The kit includes all Made in USA transformers, High Quality Hand Made 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 40-18027, TF103 Output Transformer or 40-18031, Replacement Filter Capacitor, two 8 pin Belton sockets (6V6,5Y3), two 9 pin Belton socket (12AX7 x 2), Potentiometers are CTS or Alpha, two 250k potentiometers (Tone Controls), one 1M potentiometer (Volume Control), one 3M potentiometer (Vibrato Speed), one 25K potentiometer (Vibrato Intensity), 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 JJ 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 ultra linear 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!!!
