Hi. I have an old Teac 2A mixer that I want to update with new chips. The mixing op-amps are 5558's so I know what to do there, but the preamps use a TA7136 device. I do not know what these are and can't find information on it in the web. Do any of you know what this device is, and better yet, have a data sheet on it that you'd be willing to share? I want to replace it with a new IC, preferrably pin-compatable. Please help.
