Power supplies, particularly high-voltage power supplies, are often the big stumbling block to a successful completion of a tube-based audio project. Getting a PCB and all the capacitors, diodes, and resistors needed to populate the PCB is only half the problem. The other half is getting the power transformer. Well, with the new Tr-PS-2 power supply both problems are solved at once, as the Tr-PS-2 holds its own power transformer. The Tr-PS-2's PCB is only 5 " by 2.8 " and, like all GlassWare PCBs, is extra thick (0.094 in), US-made, with heavy 2 oz-copper traces.
Brother to the Tr-PS-2, the Tr-PS-1 is a low-voltage, regulated 12Vdc (or 9Vdc or 12.6Vdc) power supply, perfect for powering vacuum tube heaters or replacing the wallwart power supply that powers DACs and other small audio gear. The Tr-PS-1 holds its own 36VA power transformer. The Tr-PS-1 PCB is only 5 " by 2.8 " and, like all GlassWare PCBs, is extra thick (0.094 in), US-made, with heavy 2-ounce copper traces. The PCB holds a 3A, low-drop-out (LDO), adjustable voltage regulator, the LD1085, which idles at 10mA with no external load and is able to deliver 1.5A @12Vdc into an external load.
