I'm more to incline to think its a b stock manufacturing that didn't pass. Which when Shure was in the US, they relabeled their B-stock and sold it to Realistic/Radio Shack. Because that style of manufacturing of finish on the threads, it would be coated and the threads cut, then later...

You do have a point with this as most are 5-12V internally set by a zener inside. But as far as building mic preamps, I think people should ditch the phantom circuit all together as its a point of loss. But this user I guess is trying to power a mixing board channel strip. Which could be easily...

maybe a different approach with a zener diode like what the old TAB modules had. Considering voltage regulators will not have headroom. The other logical approach would be a boost converter on the +15 V.

It really makes me wonder if someone is counterfeiting or if the CCP confiscates a manufacturing lot from a factory or distributor in China and the CCP is dumping it to upset the market. I know they do this to some who don't put 'made in China' on their products they manufacture there but...

To give you a serious answer, its the arc formed when mechanically switching. A suppression condenser, which that is the long name for it, is a constantly charged capacitor that lowers the potential voltage where the two points break contact.

Problem that I can see the OP needs to use a bigger transformer because 36V rectified to 50VDC is only going to leave 2V of headroom on the regulator so the only regulators that would work would be LDO types but I think all of them in the input voltage range are surface mount now these days. I'm...

Never had any issue with using 32 ohm AKG and 60 ohm Sony headphones, but I noticed my 250 ohm do have more bass to them, but the DT880 are semi-open back so they are going to have more bass naturally. 100 ohms might come from the output op amp's specification. So it might be able to drive a...

They were designed to be used as a headphone amp. I use them patched as mono and use a single aux send. But what you wanted to do has to be done with either a mixer or an interface that has a mixer before conversion and so far that info is not provided what interface is used.

I heard of people trying that out. But what I have seen them settle on is resonate head live and without when recording. Another interesting one is a resonate head tom with a a half dozen or so cotton balls in them.

What I find interesting is the layered effect of kick track without the resonate head and a track with a resonate head. Not many times I heard it but i do like it. The difference between the two, the one without the resonate head actually sounds better when recording, However, live, the mic...

Thank you. I didn't want to tell anyone about that. Hopefully soon I get some of my eyesight back through surgery. Because I had to find a new doctor and had to go back to the VA and after two years, I finally am in line to have something done. I'm pissed off at a lot of things in the world, but...

Well, if I wasn't almost blind I would be and IF there was a job available. Btw, I misread the schematic earlier, but I corrected my statement. This happens when I have get help and have to draw it in my head after someone describes it to me what is on the screen. I apologize that I don't have...

Honestly, you need to take some classes, and read more books, because the schematics you provided uses a resistor/cap for negative feedback in the cathode circuit. The output stage of the walkins dominator is a hifi output stage. Usually tertiary winding outputs are usually in rack equipment and...

btw, I book marked that link. I'll go over them thoughtfully eventually. Tube amps are an old thing to me. I went to a specialized college a few decades ago to learn consumer electronics. I just wished I had copied the in classroom textbook they payed Neve to make that went over parts...

you still on ignore. I was replying more to post 124 than your nonsense, that I put you on ignore in the first place over. Most .tube amps will have it. Because its the only thing that is keeping them from self-destructing operating tubes way out of their range. Others like the VOX are hifi...

analog recording did that until you got up into neve, amek, and ssl equipment. Because the lower end normally have a slope somewhere between 12-15K and the high end equipment rolled off at 100-200Khz electronically. The API desk was some where in between at around 50Khz, 500 series modules...

I think the hearing loss thing is skewed garbage science. Because everyone's hearing response changes differently for several reasons. Most of the mastering engineers retire around 80 and if age was a factor, then all those engineers wouldn't be 60+ like 3/4 were this past few decades.

Only times I was requested that an xlr should not have phantom power running was one time I had to di a pedal steel that the musician made a non-isolated DI. Other than that, I never had a mic that self destructed by phantom. However, I always find it curious why there is no DC coupled mic...

Technically, the VOX AC30 is one of the few that don't have a global negative feedback that other guitar amps misaligned to make it have poor speaker dampening.

The word condenser usually referred to a power capacitor or a capacitor that is primarily charged. But in the instance of the microphone, it has to do with charging the diaphragm.
