I have a set of Nak 701's that I want to convert to Phantom power if possible. I rewired them 28 years ago, they are on semi-permanent loan from a former taper. They came with female RCAs on the end of mics, orig. taper had intermittent signal loss, I replaced with BNC connectors. Orig. mod battery box had wrong components, low signal. Got a mod battery box that had proper wiring and components from Rob Gilde and replaced all connectors on it with BNCs. That solved all issues, but now I want to run them into either my Tascam dr100mk3 or into my dr40 if possible. Melanie already has 4v's for her Tascam HDP2. Any advice would be appreciated. Bob
