Hiwatt DR103 Bias Circuit EXPLAINED | Stock vs Modded

Having trouble dialing in the right bias voltage on your Hiwatt? In this video, I break down the stock Hiwatt bias circuit and compare it to a popular voltage doubler bias mod using LTspice simulations. We will walk through the stock and voltage doubler circuits by first looking at the schematics and then simulating each in LTspice. You'll learn how to get a more flexible bias circuit that accommodates for modern tube variances, and understand what’s really going on under the hood. 00:00 Intro 01:24 Why Do We Need Bias? 04:21 Hiwatt Stock Bias Circuit Walkthrough 08:06 Hiwatt Voltage Doubler Bias Circuit Walkthrough 13:56 Circuit Simulations 18:27 Final Thoughts #hiwatt #guitaramp #amprepair
