Built to order, made just for you.

THIS IS A "SPECIAL ORDER". This PAS-3  (also called PAS-M) Tube Preamplifier requires a 3-4 week production period. Each unit is custom built. I need time to order the components and of course time for assembling and testing the unit. Often there will be a few orders to complete before I get to your build. The component varieties, brands and features offered are proven top performers. You can buy with confidence, I'll build you a great sounding preamp. If you need one now, please check to see if one is "ready-to-ship".

The photos shown are of previous units, with upgrades, to provide visual examples. Generally speaking, most units look very similar when completed.

The aluminum faceplate has updated (modern) nomenclature printed on around the selector knob, it matches the selectors functions and also the rear panel orientation and label. Again, the indicated selector functions match the rear panel labeling and follow the designated order on both the faceplate and the rear panel label. There are no provisions for a filter, loudness or tape monitor switch, so those functions are eliminated. The stereo to mono blend switch is also omitted, and the volume control is relocated above the balance knob as shown in the photo. The rear panel has jacks for 5 line level (high level) inputs and one phono input and there's a phono ground post. 

NOTE: Due to limitations of the selector switch, there are no tape loop or tape monitor functions. You will not be able to use this preamp for recording. This preamp is designed for playback only. It is suggested to have only one source at a time playing to reduce the potential for crosstalk.
