Blank chassis medium
Medium-size chassis, blank for your own amplifier layout
This chassis blank is made from 1/16in (1.6mm) aluminium, cut and folded to create a chassis that’s suitable for both head and combo amps. It mounts like a vintage Marshall chassis, via four M6 cage nuts on the flanges, but the front and rear sides of the chassis run full-width. This makes it suitable for both vintage JMP-style amps, and modern-style amps, where the opening in the cabinet is as wide as possible so as to provide room for more controls, inputs and outputs (e.g. Soldano, Marshall JCM style).
The flanges are pre-punched with the square holes for cage nuts (see below). The outward-folded flanges ensure that the M6 mounting screws do not enter into the amplifier chassis – for safety – and allows unimpeded access to the internal components.
Dimensions & info
The chassis is 483mm wide, 170mm deep, and 65mm tall. The internal dimensions are 440x167x63mm – about the same as a 50W JMP Marshall chassis, and plenty enough to accommodate typical medium-output valve amp designs. Made in the UK. For details of mounting hardware, see the hardware section.
