Dynaco PAS 2/3 和 PAS-3x 之間的區別
There are two basic circuit differences between the earlier Dynaco PAS-2 and PAS-3 units and the later PAS-3X preamp.
1) The "X" version had tone control potentiometers that were constructed to be electrically removed from the circuit when set to their flat position.
2) A 1uF electrolytic capacitor was placed in each channel’s tone control circuit to block the DC from reaching the audio output.
