Need manual for Golden Tube SI50 MkII

Hi,
I have the amp and manual.
If you still need the manual let me know and I will scan it and send it to you.

Here is a summary of the procedure: First let the amp warm up for at least 15 minutes. (With no music playing) Press the mute button until the power LED flashes orange. (2 to 3 seconds) Using the pots on top of the unit, adjust until the LED's are lit for each tube (Pot 1-mute led, pot 2-input 1, pot 3-input 2, pot 4-input 3). The LED's will be solid or blinking. Blinking means a week tube but it's still ok for operation. The biasing interacts so you might need to adjust all the pots several times. Also, when the adjustment is way out you will hear noise from the speakers.
When you are done press the mute button until the LED's return to normal. ( 2 to 3 seconds )

Regards,
Steve

Thanks a lot SD58.

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?
