[HAM] Thanl you Kon-Taper resistances

[Kon Zissis]

Hi Bill.
I do not know if Hammond changed the tapering  after 1966. Most of the
measured TG output curves of the post 1966 organs that I have  look more
or less similar so therefore if there was a change it would most likely
have been  with the tapering  resistances.
 
 The only organs in my collection of measured TG output curves  that had
a very high treble calibration  were the H-100 series and the earlier
T-series organs and one late 60'/early 70's  UK built A100. 
The later T-series organs in my TG data collection have a TG curve more
like that of a normal B3 / C3 etc. 
 
I have played a 1970 T-300 organ with the very high treble calibration
and this sounded very thin and nasal. After I recalibrated the whole TG
to have a more normal B3 etc type TG curve , the sound was significantly
improved because it was now much fatter sounding. 
 
If a late era B3 sounds dull then it might be possible that the Tone
Control has been set to a low brightness setting , or perhaps the AO28
preamp or the Leslie have become dull sounding because of age related
deterioration.
All the best.

Then the complaints were it was too dull.  So Hammond put them back like
they were. Now I >don't believe this because I think they would be more
