ASCO EV24 or EV34
                   
    Tube Classics Röhrenendstufe Röhrenverstärker amp Asco EV24 EV34 EV 24 34  

  ASCO means: "Arthur Steidinger and CO." He was one of the many Steidinger brothers who gave us DUAL and Perpetuum Ebner.

  ASCO units are much rarer than the other and they are the BEST of those from the "Black Forest brands" !!! They also made amplifier units for other brands and for professionel equipment.

 

  This power amp (called EV24 for delivering 12 watts sine wave or EV34 for 17 watts music power per channel) is the best German EL84 stereo power amp (section) ever made. The output transformers use:

 - 8 interleaved windings

 - cut cores

 - ultralinear connections

  The result is an impressing frequency response from 20-100.000Hz (and higher) and very, very beautiful sound.

Cut Core OPTs

             
                   
     

  Inside: No printed circuit boards, in my unit some caps were replaced for new ones.

  The upper speaker connectors are for 4-5 Ohms speakers loads, the lowers for 15 Ohms.

 
   

 

             
                   
     

  The circuit is simple (and close to Grundig NF2). The additional filament and B+ connections are used to supply the ASCO preamp SV24.
