Equaliser for Shure V15III
 

Don Pearce the Lying Asshole

I did the simulation two years ago and the results are still he

http://81.174.169.10/odds/v15iii/cartridge.html



** I tested using a ** REAL ** Shure V15III - owned one since
1978, long out of use now.

No peak around 10kHz is created by adding 200 pF (or even 400pF ) to
150pF with a 47kohms load.

Proves yet again the absolute folly of naive simulations.

Fools like Jim Leserf and Don the drongo you are world champs at that
fake art.


You never made any such measurement.


** You are nothing but a CRIMINAL LIAR - Pearce.

Get a real V15III and find out how wrong you are.


In fact you have never produced the slightest shred of evidence that you
have ever done anything in your life.


** There is no-one so blind as a congenital, lying pommy ****wit who refuses
to see.

So we are to believe that a) Shure don't know the electrical
characteristics of their cartridges, or b) the laws of physics have been
suspended especially for them, or c) you got it wrong again. I know
where my money is.

I'm trying to improve the frequency response of my
V15III/SME 3009 S2, and remember that Shure or SME had a
little equaliser circuit that flattened the response at
the expense of a couple of dBs of output. Something may
have been published in HFN and/or Wireless World in the
'70s, but my HFNs don't go back that far, and I can't
find it in my WWs of the era.
I've been searching on-line for the circuit all
afternoon, and can't find anything. It was simply a
capacitor and a resistor or two, but I can't remember the
configuration or values.

In the day of, I was a V15 fan. I owned a number of V15 III's and IV's, in
different turntables. I also experimented with using a V15 stylus assembly
in a M91 cartridge body, which required trimming a little plastic.

As others have noted, the trick is to adjust the capacitive load for
flattest possible response with the test record of your choice. You can also
do it by ear, if you have an educated ear.

I built a preamp that had variable capacitors on the input to facilitate
this adjustment. A number of commercial preamps, including Holman's APT
preamp also had this feature.

The usual subjective impression is that V15 cartridges are dull sounding
without proper capacitive loading. This effect may have been somewhat
reduced in later versions, but it was very strong in the II.

** Quite the REVERSE is true.

Shure V15s sound bright without additional C loading, beyond that found in
most RIAA stages.


This effect may have been somewhat reduced in later versions, but it was
very strong in the II.


** It was very noticeable with V15IIIs also

- to anyone with good hearing and speakers with good response to 20kHz.
