Ultimate Threshold FET-10E Preamp - Extremely Rare Final Production Unit [Expired]


no longer for sale

Extremely rare and final production Threshold FET Ten E linestage in very good cosmetic and perfect working condition.   These special end super versions with hand selected and tightly matched parts.  This is the best product they could build incorporating all the lessons learned over years of production.   Cosmetically unique with knobs only found on these units.  According to Pass himself there were less than 20 made (no-one recorded the exact number).   

This unit was sent to Jon Soderberg at Vintage Amp Repair (former Threshold and recognized expert for all Threshold products) for a complete health check.  DC offset was adjusted and electrolytic capacitors were replaced in the power supply and main board for years of trouble free operation.   The unit is at Vintage Amp Repair and will ship from California.   You don't have to take my word about this unit - Jon is available to answer questions (916) 721-9611 [email protected]  

Collectible with a dedicated following to this day as witnessed by the Threshold Lover's Website. Per the description of the variants below, this is a E-T / Version 5 model.  Purchased from an audio friend who is also an electrical engineer that spent lots of time studying the variations and production changes as he bought and sold FET-10s.
