Help! Specs/datasheet/manual for Curtis Tech OPRE2 needed...

Hey all,

sorry for posting again so soon but I'm getting a bit more desperate. Does anyone have any specs or even better a copy of the datasheet or manual for the Curtis Technology OPRE 2 (or OPRE 8 as I guess they're fairly similar). I am trying to find out the maximum gain, input impedance, noise measurements, etc.

Also does anyone know how these preamps are with ribbon mics (such as beyer m160 or aea r84?).

Finally, failing any of that info... how would I test a preamp to find out the input impedance or maximum gain. Unfortunately I haven't got access to an analog oscillator or oscilloscope.
