Bill Thallman originally designed the amp as Technical Director of CJ Design & performed the $500 upgrade/renovation on 3/8/07 (see invoice photo) including: 

1.   Premium high-voltage regulators
2.   Cardas Rhodium RCA input jacks (photo)
3.   Damping sheets under chassis & inside top (photo)
4.   Van den Hul pure silver & silver-plated wire (photo)
5.   Signal Cable power cord, 41" amp to plug tip (photo)
6.   Cardas Rhodium 5-way speaker binding posts (photo)
7.   Hyperfast soft-recovery diodes replace OEM bridge rectifier
8.   Premium input coupling caps (required circuit modifications)

200/350WRMS 8/4-Ohms; two pair MOSFET output devices (especially well suited to electrostats/ribbons) per channel; rich detailed upper mid-treble & great stage/image performance.  Stone cold blew away a fully warmed/burned-in $2800 Italian Pathos Acoustics Classic One hybrid/MOSFET (then a Stereophile Magazine Class-A Recommended Component); also soundly trounced (as expected) a $1000 US-built ATI #1802 200W bipolar amp.  The MF200 has excellent power, staging, imaging, refinement, resolution & transparency; the better qualities of tubes w/ none of the cost, heat & service hassles.  No listening fatigue regardless of duration; very musical.     

Rock solid reliability; never hiccupped or made inappropriate noise or vibration of any kind, mechanical or through the speakers; never blew a fuse, no service required, top never removed except for photos.  Dead silent power up/down.  Heat-sinks barely warm at any playback level; amp is a gem at a great price.         

Includes OEM Owner Manual; brand new unused OEM shipping carton from CJ; inputs/outputs/fuses/fuse sockets/AC plug all treated w/ Caig Pro Gold; all fuses to OEM spec.
