Also note that this module is larger than an original Marshall Plexi board, but will fit in the space available in the cabinet with different mounting points. This board is a full size 297mm x 80mm turret board built on 2.5mm thick heavy duty Paxolin sheet in traditional deep brown.

Likewise, the large can style smoothing capacitors and the output valve bias smoothing capacitors are chemical based, rather like a battery, and the fluids in these components dry up over the years. The higher the value of resistance, the more noise is generated by that resistor.
