Description: MM5A: Fully-Discrete, Zero Negative Feedback, Single-Ended Class-A High-Voltage Pure J-FET (Junction Field Effect Transistor) Phono PreamplifierWhy settle for underwhelming performance from the well-known names?Get *truly high class” sound with hand-built USA quality, from an engineering team with 50+ years experience.Zero Feedback, Single-Ended Class-A Gain Stages - No Op Amps (Integrated Circuits) and no Differential FET operation - for more natural sound, cleaner crescendos and minimal listening fatigueUnique Power Supply Regulation - Derived and simplified from our top of the line model (the MP8B), our MM5A is a simplified single-channel version supply derived from the MP7B. It provides clarity of sound, 'punch', good soundstaging, power and dynamicsHigh Headroom Passive RIAA equalizationHigh-Voltage J-FETs -Hand-matched with hand-tuned operating points deployed in a maximum-inherent-linearity configurationExtensive local decoupling networks provide deep, wide and immersive soundstagingLED Color is Blue on the MM5A (no other colors).Hand-soldered, assembled and calibrated by experienced US-paid craftsmenThrough-hole construction for electrolytic capacitors and other critical parts, conservatively rated, long life audiophile quality componentsListen 3 to 5dB louder without strain or fatigue than competitive products for greater perceived dynamics and musical immersionInvites comparison to products up to $1000 or more. DETAILED FEATURE LIST: Resistive loading: 47K (fixed) Capacitance: 100pF Gain: +40dB at 1kHz. Balanced Power Supply Generation (BSG) for low background hum in even difficult or dirty AC line conditions. +60V Main Voltage Rail provides excellent headroom for good sound and low audible surface noise. LED Color: Blue (only). SPECS:Distortion: 0.1% THD at 0.5V out, 1kHz into 10K load; 0.01% 3HD and higher, 1kHz at 0.5V into 10K loadS/N: 76dB A-Wtd re: 5mV input with simulated inductive standard MM type cartridge as a source (40dB gain)Maximum Output: 18V RMS (26.5dBu or 48V pk-pk) at 1kHz into 10K load.Frequency Response: RIAA: +/-0.25dB from 20Hz to 20kHzBandwidth: -1dB at 9Hz and 60kHz.Input Overload: 140mV at 1kHz input. Size: 7” D x 5 1/8” W x 1 9/16” H. Weight: 2.2 lbs. Packed weight: 3.3 lbs.External Power Supply Cube: 24VAC 500mA, available in US 120V, EU 230V, UK 230V or AUS/NZ 230V. **NOTE: THIS IS AN EBAY-EXCLUSIVE MODEL****SIGNIFICANTLY MORE INFORMATION ABOUT OUR LARGER PRODUCT LINE IS AVAILABLE THROUGH OUR MAIN DISTRIBUTION CHANNEL (we cannot link to it here due to eBay policy but you will very likely find it easily by using traditional web search techniques)**
