6T9 4.7W DIY Tube Amplifier in a Baking Pan

A Tube amp kit based on Spare Time Gizmo's printed circuit boards which are plated through, solder masked and screen printed. I sourced common components from the local electronics shop but used a pair of NOS GEC 6T9, Alps potentiometer, solid brass knob and a Hammond power transformer. The chassis is a Teflon coated backing pan ($7). The OPTs are custom wound toroidals. The amp is a little bass shy. Doubling the 100uF power caps helped increase bass. See the 6T9 Tube Amplifier Project for more details.
