| − | '''Special Features'''
| |
| − | * Rugged chassis, so-called Gibraltar construction, reduces distortion possible due to vibration.
| |
| − | * Large-dimensioned, coiled toroidal transformer always provides sufficient power even for the highest dynamic peaks.
| |
| − | Preamplifier section: Low-noise, high-gain NFB equalizer amplifier.
| |
| − | Power amplifier section: Purely complementary push-pull stage.
| |
| − | * Tone control section with exclusively passive components to avoid distortion.
| |
| − | * Power amplifier in super legato linear system ensures high output power.
| |
| − | * With simultaneous A & B speaker operation 8 - 16 ohms, otherwise 4 - 16 ohms.
| |
| − | * Direct input for undistorted reproduction of the signal sound source
| |

| − | | |
| − | == Remarks ==
| |
| − | * Other models of the same series:
| |
| − | | |
| − | * The F670 is nothing more than a pimped version of the F570. So the filter capacitance of both the output stages and the power amp front ends was doubled and additional smoothing inductors were added there. The foil-C in the filter network of the phono preamp now have 100V instead of 50V etc.. The audio electronics, as well as the platinum set is the same. The additionally offered preamp output is a fake and nothing more than a down-amped power amp output, like the headphone output. Whether that is worth the meanwhile quite large price difference of both models in the second-hand market, everyone must decide for themselves.
