Technics SE-9060

Small and big DC power amplifier, part of the "Professional" Series.

If Technics had a tendency to see pros everywhere, the same can be said of almost all brands between 1975 and 1980 : rack handles, stark dark looks à la Vador (sans breathing) and seriously serious literature !

As per Technics' 1960s and 1970s amplifier names in Japan, the SE-9060 really was an 60AII in Japan.

The 1977 "II" is there because the export 9060 was equivalent to the revised version of the late 1976 60A original : bigger trafos, better S/N and damping factor, less residual noise, the addition of a 2Hz filter switch (just in case), the possibility to bridge the two channels to make a monoblock and... more output power.

At 100,000¥, a 60II wasn't really high-end by japanese standards but quite close enough. The SE-9060 (60AII), shown here, has :

• All DC circuit

• differential amp with Current Mirror Load and dual-FETs in the first stage

• constant current load instead of conventional bootstrap in the voltage amp

• pure complementary SEPP with 3-stage Darlington circuit

• temp stabilized FETs for DC stability

• triple protection system : DC drift, over-current and over-heat detections

• stereo / mono operation with simple (back) switch and no rewiring necessary

• dual power supplies with four 18,000µF capacitors and two trafos with triple magnetic shielding

• relay switching for the speakers' selectors and 2U EIA standard dimensions.

The SE-9060 embodies the traditional 1977 "professional" amplifier version of Sony's futuristic but equally "professional" TA-N86B : heavyweight power trafos in Class B vs. Pulse Power Supply and pure Class A.

Although the former isn't rare at all, Sony sold more N86Bs than Technics did sell 60A and 60AIIs...
