This preamp was built around the mid / end of the 70's to the beginning of the 80's. It is the only preamplifier Infinity ever built. Only 200 of this preamp were built! The F.E.T. Preamp was not produced for the European market and therefore it should not be available in Europe, especially since this device was built exclusively for 117 V/AC (not switchable to other values). However, exceptions prove the rule, because 1 copy does exist in Europe.
The F.E.T. Preamp is a preamp suitable for the Swamp power amp. The F.E.T. Preamp was built at about the same time and in the same design as the Swamp. These two devices complemented each other.
Technical Data:
- Frequency range: line 20 Hz - 100kHz +/- 1dB and 1 Hz - 230 kHz -3 dB, phono 3 Hz - 50 kHz -3 dB (MC).
