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.

David Hafler and Ed Laurent founded the Dyna Company (later Dynaco) with the intention of not only producing transformers, but high-quality audio circuitry. The company was incorporated in October 1955, with business premises located at 617 N. 41st St in Philadelphia. Dynacos first product was the Mk. II 50-watt power amplifier. Available as a kit or pre assembled unit, the Mk. III amplifier, which produced 60 watts. Dynaco continued to build both mono and stereo amplifiers until 1977. The companys final contribution to vacuum tube technology was the massive Mk. VI mono power amplifier of 1976, which produced 120 watts (continuous). Dynaco is best remembered for its highly regarded vacuum tube stereo amplifier, the Stereo 70 (ST-70). Introduced in 1959, the ST-70 was available as a kit (Dynakit) intended for assembly by the purchaser or as a complete factory-wired unit (Dynaco). The ST-70 used four EL34 output tubes, one GZ34/5AR4 rectifier tube, two 7199 input (driver) tubes, two output transformers, one power transformer, and a pre-assembled printed circuit board (PCB) containing the driver circuit. It produced 35 watts per channel. The driver circuit had a single 7199 pentode/triode tube per channel, and used the driver tube to handle both voltage amplification and phase splitting. The output transformers are an ultra linear design, whereby part of the primary winding is fed back to the output tubes screen grid. This design reduced distortion and improved audio quality. A masterpiece of efficient circuit design, the ST-70 provided reliable, high-quality audio amplification at an affordable price. The popularity of the ST-70 contributed more than any other single product to continuing consumer interest in tube-based stereo amplifiers at a time of increasing market dominance by solid state audio products. Because of its excellent value for cost, Dynaco tube amplifiers were often referred to as the poor mans McIntosh.
