So sorry, but what FOSI says in the amp's description: Quad Tubes: Features two 5654W and two 6Ж4/6Ж8 vacuum tubes for two-stage amplification. The 5654W tubes boost voltage, while the 6Ж4/6Ж8 tubes handle power amplification. This setup delivers balanced, transparent, and textured sound So...

Loads of thanks for Your review, Patrick! It would be very interesting to view the circuit diagram of this amp to understand in what mode works 5654W tubes. I think it's a triode mode, hence it also will nice work with 9002 and 9003 tubes from GE. Of course if back side board image would be a...
