Bassman 50 & 100 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 Bassman 50 or Bassman 100 amplifier, converting it to the coveted AA864 blackface bassman output circuitry!

If you have an “AB165″ bassman, then our “AB165 to AA864 conversion” kit is for you.

(Tools, solder & wire NOT included).

*Complete, detailed, easy to follow instructions with “before & after” diagrams are included.

*Complete instructions for removing the master volume & push/pull gain boost are included (where applicable).

*Only the highest quality Nichicon electrolytic capacitors are included in this kit.

*Only the highest quality carbon comp resistors are used in the signal path.  Flameproof 1W metal oxide resistors are used for the high voltage applications in the power supply & bias supply.

*Instructions for reading color codes on resistors included.

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 blackfacing the circuit, you are optimizing the output stage!

The tolerance normally associated with resistors makes it almost impossible to find matched sets unless you have hundreds & hundreds to choose from, & the time to sort through them all.

We have taken readings on literally thousands of resistors and spent countless hours putting these matched sets together.Why?  Because matched sets sound and perform better than unmatched!  Most kits on the market today do not take the time to provide this important service.

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.

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!!
