Dynaco made this preamp in several versions with many parts variations within each version. Many sellers do not know how to distinguish PAS 2, 3 from PAS 3X. The 3X is later most desirable version. The distinguishing factor that separates the versions is that PAS-3X has tone control bypass caps from tone controls to pc board. These null the controls at center position. There is almost no labeling difference on the preamp or serial number. The serial number and designation is only on the manual which is often lost or separated from the preamp. But there are some physical differences between the versions.PAS 2 and 3 have: Typically push on tone control knobs which have 270 rotation. No tone control bypass caps. Typically power supply caps are Red or orange (early version) or Green later version).PAS 2 often has label on rear stating PAS 2. PAS 2 has brass face and plastic brown knobs. Aluminum face and metal knobs was an optional upgrade. PAS 3 has aluminum face standard.PAS-3X has: Often has set screws on tone control knobs as well as separation and balance. Typically tone control knobs are short 180 rotation. (different pots than PAS 3). Always has Bypass caps on tone controls to board for center null. Typically Silver or blue power supply caps. Aluminum face standard.
