Offered for parts or restoration is this Dynaco Mono Block Tube Amplifier. I have no way to test this amp so i am selling it as is as found. This amp is very heavy but i have the box and styrofoam block to pack it for a safe delivery. Also local pick up is fine.

This is a vintage Dynaco MK III Output Transformer with model number A430-500. This is for a Dynaco MK III amplifier but has an added 500 ohm output tap. The ground, 4, 8, and 16 ohm taps are all there so it can be used as a usual MK 3 output transformer. The transformer has been used previously but is in good working condition. It is an essential component for anyone looking to restore or repair their vintage Dynaco amplifier. Get this reliable component today to enhance the performance of your vintage audio system.

Dynaco Output Transformers A-430 PAIR. These were used by Jim Fosgate for custom builds on his personal amplifiers. They are tested and working! Check out my other listings for more items from the Jim Fosgate Museum collection!

DYNACO ST 400 220v export model tres rare Magnifique IMPOSANT amplificateur de puissance 200W par canal 8 ohm état esthétique CUSTOMIZED black matt Cet appareil a été révisé COMPLETEMENT Tout les condensateurs transistors diodes resistances ont été remplace double interrupteur on/off - avec ventilateur- ou sans carte driver + alimentation pour vumètres indépendants 12vle châssis et le transformateur ont été entièrement repeints à neuf green leds vu meters magnifique sound DescriptionThe Dynaco Stereo 400 is a basic power amplifier employing all silicon solid state devices. They include 46 transistors, 47 diodes, 2 silicon controlled rectifiers, and 4 integrated circuits.The series-connected output circuitry is of full complementary symmetry design. The entire main amplifier is direct coupled. Its measured distortion levels approach the threshold of the most exacting 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 it contributes in large measure to the Stereo 400s freedom from listening fatigue.Its lucid, utterly uncoloured neutrality reveals delicate nuances and musical shadings in the best program material - one result of achieving unconditional stability with varying loudspeaker loads.Implicit in the design of a superb high power amplifier is the responsibility to include superior techniques of protection for both the amplifier and the speaker load, if long-term trouble free operation is to be achieved. To this end, Dynaco has included more separate protective systems and features than have ever been employed in such a product.These include an AC line circuit breaker (rather than a fuse); four separate power supply fuses; electronic volt-amp limiting to ensure safe operation of the output transistors; independent high temperature cut-outs on each channel, which are mounted directly on the output transistors to assure maximum sensitivity; over 1000 square inches of radiating area for the mammoth heat sink; provision for accessory fan cooling with optimum efficiency; delayed turn-on to eliminate loudspeaker thumping; relay protection against DC signals at the output; load (speaker) protection fuses accessible on the front panel; input level controls to reduce sensitivity; input filters to control the bandwidth; and the exclusive Dynaguard adjustable dynamic power limiting circuit to protect the speaker load.The Stereo 400 was engineered to accommodate a wide range of specialized needs in studio, laboratory and industrial applications, as well as in the home. It has been designed as two independent 200 watt (at 8 ohms) amplifying channels with a common power supply having a high degree of inherent regulation.For special requirements, a technician can easily convert it to a monophonic 600 watt (at 8 ohms) output.Accessory provisions for mounting on a standard 19 inch rack, an alternative front panel which includes two output meters, a cooling fan, and an alternative power transformer for international AC line voltages are available at additional cost. SpecificationsPower output: 200 watts per channel into 8? (stereo), 600 watts into 8? (mono)Frequency response: 20Hz to 20kHzTotal harmonic distortion: 0.25%Damping factor: 30Input sensitivity: 1.6VSignal to noise ratio: 95dBSpeaker load impedance: 4? to 16?Semiconductors: 46 x transistors, 47 x diodes, 2 x silicon controlled rectifiers, 4 x ICDimensions: 17 x 14 x 7 inchesWeight: 52lbs Compte tenu du poids de 30 kg sans emballage il est préférable de me demander le prix denvoi pour votre pays (avant de placer une enchère)pour une éventuelle assurance supplémentaire
