k) Foot Controller 5), 4), 33), 37)
To hook up the foot controller, align the XLR type plug properly with the foot controller’s connector and
then push the plug in until it snaps and you won’t be able to pull it out. To detach, press the release
button on the plug before pulling on it. The other connector on the cable plugs into the amplifiers Foot
Switch connector on the back panel. Align the plug properly then push it in; this plug has a barrel nut to
secure the connection, screw clockwise hand tight, do not over tighten!
Each of the 5 functions has a LED which correlates with a LED on the amplifier to tell you visually what is
engaged and what is not. Keep in mind, like mentioned before, the foot controller overrides the CH.
Select and Pre FX Boost switches on the amplifier. The Post FX loop must be switched to “on” on the
amplifier itself in order for the function to work via the foot controller.

Your 45W Goldfinger comes with JJ 6V6 while your 90W comes with JJ EL34 power tubes.
The Goldfinger has a set of bias adjust trim pots with the according test points. These are set by the
factory and should not be touched as they can make your power tubes run hot resulting to short out and
fail! If you need to retube the power amp have a knowledgeable Technician set the bias correctly.
With the exception of V4 all pre amp tubes are 12AX7/ECC83. V4 uses a JJ12AT7/ECC81.
While we use the JJ brand others work as well.
The Goldfinger has 5 pre amp tubes:
V1 12AX7 Tungsol - α+ Ω channel > check that one if your amp gets noisy or microphonic.
V2 ECC803S JJ Tesla - Ω channel > another candidate for microphonics.
V3 12AX7B Chinese - phase inverter
V4 ECC81 JJ Tesla - Post FX Loop, standard a 12AT7 or ECC81 type
V5 12AX7B Chinese - α + Ω channel
- Tube selection subject to change
- Feel Free to experiment using different brands according to individual taste
Warning!
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.
Read safety instructions again!
4. Speakers and Cabinets
While you can use your Goldfinger with any cabinets we have special designed matching types. Please
make sure you match the amps impedance with your cabinet like explained in j).
The 2x12 open back cabinet has a Celestion G12H30 and GB25 at 8 ohms total impedance, the 1x12
combo and cabinet uses a Celestion V30 at 16 ohms.
2x12 closed back speakers TBA at release!
Subject to change, depending on availability of Speakers!
For Ultimate Classic Rock tones Reinhold prefers our 4x12 cabinet loaded with Celestion Greenbacks.
