Willsenton R8: Power Supply Mod and Upgrade



Published
In this video I am replacing the resistors and caps under the power transformer, as well as eliminating the 115/230 switch and installing 18ga solid core twisted pair power wiring.

This is a video series about the popular Willsenton R8 KT88 EL34 Push Pull tube audio amplifier. We will go through the repair this amp needs, testing and reviews of the amp as delivered, and then work on modifications to improve the sound quality and durability.

A great book for DIY amp building info!
