Tektronix 7904 Oscilloscope Mainframe

Got a classic Tektronix 7904 oscilloscope mainframe here. This was the top of the line back in the day with a 500MHz bandwidth. It's the mainframe only, so you'll need to pop in your own 7000-series plug-ins to get it going. Doesn’t seem to power on but have no modules to test with. Great for a vintage lab setup or if you need a solid base for your 7k gear. Has some dust from storage but overall looks decent for its age.
