Introduction
Thank you for choosing a Cornell
Rambler 15 / Rambler 40
amplifier.
Your amplifier employs valve technology, and is hand built to the highest standards.
Only top quality components are used in our amplifiers, so that you can enjoy years
of trouble-free use.
Please take time to read this manual, to ensure that you get the best from your
Rambler 15 / Rambler 40
amplifier.
Construction and Design
Virtually all modern amplifiers are built using printed circuit boards, which helps to
speed up production and keep down costs. There is, however, one major drawback
with printed circuits - conductor tracks that connect components together often run
very close to one another, creating a small capacitance. The result of this in a
guitar amplifier is a substantial loss in both high frequency response and harmonic
richness.
Cornell amplifiers are designed to avoid this by having point-to-point wiring
throughout. Components are mounted onto a specially designed component board
which is then sealed, using a conformal coating to prevent noise and the reduction
of component life caused by moisture penetration.
The hand wiring, carried out by our highly-trained staff, takes time but ensures that
each of our amplifiers performs to the highest standards of reliability and sound.
The stainless steel chassis holds our specially-designed transformers, and chassis-
mounted (rather than circuit-board mounted) valves (tubes).
Such attention to detail ensures a very close reproduction of the full harmonic
spectrum of your guitar’s pick
-ups, resulting in a pure, natural sound that will turn
heads at any venue and/or that records superbly.
