Hello everyone,
I have for sale pair of DIY finished boards of B&K st 140 amplifier built on the original exactly schematics.
Construction with components of absolute audio quality and definitely superior to the original:
  • Nichicon Fine Gold audio capacitors
  • Nichicon MUSE audio on the signal path (green)
  • MKP bypass capacitors (Polypropylene)
  • Cornell Dubilier silver mica capacitors
  • ORIGINAL HITACHI K135 and J50 final MOSFETS
  • Construction with Cardas tin.
Calibration as service manual 200ma @ 20kHz and zero DC offset (see photo) and absolutely perfect measurements in terms of bias, DC offset and THD (see measurements).
Power supply required dual 60V DC to have the nominal power of 105Watt/channel on 8 ohms.
Sound very well and powerful with NO hum and perfectly stable in temperature and elecrtical parameters.
Big heat sinks is not included.
Price request 80 Euro plus shipping (From ITALY).
Consider that the Hitachi mosfets alone are worth the asking price.
