Based on a design originally developed for military and laboratory test equipment, the 1201B+ Power Supply is a separate tube regulated unit that's been updated and optimized for the Enigma Mono Preamplifier.
Although set for lowest ground potential prior to shipping, if required, AC phase can be reversed by switching the hot and neutral lines inside the chassis. Even if reversed, the power supply is always protected by independent circuit breakers on both sides. The convenience of front access, "push-to-reset" breakers eliminates the bother of fumbling with miniature fuses in hard to reach locations.
- Universal AC mains transformer for 120V or 240V worldwide operation (user switchable)
- Tube rectification for slow turn-on
- Complete protection via three front-mounted, fast-acting, circuit breakers.
- User adjustable B+ output from 250 - 300 Volts DC
- Highly regulated 6.3 Volt filament supply, accurate to within 1/2 of 1%
- Illuminated DC Voltmeter
- MilSpec parts throughout
- Furutech FI-10(G) IEC AC inlet
- A shielded, 6' (1.8 meter) 14 AWG detachable Quail AC line cord is supplied with every unit.
The 1201B+ Power Supply is included with the Enigma Mono Preamplifier (only one unit is required).
