PCBs for Tube Projects

PCBs for Tube Projects

Many of our kits for musical instrument preamps, power amps and power supplies are available with various levels of "completeness". You can buy fully assembled kits, kits that you assemble, just the "hard parts", or just the printed circuit board. In this listing are just the -PCB form which includes the printed circuit board and comprehensive notes for assembly and wiring, and the -HP form, which includes the PCB, notes, and selected hard-to-get parts.. Refer to the parent kit for a complete product description.
