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 JTM/JMP/JCM/2203/2204 Plexi 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 or pressing in turrets as convenient voltage tap wiring, and has pads and multiple wire connection points for mounting radial capacitors for (preamp) power supply filtering.
