JLM Audio Scorpion 30W tube power supply. 6-12v Filament, 48V & 2 × 50-300v power rails all regulated and trimpot adjustable.

Switchable 115vac/230vac. VS sync allows syncing multiple Scorpion & Power plants with one 115vac/230vac voltage selection switch.

Easy heatsink or case mount with only 2 screws to tension regs down. Fits on the bottom of 1 unit high case (if you have 39.6mm internal height) or side of 2 unit high case.

Regulator metal tabs face away from the PCB so they will press against metal case inside the insulating silicon tubes.

Power Plant PCB 7.75" (198mm) x 2.5" (63.5mm)

Scorpion 30w wattage calc 

300v high voltage setting = 21 x Filament current + 320 × HV1 + HV2 current = 30W or less.

150v high voltage setting = 21 x Filament current + 160 x HV1 + HV2 current = 30W or less
