Have to dig into the details, but I could see it. I've driven VFD filaments from the much older LM1877, before National got swallowed up by TI. Its a stereo amp, which I rigged in a "bi-phase" configuration, much like the LM4871. All these parts belonged to National. I wonder if that employee was a National employee, and came along with the acquisition ?
