Somehow Accuphase does not rub the inscriptions from transistors ;-)))The new PA5 is packed with topping research results.
This is to prevent it from being easily copied. Such measures are natural for a company.
I know this because I made the E-550 clone myself.
a capable colleague cloned it only from the photos of the plate in the brochure. He was only wrong about one resistor value.
then we improved it as we got the schematics
