Hello Everyone, this is up on Ebay, Thank you for looking... and bidding! 
Millennia Media HV-3 Stereo Mic Preamp
Fabulous sounding preamplifier in excellent condition.
The standard for clean, transparent preamps.
It was recently checked at Millennia Media and upgraded with DC Input Option for ideal performance with dynamic and ribbon microphones. Was also upgraded for higher gain (78 dB). I bought this preamp used less than a year ago and I only used it on one project. This preamp sounds great.
