[HAM] DC filtering to the heater filament voltage of the AO28

[Kon Zissis]

Hi Keith.
My modified Leslie 122 has an efficient  200 watt RMS rated  Lorantz
C386PA16  16 ohms bass speaker and  I can feed any external amplifiers
directly to the speaker jack . 
I can put my C3 through an external  graphic equalizer and then boost
the lower bass frequencies and then send this signal  to an external
amplifier whose output goes into the Leslie 122 speaker jack , and then
do another AB test with the    AC filament wiring and the filtered  DC
filament wiring.
All the best.
Kon

superior bass reproduction. The difference, if any, would be readily
apparent.
