The ST 410 boasts a solid, no-nonsense aesthetic that harkens back to the golden age of hi-fi. Its rugged black chassis, accented by a minimalist front panel with just a power switch and LED indicator, exudes a vintage charm. The build quality is impressive, with a heavy-duty construction that ensures longevity and stability. When it comes to sound, the Dynaco ST 410 delivers in spades. It offers a powerful 200 watts per channel into 8 ohms, providing ample headroom for dynamic and detailed playback. Whether you're listening to delicate acoustic tracks or thunderous rock anthems, this amplifier handles it all with ease. The ST 410 is known for its warm, rich sound signature, characteristic of classic Dynaco designs. The bass is tight and controlled, the mids are lush and full, and the highs are smooth without being overly bright. This balance makes it a versatile choice for various music genres, ensuring an immersive listening experience. She may not be the prettiest girl at the dance, but she sure could be the most fun!

- Liner Notes
The Dynaco Stereo 410 is a basic 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, uncolored 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 aluminum 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.
- Packing
- Prepare to be impressed. We have arguably the best packing process around. We use our InstaPak machine and white open cell foam to build a custom enclosure for your piece that ensures that it's stable and secure. If it is particularly fragile or heavy, we typically opt for private courier delivery. Depending on where you are in the country, that may cost a bit extra.
- Shipping
- This piece ships to the contiguous United States for a flat rate of $100, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
