Kit TT PSU Mini Center Tap

Standard power supply for power transformers with center tap. NOT recommended for tube rectifiers because the first stage has a capacity of 100 µF which is too much for most tube rectifiers. Some capacitors need to get changed if it should be used with a tube rectifier (further informations in the datasheet).

The kit includes all components except a power transformer and a choke for building a PSU for tube amps. If you want to use a choke instead of the included 5 W resistor you must order the choke separately. The PSU is recommended for tube amps up to 50 Watt. The size of the PSU is only 97 x 55 mm and it has a height of ca. 40 mm (without spacer bolts).

Please refer to the attached schematic for more informations about the layout and design of the PSU.

Tip: use Duncanamps' PSU Designer to simulate and calculate power supplies.
