Line Block Preamplifier
P.O.A.
The Line Blocks are mono line-level preamps two of them for stereo. You can carry the advantages of true dual mono construction all thru every element of your system (that is, everything but the cartridge!).
The Line Blocks preamplifier uses 1950s-style Nixie tubes whose elements display numbers depending on which elements (within the tubes) get voltage fed to them.
The two other Line Blocks’ chassis have all the input and output connections, and are where the signals are actually buffered and amplified, thereby keeping the control electronics well away from the audio signals in dual mono.
