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

[Kon Zissis]

Hi Scott and everyone.
I am still at the stage where I do quite like tinkering with the organ
out of curiosity and as a learning experience.
At the moment I am experimenting with getting a deeper fatter sound out
of the AO28 preamp by changing the feedback capacitors and resistors
that are wired across the input and the output of the two 6AU6 input
valves.  I am getting some good sounding results here so when I decide
on the best sounding combination of components I will then put in a
switch that selects the between the stock sound and the modified fatter
sound.
All the best.

Half of what I did was ultimately pointless, but there's much to be 
learned by fooling around with it.
