Main Features
Strong chassis structure of a 2 unit box with Lch and Rch being independent and completely monaural.
V-I / I-V conversion type all-stage symmetrical non-feedback amplifying circuit due to all discreet parts.
Three input terminals are equipped and MM/MC switching is possible for each. In addition, inputs 1 and 2 support balanced inputs due to the XLR connector.
A 2nd order CR type low cut filter with non-feedback is equipped. Plays warped phonograph records without any music deterioration and prevents the speakers (woofers) from shaking.
Three types of playing curve changeover switches are equipped. For the equalizer characteristics, along with the RIAA characteristics for the previous stereo, Mono1 (used on the DECCA label and so forth) and Mono2 (used on the Colombia label and so forth) are equipped as a particular characteristic for a monaural. This will allow higher fidelity playback than the DECCA and Columbia labels.
A “degaussed” circuit is equipped.
By choosing “degauss” with the functions and playing the record for about 30 seconds, the MC cartridge with a metal core that was magnetized is degaussed and the sound quality becomes clear.

First Watt F7 Power Amplifier
The F7 is a very unique power amplifier.
Aa two-stage push-pull JFET/MOSFET topology with fewer parts than any First Watt amplifier to date and incorporating a very interesting balance of very low negative voltage feedback and a little bit of positive current feedback to give an astonishing measure of control over reactive loudspeaker loads.
