Kit for TT PSU Mini

The kit includes all components except a powertransformer and a choke for building PSU for tube amps. If you want to use a choke instead of the 5 W resistor than you must order the choke that you need separately.
The PSU can handle max 700 V DC at out B1 and B2, 450 V DC at out B3 and is recommended for tube amps up to 50 Watt. The size of the PSU is 97 x 55 mm only and has a high of ca. 40 mm.

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

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

R.F. DOUBLE TRIODE

ECC99 is a 9-pin double triode usually used as a driver for directly heated power triodes (i.e. 300B and 2A3), but in some applications can be used as power tube (headphones amps, small power amps...).

Tube-Town 12AX7 / ECC83 Preamp-Tube

The TT12AX7 impresses with its fine and detailed reproduction of the highs, which is maintained even at high amplification levels. Due to a higher H3 part, the TT12AX7 sounds significantly cleaner than many other 12AX7/ECC83 tubes, which makes the bass range appear much tighter. We therefore especially recommend this tube for styles such as clean, crunch, and metal, where high amplification and clear transparency are required.

Application Notes

• Heater operation: The tube can be operated with 6.3V or 12.6V, depending on the circuit design.
• Grid resistors: It is recommended to use grid resistors of at least 1MΩ to ensure stable functionality.
• Coupling capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.
