Need manual for Golden Tube SI50 MkII

Would appreciate if any user or ex user share with me the manual (not schematic) of Golden Tube's Si-50 mkII.
Need instructions for bias pot accessible from top of unit.
Too lazy to trace it. Thanks.

Anyone still watch this? I have several friends with this amp. After a few years, some of the LEDs stop responding to the bias pots. At that point you have no idea what's going on. Even if one or two still work it's the same problem. Anyone have an idea for a workaround?
