In the German magazine Funkschau Number 8 from the year 1974 you will find a detailled circuit description from page 251 to 254 about this model.īTW the term ELA is the German abbreviation for "Public Address" (PA)Īnd stands for E lektro akustik (electro acoustic)īut in New High German colloquial usage this terms no longer the same Įla means that the application was improved for voice transmissions without music, i. I like such designs, because it is easy to get a symmetric signal behaviour.Ībout the Telefunken model (ELA power amp) "V665" with 250W output power no pics and information online at this time (auctions from ebay unfortunately always deleted after 3 months). Here some URLs from this model and related other models probably with similar schematic:Ģ x DYNACORD DEM 286 Verstärker ENDSTUFE 200 WATT bei : PA-Verstärker Endstufen (endet 02.06.10 12:29:30 MESZ)īasicly great similarity with the topology ofĪfter certainly modifications (especially after remove the frequency low/high pass limitations) this could be a ultimate sounded home hifi power amp. The circuit description is to find in the German Magazine "Funkschau" number 3 from the year 1984.

The detailled circuit you will get from Dynacord as PDF file. Instead the six emitter resistors there are six primary windings of a big fat output transformer "DCN 330775". This one drive a push pull darlington pair that consists of one 2N6487 and three parallel switched 40636 from RCA for each half (40636 = 2N3055 with higher value for Vceo). The heart of the circuit is a TDA 2616 IC which is a stereo amplifier IC comes in 9 leads and SOT131 package A very simple two transistor amp circuit which can be use in any place where a little amplification of audio is required.
2N3055 TRANSISTOR STEREO AMPLIFIER CIRCUIT DRIVER
The Dynacord amplifier without global NFB and driver transformer and output transformer works with 2x TDA2030 for driving a very fat driver transformer "DCN 309272".

THIS MODULE CARD CAN BE USED TO PROVIDE THE AUDIO SIGNALS TO THE BOARD. Complementary Silicon Power Transistors.this transistor is 15-ampere power transistors supplementary silicon 60 volts, 115 watts. here used PNP and NPN transistor 2n3055 and mj2955. THE TRANSISTORS ARE INSTALLED ON A SILICON SEPARATE WHICH PREVENTS THE TRANSISTORS FROM SHORTING AND OTHER VOLTAGE DAMAGES.THE BLUETOOTH MODULE CARD THAT COMES WITH A REMOTE CONTROL. This is a 2n3055 amplifier circuit diagram 200 watts. THE HEATSINK IS MADE UP OF HEAVY GAUGE ALUMINIUM FOR EASY AND SMOOTH HEAT DISPERSION. THIS SET OF FOUR TRANSISTORS IS MOUNTED ON A HEAT SINK. ALL THE POTENTIOMETERS WILL BE SOLDERED IN, EXACTLY LIKE THE IMAGE SHOWS. THIS BOARD WILL BE PROVIDED AS SHOWN IN THE IMAGE. YOU CAN PLAY MUSIC STREGHT FROM THE BOARD.THE MAIN BOARD HAS THE CONTROLLING CONNECTIONS OF VOLUME, BASS, TREBLE BALANCE ETC. THIS MEANS YOU JUST NEED TO CONNECT A 24-0-24V AC 5 AMPERE ABOVE TRANSFORMER TO THE BOARD AND YOU ARE DONE. THE BEST PART ABOUT THIS KIT IS THAT ALL THE POWER SUPPLY COMPONENTS ARE BUILT IN ON THE BOARD. THE MAIN BOARD CONTAINS ALL THE NECESSARY AMPLIFIER COMPONENTS. Simply by incorporating just four transistors in the quasi-complementary configuration this 2N3055 simple power amplifier circuit can deliver a good 100. BOTH THE CHANNELS PROVIDE ABOUT 175 WATTS AT FOR 4 OHMS SPEAKERS. THESE CONTROLS ARE OPERATED BY THREE POTENTIOMETERS, ALSO KNOWN AS TONES. THIS BOARD HAS SEPARATE CONTROLS FOR BASS, TREBLE AND VOLUME. THIS BOARD USES FOUR 2n3055 TRANSISTORS AND A 24 VOLTS AC POWER SUPPLY TO GENERATE AN OUTPUT OF ABOUT 300 WATTS. THIS IS AN AUDIO AMPLIFIER CIRCUIT BOARD BASED ON 2n3055 TRANSISTORS.
