Product Description
Beautiful Dynaco 6V6 ultra-linear push-pull-up bile machine PCB board stereo.
NOTE:schematic for reference only,no schematic or components list provided.
The famous American sound Dynaco (Strong Bao) bile machine is famous, playing bile mobile hand faction has no unknown.
Dynaco 6V6 ultralinear line, 6SL7 (6N9P) tube 2 only zoom in reverse push-pull output, push 4 6V6 tubes, 4 6V6 tube design on the board for easy installation. Dynaco 6V6 circuit classic, cleverly designed. By the 6SL7 (6N9P) tube double function, both voltage amplification and automatic balanced inverted phase, and 1K resistance is the finishing touch, this resistance is the 6SL7 cathode bias resistance, and the output transformer secondary constitutes the reverse phase stage tail, but also loop negative resistance!
One-in-three jobs saves parts and reduces the additional noise and distortion of parts.
And the power stage using ultra-linear (UL) structure, taking into account the balance of efficiency and distortion, after a few modifications, the output power can reach 10W THD - 0.4%, damping is greater than 4.0, so simple line has such an indicator is indeed superior! Power supply is even more saving, just with CRC filtering, the whole machine S/N can be up to -107db A weight (absolute residual noise voltage 160uV) so low underground noise is basically the ear tight ennuth horn can stop to a little noise.
If the use of inductive filtering test has the effect of icing on the cake. Exquisite FR4 double-sided glass fiber plate gold plate, plate size 240 x 110mm, plate thickness 2mm. On the board marked resistance, capacitive parameters, good circuit performance, reasonable line, quiet line. As long as the wiring is correct, one-time success is the shortcut to success.
Also suitable for pushing 6P6P, 6P3P, 6CA7, KT66, EL34 and other electronic tubes. Component foot pitch, tube seat foot distance, foot hole size and other design is reasonable, suitable for the size of power resistance, capacitor.
The electronic tube seat is designed for dual use, and the resisting element can be welded on both sides.
The tube seat is a round foot hole and flat foot hole design, flat foot hole than the round foot hole is easy to weld not leak tin, applicable to a variety of electronic tube DIY line use.
Equipped with gold-plated tube holder, 25W aluminum shell cathode resistance, Japanese ruby electrolysis, Flying Pu electrolysis, German WIMA Weima capacitive cross-linking, precision five-ring resistance, Japanese chemical or ELNA tonic electrolysis and other components. Barrier element double-sided characters, can be two-sided assembly, tube can be exposed installation.
Note: The tube holder should be fitted with characters and cannot be refitted.
On-board port identification details, input, output, feedback, choke, power transformer, output transformer, cathode feedback wiring port, filament and other label details, assembly wiring is simple and not complex.
Line board can be used for KT66 power tube, the board of 2 250 euro 25W aluminum shell resistance can be replaced with 180 euros, welding machine please pay attention. Affirm: the components on the finished board are different due to assembly batches, some components used in the type, brand, model, specifications will be slightly different, to receive the assembly of components on the board, parameters will prevail!
Some components on the circuit board are second-hand disassembling products, finished plate detection is normal lying for sale. Dynaco Dynaco was born in the late 1950s in the United States, an established audio manufacturer, the first to start with electronic tube equipment and the world famous. In its heyday, Dynaco introduced the SCA35 Front, Stereo30 and Stereo70, which served as the design basis for a range of products since Dynaco. After 1966, transistors became a trendy gadget, and Dynaco had to launch the SCA80 and Stereo120 backstage to cater to the market, but it became the main cause of the company's insatiableness. After that Dynaco changed hands a few times, but the traditional style of the rich "bold" sound has not changed. Today's Dynaco products, despite modern production techniques, still adhere to their traditional line design. In addition, they adhere to the real and not expensive civilian route, the cost as far as possible to the internal design, not in appearance of waste. The black chassis, though insignificant, is a simple and well-sounding product in the eyes of pedestrians.
