| This is the bare PCB of a PSU PCB for tube preamplifier or other low current tube projects. The board is designed to be used with a 6X4 tube for tube rectification of AC and then regulated by high voltage zener diodes. The board also includes three sets of filament voltage output. The board can be split into two sections at the doted line as shown in the picture such that the high voltage and filament section can be separated into two boards for flexible implementation in the chassis. PCB dimension : 263mm x 63mm. PCB thickness : 1.6mm, 2 oz ( 75um thickness copper) deposition which is FOUR times normal process of copper thickness.Gold plated surface. We provide schematic to buyers by email.We do air shipping worldwide at US$6.00. |
