Quad 34 preamplifier
This solid-state design is supplied with a built-in moving-magnet cartridge preamplifier, and a moving-coil preamp is included with it for (easy) installation by the user if desired. (Remove two screws, pull out the old module, plug in the new one and replace the screws. The job takes about 3 minutes.) The MC preamp supplied is for 20 microvolt-output cartridgescontrary to the instruction booklet's statement that the supplied one is the 100µV version. Modules having a rated input level of 100 or 400µV are available as extra-cost options.
