  At the Buy It Now price I am offering you a raw (but mostly working) Tek SG503 Leveled Sine Wave Generator plugin for a tiny fraction of what it cost new, about $4000. These were introduced in the late 1970s to replace the Tek 191. The early versions looked like those in the first photo. Later versions were introduced in the mid 1980s (remainder of photos) which had improved the bottom latch. If you want a newer version, please offer $150 more; yes, ebay lets you offer more than BIN). I can refurb, freshly calibrate and guaranty it for 90 days (versus none) for $300 more. SG503 generates 50KHz to 260MHz at 5mV to 5V rms (into 50 ohms) and is used to check scope bandwidth, and their attenuator flatness. SG503 needs to sit in a TM5__ power box to work, eg: TM503 or TM504, which can be found widely and quite inexpensively on the used market. In the late 1990s Tek sold the 5__ line to Tegam (in Ohio). Tegam continued making them for a decade, then quit.  If you offer less than BIN, you may get one that needs repair and/or parts. Thanks for understanding that what you get depends on how much you pay. If you need more clarity, please ask questions.  Since I have/had more than 1 for sale, the 1 in the photos may not be the 1 you will get.  I ship worldwide. Ebay & Paypal require I ship by carrier/method that includes tracking & delivery confirmation, which public Airmail is not good at. Foreigners may save on import tax by paying separately in a 2nd Paypal for any of the extras I offer, as the 2nd would be invisible to your country's customs.  California resident buyers pay sales tax. I leave feedback after you do.
