MM and MC phono preamplifier, with class A FET stage for MC.
TRX-EQ7: the design
The TRX-EQ7 connects a turntable to an amplifier that has no phono input, or adds MC cartridges to a phono input that only takes MM.
Compared with the TRX-EQ6 it has about 10 dB more gain. To keep noise down the power supply is external, in an adaptor separate from the chassis.
