Such dedication! It would be interesting to hear how good this discrete version could
sound using the much faster and better LAPT Sanken chips likely used in the hybrids.

Great work!

The Sanken SP-40W hybrid does not use LAPT (High frequency multi emitter transistor) chips.

My immediate thought would be to build a replacement board using a pair of Sanken STD03 transistors, or even the Onsemi ThermalTrak series
