Proton 830R (circa 1986)

Little is documented about the Proton 830R. What the record shows is a single period sighting: a Wisconsin Discount Stereo advertisement in HiFI-Stereo (May 1986, p.122) lists the Proton 830R among the store's featured specials at $269. That's essentially the whole surviving trail.

Given the model number and Proton's mid-1980s lineup, the 830R was presumably an audio component — likely a receiver or amplifier — but no specification sheet, review, or owner documentation has turned up to confirm its output, features, or production run. The surrounding pages of the same magazine advertise Proton's AV27 audio-video system heavily, but none of that material refers to the 830R specifically, so it can't tell us anything reliable about this model.

If you have a brochure, manual, or even a clear photo of the rear panel, the archive would love to hear from you — this one is genuinely undocumented.
