5W Guitar Valve Amplifier Kit - Fender 5F1 Champ Style   

  This is our take on the famous Fender Champ Guitar Amp from the 50s. It offers a beautifully rich, creamy sound with a lovely warm bass and mid response that you can only get from a valve amp. When we tested this kit for the first time it's sound surpassed all of our expectations and we are all super excited to share this experience with you.

  Using a high voltage DC-DC boost converter instead of the conventional power transformer and rectifier valve, this amp kit is lighter, smaller and more cost effective without compromising on the performance. Since the boost converter requires only a 12V DC input, this amp can also be used on the go, and can even be powered by 12V batteries. Our design also includes a cathode bypass capacitor on the first triode gain stage to increase the gain, this is a common modification done to the original amp and we think this makes it sound better. If you want the original sound this capacitor can be omitted.

  We recommend using a 12V power supply that can supply at least 5A like this one BSM1250.
