Willsenton R8: Power Supply and Output Resistor Upgrade

This video is the first in a set of "upgrade" videos, where I will be replacing some capacitors as well as replacing the metal oxide resistors with less noisy and cleaner sounding metal film resistors. I also find the source of the majority of the hum I heard in previous videos! 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. You can buy this amplifier here The tools I use in this video include: Hakko FX888D-23BY Digital Soldering Station Hakko-CHP-170 Micro Cutter - Red Hakko CHP CSP-30-7 Wire Stripper Long needle nose pliers Also a link to the website to buy tubes, tube rings, volume knobs etc.
