Hello all audio Gurus. I'm new to this forum, reading as much as I can with interest. I have a Harris PX-91 broadcast phono preamp. Seems to be a very cool item, OP37 input stage followed by NE5532, balanced XLR line level output.

I cannot find a schematic for it. Before I draw one out myself and cause headaches and ulcers, does anyone have one? BAMA does not. Also looking for a source for Linear OP37 op amp, just in case. This thing does work, but I like having spare parts handy. I am also planning on re-capping it and replacing the highly oxidized input RCA and output XLR connectors. Thanks.

Relocated to Analog Source since this is a Phono Stage.

Welcome to the forum and good luck in your quest!

Have you checked over at Vinyl Engine - The Home of the Turntable to see if they have anything on your phono pre-amplifier? (Note you do have to be a member.)

Mouser.com has a few hundred 8-DIP in stock. More of the surface-mount, but that would be awkward.
