Punched chassis medium 2x8 and 3x9

Medium-size, holes for three preamp valves and two octal power valves

Sale!

ON CLEARANCE: This chassis is a version of the medium-sized plain aluminium chassis, but pre-punched with a range of holes to suit Amp Maker kits and many other typical projects up to 20W or so. If you don’t have metalwork tools, or the necessary skills and patience (like me), this chassis can cut your amp assembly time right down.

 

Transformer mounting
It has been punched for a stand-up or frame-type power transformer such as the framed version of the 0-190-275V power TX. There are also mounting holes spaced to suit the 5W single-ended, 15W single-ended and the 18W push-pull output transformers.

 

Control and other holes
The rear panel has holes punched for a combination IEC+fuseholder socket and three speaker outputs. The front panel has holes punched for a range of toggle switches, indicator lamp, pots and jacks sockets. The top surface is punched with the transformer mounting holes mentioned above, plus five valve socket holes: three for 9-pin sockets and two for 8-pin sockets. The top surface also has M3 mounting holes for fitting the circuit board(s), and several M4 holes for fixing grounding lugs, tag strips, etc.

 

Dimensions & info

The chassis is 483mm wide, 170mm deep, and 65mm tall. The internal dimensions are 440x167x63mm – plenty enough to accommodate typical amp designs. It’s suitable for both head and combo amps and mounts like a vintage Marshall chassis. Made in the UK.
