AA764 Blackface Champ DIY Tube Amp Kit

DIY Build or Rebuild Kit for a Blackface AA764 Fender Champ Amplifier. Your little Champ will sound better than ever before, and provide years of reliable service. The kit includes all Made in USA transformers, a High Quality Handmade in USA turret board, High Quality Carbon Comp Resistors, and Sprague Orange Drop or Mallory 150 Series capacitors, our 5F2 champ power transformer or Laydown Dual Voltage transformer (see dropdown menu), TF103 Output Transformer, Replacement Filter Capacitor, Belton sockets: two 8pin sockets (6V6,5Y3), one 9 pin socket (12AX7), CTS and Alpha potentiometers, two 250k potentiometers (Tone Controls), one 1M potentiometer (Volume Control), Three Chicken Head knobs, Switchcraft Jacks, Carling Switch, Fuse Holder, Lamp Holder & Jewel, & Power Cord. The kit also offers some flexibility for those who aren't afraid of experimenting. The Filter cap is a 40-20-20-20 @525V so you could try some different power supply filtering configurations by paralleling two sections for a single 60uF. The output transformer has outputs for 4 and 8 ohms as well as ultralinear taps aka Dr. Z amps, if you wish to use them. We will also throw in enough Cloth-covered Pushback wire to do the job. Tear the guts out of that solid state combo and build this inside. Great for DIY Builds. All you need is a Chassis, Cabinet, & Speaker!!!

We also offer the kit with the option of a dual primary 120/240v laydown transformer, 40-18027. (see drop down menu)

TF103-48 output transformer is now available with EITHER 2 3/8 inch mounting hole centers (fits silverface & blackface Champs from 60's & 70's) or 2 inch mounting hole centers (fits later model Champs). Or you may use our 15W SE OT (40-18031) for increased headroom and wattage capability! (see drop down menu)

All Transformers are Made in USA, in Chicago, IL, by a company with over 50 years experience making high voltage Transformers for tube amplifiers.

Transformers are warranteed by the manufacturer against defects of materials & workmanship for 6 months from date of purchase. Board is shown built for demonstration only, kit is unbuilt. Check out our cabinets and chassis to complete the scene. Get the iron hot.
