[HAM] New Hammond Factory Sound / Recapping etc. PART 2 - A One more attempt to post this

[Kon Zissis]

Hi everyone.
Again my last attempt to post the Part 2-A of my post was unsuccessful
because only the quotes from Ian Hooper and Paul Peters appeared but my
own text did not appear. I suspect that it has  something to do with the
fact that I had forwarded it from the original post whilst deleting the
parts 1 , parts 2B and parts 3 but the  grey bar on the right side of
the Microsoft Outlook page was still very small thus giving the false
impression that this is a very large post so perhaps the Hammond zeni
server automatically deleted the text because  it interpreted the post
to be too large even though the text is in fact a lot less than what it
originally was and the rest of the space was blank.
 Now for the last time I am sending the Part 2 A of my post but this
time I have copied and pasted it on to a new email page on Microsoft
Outlook. Let's see if this works .--Kon

The ESR is another factor to consider but I am not sure how this
actually affects the output levels of the TG notes . From what I have
read , the wax caps had higher ESR than the modern capacitors  so
therefore it would  be very interesting to compare the output levels
readings if a brand new wax cap with high ESR and a new modern
capacitor with low ESR but that both capacitors have an EXACT identical
mfd value  were tested on  TG note filters throughout the  various
frequencies in the TG notes 49 to 91 range.
 
Has anyone done this or can anyone explain how the ESR factor affects
the output levels or the resonance factor of the filter ?
