Works perfect!

Core Design & Operation

  • Dual Power Topology: Combines Class A and Class AB in the same power block.
  • Tube Pairing: Uses four power tubes total in mono sections (or sets of 4 per channel in stereo units). Inner tubes handle Class AB; outer tubes handle Class A.
  • Switchability: Allows scaling down from full high-wattage Simul-Class operation to lower-wattage pure Class A operation. [1, 2, 3, 4]
