At first, it's no more than a sea gull swooping down and pecking at Melanie's head. Things take a truly ugly turn when hundreds of birds converge on a children's party. There is never an explanation as to why the birds have run amok, but once the onslaught begins, there's virtually no letup. ![]() Dynaco - Wikipedia. Founded by David Hafler and Ed Laurent in Philadelphia, Pennsylvania in 1. Dynaco was an American hi- fi audio system manufacturer popular in the 1. St in Philadelphia. ![]() Richard Crenna, Actor: The Real McCoys. Richard Donald Crenna was born in Los Angeles, California, into a modest-income family, the only child of Edith J. II 5. 0- watt power amplifier. II was sold for several years until its replacement in 1. Mk. III amplifier, which produced 6. Introduced in 1. 95.
ST 7. 0 was available as a kit (Dynakit) intended for assembly by the purchaser or as a complete factory- wired unit. The ST 7. 0 used four EL3. GZ3. 4/5. AR4 rectifier tube, two 7. PCB) containing the driver circuit. It produced 3. 5 watts per channel (wpc). The driver circuit had a single 7. The output transformers are an ultralinear design, whereby part of the primary winding is fed back to the output tube's screen grid. This design reduced distortion and improved audio quality. A masterpiece of efficient circuit design, the ST 7. The popularity of the ST 7. Because of its excellent value for cost, Dynaco tube amplifiers were often referred to as . In 1. 99. 2, an updated version of the Stereo 7. Stereo 7. 0 II, was produced by Sound Valves for Panor Corporation. Even today, upgraded components, rebuilding kits, and complete tube amplifiers using the basic Stereo 7. ST 7. 0 has inspired numerous other amplifier designs, such as Ars- Sonum's Filarmonia SE. Dynaco continued to build both mono and stereo amplifiers until 1. The company's final contribution to vacuum tube technology was the massive Mk. VI mono power amplifier of 1. In later years, the company began to produce a line of solid- state audio components, commencing in 1. Stereo 1. 20 power amplifier (6. Because of early problems involving circuit, power supply, and transistor failures, the ST 1. Dynaco tube amplifiers. Numerous small circuit changes were introduced by Dynaco over the years in an attempt to improve the stability and reliability of the ST 1. With the PAT- 4 preamplifier in 1. In the 1. 97. 0s, the Stereo 4. This was a high power amplifier at 2. The FM- 5 tuner was offered as was the SCA- 8. There was also the Dynaquad system which allowed the user to simulate a quadrophonic sound by using out of phase signals at the speaker terminals. It apparently was a success and offered good four- channel sound at budget price. Dynaco's solid- state kits were different from the popular Heathkit products (and Dynaco's own vacuum tube kits) because of their preassembled circuit boards. These boards were wired at the factory, tested and packaged with the unassembled chassis. It remained only for the consumer to attach the switches and controls to the chassis pieces, assemble the chassis and power supply, and solder connecting wires to the circuit boards. This saved considerable time and reduced error in assembly. Dynaco also distributed the famous SEAS 'A- Series' of bookshelf loudspeakers that were manufactured in Denmark, using input from Dynaco's David Hafler and SEAS' Ragnar Lian. The A- Series were marketed between from 1. Dynaco's demise in the 1. The Dynaco A- 2. 5 model proved to be extremely successful, selling between 6. The patented aperiodic (essentially non- resonant) woofer design utilized a highly damped vent instead of a reflex port, whose acoustic resistance is very carefully controlled. The resistant venting action lowered the . Dynaco followed the A- 2. A- 3. 5, which featured a dual- chambered, non- vented design in a walnut- veneered cabinet with even greater transparency and fidelity. Over time, Dynaco marketed a wide range of loudspeakers, ranging from the small A- 1. A- 5. 0 series. After some 3. Bay, and are a testimonial to their quality. Concurrent with A- 2. Dynaco introduced a speaker system whereby 4- channel sound could be easily derived from stereo material by using a rear channel speaker matrix. The system worked best when the stereo sound had been recorded via two bidirectional microphones on the same spot. When microphone set- up changed to the use of multiple directional microphones and multitrack tape recording and postprocessing (i. David Hafler remained with the company a few years longer, but left in 1. Ortofon, manufacturer and importer of high- end phono cartridges. In 1. 97. 7, Hafler founded the Hafler Company, continuing the tradition of high quality but inexpensive kits and assembled hi- fi gear. In the late 1. 97. Dynaco released a short- lived set of new loudspeakers developed by Ed Laurent, the Phase III. The speakers were well regarded by the audiophile community, but their introduction was apparently too late to make any strong impression in the marketplace, and Ed Laurent left shortly afterward to join SEAS Corporation. After Dynaco closed its USA operations, its former Canadian subsidiary released the Dynaco A- 1. A- 2. 50, and A- 3. Canton, Massachusetts. Panor introduced some new products and reintroduced the Stereo 7. Stereo 7. 0 II. Panor/Dynaco's most ambitious stereo tube amplifier was the Stereo 1. While Panor owns the Dynaco brand name and trademark, there is no longer any direct connection with the company founded by David Hafler.
