantastic I love experimenting ! How much is the modified lipshitz in stereo female to female RCA ?? Dimi Thank you for your interest, Dimi. The connectors are secured on a panel from the outside, while the circuit sits on the inside, this means that the connectors have to be solde...

To not get carried away in discussion, I am posting some hard facts. This is the specifications as they appeared on Angulos website http://www.angulorecords.com at the time of me ordering the head (google translate from Spanish): -system Depression angle transducer 45/45, degrees Frequency Response ...

Dear trolls, I am in the process of developing an RIAA pre-emphasis preamplifier for disk cutting. We started by building the reference RIAA pre-emphasis networks described by Lipshitz in his AES paper and by Hagerman on his paper available on his website. The purpose of this exercise was to test th...

Used https://translate.google.com: Estimado Angulo, Por favor, tomar acciones legales. No puedo esperar para que usted tome acción legal. No se moleste implicando el foro, hacerlo contra mí personalmente !!! Se necesitaría un infierno de un buen abogado y más dinero de lo que nunca soñar con tener q...

Dear Angulo, PLEASE, do take legal action. I can't wait for you to take legal action. Don't bother implicating the forum, do it against me personally!!! You'd need one hell of a good lawyer and more money than you would ever dream of having to bribe corrupt judges to win such a case. Which one of th...

The lubricant on the record mainly acts to reduce surface noise and prolong embossing stylus life. I do not really have experience with turntables with no counterweight or anti skating. As for anti-skating, aren't skating forces on polycarbonate more extreme than on PVC? I always find that I need to...
