First Watt F1J For Lowthers, Etc. [Expired]


no longer for sale

I have a First Watt F1J in excellent condition with factory packing. The F1(J) is a current-source amp with *no feedback* (of any kind) and *one gain stage*. It is about the purest, simplest form of amplification possible, and perfect for driving any sort of wideband driver (see Nelson Pass's excellent white paper on current-source amplification). This is the F1J model, updated with JFets, which Nelson says measures - and sounds - "about three times better." 10W. Other specs on the First Watt site. Manual online.
