Fender Twin Amp Standard Retube Kit

Product Details

There is a lot of confusion concerning the Fender Twin amps because there is one called "Twin Amp", one called "The Twin", one called "The Twin II", one called the "Pro Tube Twin" and the "Twin Reverb Reissue". So make sure you know what amp you have. This Retube kit is for the "Twin Amp" first built in 1994 and it uses a quad of 6L6GC's for power, five ECC83S's to replace the 12AX7's and three ECC81's with one balanced for the phase inverter.

Tube location info: The Balanced ECC81 is located in V8 closest to the power tubes and the two standard 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.
