mbled with service and repair in mind. I have always had a very deep respect for the design and performance that tube amps produce. Let's face it, guitar tube amps don't always get the respect that they deserve. Tube amplifiers have always worked hard and should be looked at as a major part of your sound as they inspire you to dig deep into your playing. If you feel somewhat the same way I do about tube amps, then you know each amplifier has their own characteristics and tone. I hope you can use this educational information to understand how tube amps are designed and how they work.
