Recently finished up this newest custom PM1000 rack for a client. Original Tamura Input transformer, Classic API 2623-1 Output transformer,
DI Input, 48V Phantom Power, 20 dB Pad, Phase reverse, changed the mid-frequency selections to 800, 1.6, 3.1 kHz, re-capped, transistors swapped,
Output trim added, and used a little LM317 voltage regulator circuit for the proper +44Vdc supply rail to the PM1000. Voila!
the Buffalo PM1000
