Please read safety instructions before you use this amplifier!!!

Make sure you turn your amp off when you switch tubes and be careful the tubes might be very hot!! Do not touch tube sockets with fingers! Even after turning your amp off and unplugging it from the power outlet there could be enough voltage stored in the capacitors to give you a lethal electrical shock!

2. How to use it:

Read this owner manual completely before use to fully understand your Goldfinger’s functions. This manual is written for the 45 Karat Goldfinger. If you have the 90 Karat version keep on reading as almost all the functions are the same and then refer to i) for additional information.

a) Power, Standby and Half Power

1), 2), 48), 49)

To operate your Goldfinger hook up the power cable. If you have a head version you need to hook up a speaker cabinet, refer to j). Flip the big toggle switch located all the way on the left of the front panel from off to on. Give it a minute or two for the tubes to reach operating temperature. Your Goldfinger has a Hi (howdy) high as well as a Low power mode, flip the toggle next to the power switch from Stand By to either position. Hi gives you the full power available while Low gives you approximately 1/3 less. Remember it is not always necessarily about volume, it is a different feel as well. In Hi the amp has more punch with a tighter feel and the most available clean headroom. Low gives the amp a sagging loose feel, much like a tube rectifier.

On the back panel is a Half Power switch to disengage two of the power tubes.
