... May I suggest IMHO, that testing amplifiers with "square waves and a wide range of capacitive loads" is an artifact from the 60's and, though still...
I've just had another look at the Senheisser data for these. It is a fig 8 with central diaphragm and 2 separate backplates. Using a standard JFET circuit as...
Hi, ... I have no LF instability problems, I do use other loads, bith a less large number of test signals. ... Amazing how many others are. But I tend not to...
... Look for differential capacitor circuits -- there's a transformerless one that charges both sides fast to a reference voltage (oscilator and diodes) and...
Hi, ... Then I suspect the strong tendency of the AD797 to turn into an oscillator at the slightest provocation, or even without any, is proof of the actual ...
Hi, ... One would, but I suspect the designer was referrenced in the Alanis Morissette song 'Ironic' (as Mr. Playitsafe)..... ... I have seen it in valve...
... for ultra low noise circuit for a moving coil pick up in the files section. it uses medium power transistors as input devices to get low noise. So you did...
... Thorsten, I know you don't like them but for those of us who insist on using crap bits to get super performance, could you give us what types came up best...
... Would anyone who has loadsa old copies of WW please dig up guru Baxandall's RF circuit. 70's or maybe late 60's even. He gave full details including his...
Hi, ... There are no quick and easy answers. In coupling applications we verified the results of Jung/March but extended their circuit slightly. That means...
Thanks for all the capacitor info. I am surprised that I never see anywhere a test procedure for evaluating capacitors to be used in audio circuits. I guess...
Hi, ... One problem is that at times what translates into audibly better is not always distingiushable by traditional tests and not many non-traditional tests...
... The complete quote is: "When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot...
Thanks Eric! First, for the quote since I did not remember where I read it and for so well expressing the concept. I like to understand the pros and cons of...
Hi, ... True. However, if you understand most issues that you can measure and how they relate to how it sounds, some remain, that are not (yet) quantifiable. ...
I have spendt a good deal of time working with the mkh design. It is a simple two transister circuit. The hard part is that is also two transformer. I would be...
From: Thorsten Loesch Sent: Saturday, September 02, 2006 10:41 Thanks Thorsten for the reference. ... "non-ideal" property in a constructive manner. ... ...
Hi, ... Non-infinite capacitance..... ;-) ... Interestingly, much has actually been written at different times about this (and other such phenomenae), in...
... Wireless World was THE premier electronics magazine from the 1930s till the 1990s (I think). As respected as Bell Systems Technical Journal. Arthur C...
... Thorsten, have you a reference to the superiority of Tinfoil types? Is this the result of your own (and your friends') research? Which manufacturers use...
i have also often dreamt of a low cost simple transformerless replacement for the mkh circuit (i have an mkh capsule and 805 body with me). one thought was to...
Hi, ... This was the result of several rounds of listening tests over time. I actually found some Silver Foil & Mylar types hand-made in japan even better, but...
What is the actual operating principle? Is the oscillator driving a tuned circuit which has the microphone element as the tuning capacitor and the circuit is...
Hi, ... It is basically a simple FM transmitter unionised with an FM Discriminator (demodulator). ... Well, nothing prevents it form having hugely greater...
That is a fact that it does have a very high dynamic range. I use the mkh-110 from 5 cycles all the way to 40,000 cycle bat calls. The unbalanced mkh-110...
Hi, ... Anyway, that is what it looks like to me.... ;-) I may be wrong. Still, looking at the MKH30 circuit I see no other really frequency determining...
