Vintage Tube Amp

The Dynaco Stereo 410 is a two channel power amplifier employing all silicon semiconductors. They include 38 transistors, 2 zener diodes, 24 diodes, and 3 thermal sensors. The output circuitry is of the full complementary symmetry design. The entire amplifier, except for an input network, is direct coupled. It’s measured distortion levels approach the threshold of much laboratory test equipment, not only at the commonly specified full power ratings, but more importantly at very low power outputs as well. This is the result of circuit techniques which eliminate any discernible crossover notch at low levels, and contributes to the Stereo 410′s freedom from listening fatigue. It’s accurate, uncoloured sonics have been achieved on a wide variety of loudspeaker loads, including electrostatics and multiple drivers with complex crossovers. The design of a superb power amplifier implies the necessity of several protection techniques for the amplifier, and for the speaker load. In addition to the AC line fuse, four separate B+ fuses are supplied. Electronic volt-amp limiting ensure safe operation of the output transistors, and an independent thermal cut-out for each output stage protects from high temperature. A large radiating area for the heat fins, which are attached to an aluminium back panel, and cooled with a thermostatically operated two speed fan, form a highly efficient heat sink. Speaker fuses protect the load. The Stereo 410 has been designed as two independent 200 watts (into 8 ohms) amplifying channels with a common power supply having a high degree of inherent regulation. In addition, where higher power is required, an extra cost circuit board assembly will be made available to permit monophonic (bridge) operation for 8 and 16 ohm loads. An accessory kit is also planned at additional cost for two output meters and meter switching, which includes an alternative front panel. Power output: 200 watts per channel into 8? Frequency response: 20Hz to 20kHz. Total harmonic distortion: 0.25%. Input sensitivity: 1.6V. Signal to noise ratio: 95dB. Speaker load impedance: 4? Semiconductors: 38 x transistors, 2 x zener diodes, 24 x diodes, 3 x thermal sensors. Dimensions: 17 x 14.5 x 7.25 inches.
