2.1.4 Operating Temperature
It will take a little more time after warm-up until everything inside the amp is working in sync and
to it’s fullest potential. A trained ear will notice a slightly warmer tone and better complexity in
tone after playing the amp for a short while. It’s like warming up before running a marathon. Get

2.1.5 Power Tube Life
The power tubes of your amplifier are subject to a certain aging process. Once one of the tubes
shows signs of aging, unreliability or unusual noise, then we suggest that you replace all power
tubes. Matched tube sets wear relatively even, or so our experience suggests. This means if one
goes, the others are not far from meeting the same fate.
The aging process manifests itself by a depletion of a thin layer of Wolfram on the Anodes. This can
take anywhere from 6 month to 3 years, depending on the amount of use of the amplifier. The
amount of wear is determined by the amount of performance that is asked from the tube.
Chapter Three: Peripheral Connections
3.1 Front Panel Connections
3.1.1 The input jack (“IN”)
The input jack receives your Electric Guitar signal by means of a shielded guitar cord with 1/4”
mono style plug.
Your guitar cord is an important part of your signal chain and its quality and construction type
clearly affect the overall tone of your rig. Try and buy the best quality guitar cord that you can or
want to afford. Call us if you have doubts and need recommendations. This is where the smart
“weak link” comment comes in. Get it?
3.1.2 Cable ABC
Some cords and cables sound very neutral; others color the sound spectrum and/or attenuate high
frequencies due to capacitance inside the wire and shield. What are we talking about? OK. A
capacitor is used in electronic crossovers, amongst other things, to divide low and high
frequencies. Capacitance in a cable therefore cuts your guitar’s high end to a certain degree.
Generally, the longer of a cord you use, the more of the cords inherent characteristics will be
audible.
