Seller\'s Introduction:

I have for sale a Classic Dynaco 400 Audio Power Amplifier with the Blue Analogue Audio Power Output Meters.

Cosmetically the amplifier is in nice condition, please see pictures, with some imperfections.

Functionally, the amplifier powers up, but no sound comes from it when attempting to play source material.

The Dynaco 400 is one of the best known, classic transistor amplifiers in \"Audiodom,\" and there are many places and individuals who work on it and offer mods. Information regarding it abounds on the Internet; the information I have included below in this add is from the Internet.

As I said, this classic amplifier is well known in \"Audiodom.\" Therefore, doing a search on DYNACO 400 on the Internet will turn up all kinds of results.

NOTE: Because this amplifier is not functioning, it is being sold \"AS IS FOR PARTS AND/OR REPAIR.\"

DESCRIPTION FROM THE INTERNET:

The Dynaco Stereo 400 is a basic two channel 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 contributes to the Stereo 400\'s freedom from listening fatigue. Its lucid, utterly uncolored 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 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 cutouts 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.

Comments:

Dynaco\'s blockbuster 200 watt per channel amplifier, continuing the tradition of value for price and enthusiastic reviewer response. Featured Dynaguard™ speaker protection circuitry, sophisticated automatic output muting, and a colossal heat sink. The FAN-1 option further improved heat dissipation for PA and sound reinforcement applications. The MC-4 option added accurate power output meters and a range switch. The MBI-400 bridge kit allowed use as a single channel 600 watt amplifier.

As I said before, these import cost vary from country, but almost all countries will impose some kind of duty and/or tax to import an item from outside its boarders. Please, also do not email the seller to ask what these import cost might be: I ship the item myself, and can not tell you for each and every country. Though has a program where the buyer pays these cost upfront, the overall cost to the buyer is likely to be more expensive if shipped that way rather then the buyer paying for the shipping cost and whatever duties and/or taxes they must pay once they receive the item at their location.
