Hi, this is my first post here. I recently acquired an incomplete amp and receiver to obtain spare parts for my Beomaster 2000. What's left of the chassis and the general form factor are matching the original Beomaster, but this incomplete amp is quite different when it comes to sliders and  switches. While the "normal" Beomaster 2000 has 4 sliders for:
  • Volume
  • Balance
  • Bass
  • Treble
The new incomplete one has:
  • Volume (2 sliders parallel)
  • Balance Front
  • Balance Rear
  • Balance Front-Rear (2 sliders)
  • Bass (2 sliders)
  • Treble (2 sliders)
There's also a "PHONO 4CH - 2CH" instead of the "TAPE 1 - 2" switch underneath the left sliding cover (which is missing the "Beomaster 2000" text and only saying "Loudness"). The source switches for "LW" and "MW" are replaced by "STEREO" and "MATRIX".
This is the print and label on the bottom of the unit:
