This is a great looking and fully functional PAS 2 preamplifier. The PAS 2 & PAS 3 are the same units other than the faceplate & knobs. This is not a 3X however. All tubes are strong testing older US 12AX7s. The 12X4 is an original Dynaco labeled tube. This unit is not factory wired but a well built kit version. All inputs tested and sounds great. Controls and switches were recently cleaned for static free operation. Power light indicator works. All knobs are original and have the usual patina to show it! Tubes will be removed and bubble wrapped for safe transit. Preamp will be fully insured when shipped as well.

This is one amazing sounding preamp. It has been carefully serviced to ensure longevity and safety. All original Dynaco labeled Telefunken 12AX7 tubes are present, and really painting the sound of this to be just decadent. This preamp is everything that tube audio enthusiasts speak praise of. It’s midrange is extraordinary, and everything emanates with ease and roundness that only a high-quality piece of tube gear, with the right tubes can create. It is a very clean unit, with some minimal cosmetic flaws, including some minor lettering loss as you can see in the photos, as well as a scratch or ding on the face plate. Electronically, and functions 100%, with one minor quirk that has been a well-documented quirk of these PAS preamps. There is a slight imbalance in volume in the midway point of the volume control, but it is easily compensated,for by adjusting the balance control, which was as intended by Dynaco to keep things balanced throughout the listening range. You can connect two turntables to this preamp. The phono input will play as intended, and the “special” input has had the optional setting performed that will make it a phono input as well, so think of it as phono 1 and phono 2 A very involved service was performed as follows: First things first, the main filter cap has been completely rebuilt, re-stuffed with original values of high temperature electrolytics. Secondly, the filament power supply capacitors are were replaced with high temperature, long life electrolytics as well and the selenium rectifier was replaced with reliable diodes. Other standard services provided were testing each tube to ensure that it is strong and balanced, the controls were cleaned and lubricated, but the most important thing was fixing any previous errors in routing and wrapping wires to the re-create, the exact demands of the assembly manual. This is an important step to ensure quiet operation and minimal bleedthrough of sources.
