“PAIA Tube Microphone PreAmp Dual Rack Mount Unit
Includes wall wart power supply. Both units are working. Tested with a phantom powered mic.
All controls seem to work with the exception of the Blend Control on Unit #1/left side.Rotating it to the far right gives no sound, so it will probably need some minor repair. Couple pots are scratchy sounding.” Click here to visit listing on eBay
