Heathkit T4 Guitar Tube Amp Conversion

Embark on a journey of audio engineering and vintage electronics restoration as a Heathkit Model T4 signal tracer is transformed into a guitar amplifier. Learn the process of planning and executing modifications inspired by a Gibson model GA-8T schematic to create a hybrid amplifier. Follow along as the project unfolds, starting with the removal of unnecessary components and the strategic reconfiguration of the preamp section. Observe the careful assembly of new components within the limited space, including the fabrication of a temporary input test point. Gain insights into precise capacitor measurement using specialized equipment and the creation of a temporary center tap tone setup. Witness the exciting moment of powering up and testing the newly assembled preamp side using a variac. This video offers a hands-on exploration of tube amp conversion techniques, blending retro technology with modern guitar amplification.
