Fender Twin Amp Gold Pin Option

Product Details

Gold Pin Option for the Fender "Twin Amp" with a matched quad of the JJ 6L6GC's, five Gold Pin ECC83S's and three Gold Pin ECC81's with one balanced for the phase inverter in V8. Really Smooth!

Tube location info: The Balanced Gold Pin ECC81 is located in V8 closest to the power tubes and the two standard Gold Pin ECC81's are located in V2 and V3.

All Combo amp Retube Kits are shipped with the Eurotubes Double Mica 6L6GC’s at no extra charge. JJ Electronic started building us a proprietary version of their 6L6GC (the 6L6GC-DM) in 2005 with extra layers of mica. This reinforces the plate structure and all but eliminates tube rattle symptoms.

All you need to adjust the bias on a Red Knob Twin is a multimeter. These are are available in the "Related Products" tab.

Set power switch to high, nothing plugged in to the input. Turn all gain and volume controls down to one. If your amp has vibrato set both speed and intensity to one. Foot switch unplugged. Reverb down to one.

Now stick the red lead into the middle test hole and leave it in there. Stick the black lead into the hole marked BIAS 0.08V read what you have on the meter, and adjust the trim pot marked "OUTPUT BIAS ADJUST" until your meter reads .080 volts.

Now pull out the black lead and stick it in the hole on the right marked "BALANCE 0V" and adjust the meter to read zero. Let the tubes get hot and settle, then check and readjust if necessary.
