Cayin TA30 Tube Amp - Info Needed

Looking for manual/documentation for the Cayin TA30 Tube Amplifier. I bought one last year from a friend, gently used but have no documentation on it. I need to know which way i need to have the two switches facing for it to be in pentode mode, and NOT triode mode. Facing inwards or outwards? Anyone who may know or direct me to some documentation please let me know!

This one has the bizzy bee mods from Paul, but i believe these switches are stock. Thanks.
