Twin Reverb Blackface Mod Kit
This kit includes all of the electrical components, diagrams & written directions you need to perform a full blackface conversion on your silverface Fender Twin Reverb, Quad Reverb, Super Six Reverb & Dual Showman Reverb amplifier to AB763 Blackface specs. This includes the reverb circuit!
(Tools, solder & wire NOT included)
*Complete, detailed, easy to follow instructions with “before & after” diagrams are included.
*Copies of the original blackface Fender schematic & layout diagram for your amp are included! These are invaluable tools for reference & learning about your amp!
*Complete instructions for removing the master volume & push/pull gain boost are included.
*Only the highest quality Nichicon electrolytic capacitors are included in this kit.
*Only the highest quality carbon resistors are used in the signal path. Flameproof metal oxide resistors are used for the high voltage applications in the bias supply.
*Instructions for reading color codes on resistors included.
We now proudly offer NOS rolled foil/mylar signal cap upgrades for our premium blackface mod kits! These selected NOS capacitors replace the standard ceramic caps used in our standard kits (as found in the original blackface amps). The entire preamp signal passes through this one cap on the way to the phase inverter, and the quality of this one cap has a significant impact on the tone and performance of the entire amp. These NOS mylar caps bump everything up a few notches, giving you more depth and dimension (more of a '3D' sound), a bit more clean sustain, and more 'oomph' overall; with smoother, sweeter top end. Don't get me wrong, the ceramic version is excellent and true to the original blackface models! But the NOS version is definitely a significant upgrade, giving you 'more of everything' we like about vintage Fenders!
BONUS: Certain resistors, vital to optimum performance of your amplifier have been measured & matched by tolerance percentage!! You are getting a matched set for your output section! This ensures maximum efficiency, optimum performance and the best possible tone from your Fender! Not only are you converting the circuit, you are optimizing the output stage!
*As a bonus, the necessary resistors & detailed instructions on how to properly set the bias of your newly blackfaced amp (using only a multimeter & calculator) are included.
Another bonus:
I include two brand new Mallory M150 caps to couple the phase inverter output to your power tubes (in many SF twins one of the original caps will be too short to make the “new” blackface connection). If you order a Jupiter or Orange drop signal cap upgrade along with this kit, the proper brand of caps will automatically be upgraded in this kit.
THIS KIT IS SPECIFICALLY DESIGNED FOR 100 WATT SILVERFACE FENDERS: TWIN REVERB, QUAD REVERB, SUPER SIX REVERB, & DUAL SHOWMAN REVERB AMPLIFIERS.
Please note: These kits are designed for the “standard” Fender silverface amplifiers. If your amp is “ultralinear”, these kits are not intended for your amp. You can tell if your amp is ultralinear by looking under the speaker jack on the back panel. ALL 70 watt & 135 watt models are ultralinear!!
