JMP/2203/2204 ST1 Circuit Board – Red

Our red ST1 printed circuit board was originally created to replace damaged or non-repairable ST1 boards. It has all the same component placements, traces, and mounting hole locations of the original. However, we improved on the original design! Most importantly, it is double-sided with though-hole plating (unlike the original, which was single-sided with thin copper). It can also be dual-purposed to use in any JMP/JCM/2203/2204 style amp build. It has extra component holes/pads for either box style or axial capacitors in the coupling caps placements, has turret-sized holes on the supply/rectifier end for soldering in turrets as convenient voltage tap wiring, and has pads for mounting radial capacitors for (preamp) power supply filtering.

Top side has component location (outlined) silkscreening. To facilitate multiple wiring/value options, component values are not printed. A perfect replacement board for vintage Marshall, Marshall-style amp, or any JMP/JCM800 style amp.
