dallas rangemaster electronics advice...

[barret77]

Hello all

In the geofx dallas rangemaster building pdf PDF, it can be read:

"The Dallas Rangemaster has an output impedance no higher than the output
pot resistance of 10K, and lower than that over most of the pot travel. This is
substantially lower than the equivalent forward biased grid resistance of a
12AX7, so it can drive an input grid somewhat positive. The resulting
distortion is smoother than a high impedance source would be. Note that amps
that have series 68K resistors for “mixing” two inputs may not show the full
benefit of this effect."

Well, my amp has the 68k resistors, and a 1Meg one: http://www.guitar-parts.com/images/ga17rvt.jpg


What can I do to get the "full advantage" of the effect without tinkering the original circuit of my amp? And tinkering, is there a way to solve this?

thanks for any feedback!
