Preliminaries - Update - Vintage Tektronix Oscilloscopes

Just an update video. Shelving complete for these old 500 series Tektronix oscilloscopes I look forward to creating restoration videos for. Many common models here - 531, 545, 551, 555, 556, 565 and some others. Interested in learning more about them as I go and sharing some vintage Tektronix restoration and recalibration tips and getting to know fellow collectors and experiences.
