I want a device that takes two audio signals, left and right, and
generates the L+R and L-R signals to the FM specs in use in FM
broadcasting, that I can use with a conventional FM signal generator
like a HP 8640B, 8657A or a service monitor for FM stereo decoder
testing. Is one still commercially available, or is one easily built
such that it can be calibrated with reasonable ease?

There's loads of schematics on the web for these, just Google for 'stereo
encoder schematic' and you'll get over 68,000 results.
