JMP/2203/2204 ST1 Circuit Board – Black


Now available in black (solder mask). Our 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. 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 placement positions, and has turret-sized holes on the supply/rectifier end for soldering or pressing in turrets as convenient voltage tap wiring, and for other wiring points (choke, screen supply, etc.)

Top side has component location (outlined) silk-screening. To facilitate multiple wiring/value options, component values are not printed. A great replacement board for vintage Marshall, Marshall-style amp, or any JMP/JCM800 style amp, and also for similar amp builds. Please note: No layout is provided. For component values and placement, use an internet search. There are plenty on online reference materials available.
