We have a range of plain aluminium chassis, punched, unpunched and undrilled for use as a Marshall or other type chassis.

The blank chassis are 508mm (20") long and 152mm (6") wide and 64mm (2 1/2") high. They have a 15mm lip with M6 inserts fitted 100mm (4") from each end.

They are made from top grade Aluminium in 1.6mm material.

We also offer a prepunched chassis of the same dimensions as the plain chassis, with the front panel left plain for your own faceplate.
Both chassis have a superb finish that resembles brushed stainless steel, when the plastic coating is removed.

All chassis include 4 X M6 chassis inserts.

The transformer hole is cut to suit the standard RS type imperial mains transformer. Available from ValvePower.

The punched chassis is punched for up to 6 of the popular 22mm ceramic 9 pin valves sockets and a 33mm hole for a can capacitor if required.

The plain chassis is £10 plus £3 PP to UK, £6 to most of Europe and £20 for the prepunched (£3 UK PP)
