- Page 2 Introduction The design brief for the Bonneville was simply to build a single channel all valve guitar amplifier. Although it only has one channel, it can produce a wide range of tones due to the design of both the preamp and power amp sections.

Page 3: Front Panel Controls
FRONT PANEL CONTROLS Input A single jack socket is provided for connection to your instrument. This is a high impedance input which allows for perfect matching to both passive and active guitars. Gain This control adjusts the degree of drive in the preamp stage. This is used in conjunction with the PREAMP STYLE switch to set the amount of overdrive required. -

POWER AMP CONTROL Speaker output socket & impedance selector switch The Bonneville has connections for driving loads of 4Ω,8Ω or 16Ω depending upon which socket is used and how the switch is set. In one position the two sockets are for either 4Ω or 16Ω, as indicated on the unit, whereas with the switch in the other position either socket can be used to drive an 8Ω... - Page 5 Therefore, as an example, if two 8Ω cabinets are used, 8 x 8 = 64 = 4 so the 4Ω socket should be used. 8 + 8 16 Output Damping The OUTPUT DAMPING control determines how much effect the speaker cab has on the output stage. High damping, with the control fully anticlockwise, provides a lot of negative feedback which basically attempts to correct any distortions that are occurring in the output stage and speakers, this produces a tighter, cleaner sound with flatter response.
- Page 6 Six 12AX7’s are fitted to the Bonneville amplifiers and are used as follows:- Combo Version Looking at the unit from behind with the rear panel removed, the second row of three are for the actual preamp gain stages, the right hand valve being the input stage and therefore the most sensitive.
