Audio amplifier with EL84 tube.
| WHAT CAN I USE AN OLD RADIO WRECK TO? I found an old Tandberg Sølvsuper 75 in the garbage. What can I use this for? The radio is from 1959, and was one of the first stereo amplifiers. |
Tandberg Sølvsuper 75
I build a stereo amplifier in an IKEA box of the parts from the
Tandberg radio.
Inside the amplifier. Tandberg output trafos and Tandbrg power
trafo.
Power supply
| Have my "own way" to make tube amplifiers.
Each stage has its own feedback. I use a form of feedback
that is not so common in older tube design. Have a
feedback via a resistor from the anode to the grid. Also
has a series resistance to the grid. These resistors
determine the gain in the stage. I do this to get good
sound. Have listened, and I like this sound. V1 = ECC83, V2 = EL84 The entire project took only a couple of hours to create. I tested on two large Paradigm speakers with good results. It sounds nice. |
