Heavy Duty Amplifier Chassis Baseplate

A custom heavy-duty baseplate for the Modushop 300mm deep chassis ideal for dual mono amplifiers.

Product Description

Originally designed by one of our founders in his quest to develop a dual-mono Amp Camp Amp (an amplifier design by Nelson Pass) Aileron Labs is proud to make available this limited edition custom heavy-duty baseplate.

This replaces the baseplate on selected 300mm deep Modushop.biz chassis as required to support heavier components without bowing. This may be used to duplicate the dual mono amplifier configuration as shown, saving a LOT of custom machining in the process, or modified for a custom application. As with all DIY amplifier builds, the choice is yours!

We have no plans at present to produce another run of this part so when our supply is exhausted, that's all folks! Get one while they last!
