Valve line stage preamplifier
JPL The sober and elegant JPL monoblock preamplifier, its protective grill and the height of the face plate masking its component parts, never fails to arouse our curiosity through its discreet appearance.
This preamplifier is made up of three 12AX7 double triodes. The gain ,
of about 35 dB, is supplied by the first two tubes mounted in series.
The last tube is used as a cathode follower, which allows the use of a
long cable without the disadvantage of a drop in the treble.
The quality of the JPL comes from a highly selective and careful choice
of passive components, and of the extremely precise manual production
of our circuits.
