Elektor amps are always very experimental or draft designer's ideas. If you really want to use 2N3055s, you might want to try the Circlophone, extensively tested here by many.
Hello everyone, I am working on an old Elektor MPA amplifier board and I am looking for information about suitable replacement transistors for MAT02/MAT03. I already have some crash‑test transistors (BC550C/BC560C) and low‑melt alloy for safe desoldering. If anyone has experience with...
hello, the Elektor May 1970 issue is downloadable here : Verstärkermetamorphosen - ELEKTOR.de | Elektronik: Analog Digital Embedded Mikrocontroller Audio Messtechnik Have a look to the Elektor Edwin 20 watt schematic (attached .jpg). There is a small class A amplifier nested inside a pure...
Elektor diagrams and board patterns Last year I inherited a complete set of elektor magazines from the start (about 1970, german edition) and after looking through one can say that diagram style and board patterns changed from time to time. In the beginning they had the "minimum etching" style of circuit boards with plenty of copper, nicely curved, without separate solder "eyes" for components ...
Hello all, I am working on my DIY Preamplifier new project based on the Elektor Preamplifier 2012 (Douglas Self) schematic. I don't need the TONE and BALANCE control sections in my design, painted in Red in the picture below. I will directly connect the output of IC2A pin 1 into the input of...
Hi, I remember in the 1990s Elektor had published a schematic op a pre-amplifier that simulated the sound of vaccum tubes ie the same warm sound that tubes are famous for. Does anyone have that article/schematic and can please share? Thanks and Regards, WonderfulAudio
