Based on a design originally developed for laboratory grade test equipment, as well as military use, the 1201B+ Power Supply is a tube regulated unit that has been completely updated and optimized for the 1.1 Phono Stage and 1.1 Control Preamplifier.
Features include:
- Universal AC mains transformer for worldwide operation
 Tube rectification for slow turn-on
- Complete protection via three front-mounted, fast-acting, circuit breakers.
There is one breaker on each of the hot and neutral primary lines to protect the transformer, plus one on the center tap to protect the circuit. There is no longer any need to search for fuses when there's a problem or to disassemble your system to replace them. Plus, they sound better!
- User adjustable B+ output from 250 - 300 Volts DC (260 VDC recommended)
 Highly regulated 6.3 Volt filament supply, accurate to within 1/2 of 1%
- Illuminated DC Voltmeter
- "Cost no object" parts including Vishay-Dale Mil-Spec resistors and Solen polypropylene film capacitors throughout the B+ supply. There is only one electrolytic capacitor in the entire component, a 10,000uF value in the 6.3V supply.
- Soundcare® SuperSpikesTM for increased protection from airborne and mechanical feedback
- Furutech FI-10 IEC AC inlet
A high quality, fully-shielded, 6' (1.8 meter) 14 AWG detachable Quail AC line cord is supplied with every unit. This can be upgraded to the Tempo Electric CS Power Cord. The CS (for Common Sense) is a hand-made AC line cord fabricated from 12 AWG, Teflon® insulated, fully-shielded, silver-plated copper wire. Available in any length, both ends are terminated with WattGate Audio Grade power connectors.
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.
The 1201B+ Power Supply is included in the price of all preamplifiers. While one supply has sufficient amperage to power both channels of any Arthur Loesch Preamplifier, a pair (one for each channel) will provide the ultimate in listening pleasure.
