We're on our annual big city vacation to Portland this week. Today was TEA day. I did my annual trip to Surplus Gizmos and despite numerous temptations as seen in the first 2 photos, I managed to escape only spending $7 on a large 4 conductor 10 AWG cable I plan to use to make a generator cord with.
But nearby I stopped to pick up a Tek 475 that I spotted on Craigslist. Ryan, a very nice test engineer from Maxim had a few 475's each with issues and each for only $35 each. Since I already have one at home that has one non-functioning channel, I figured I could justify buying one more at that price as a parts donor if nothing else. It turned out to be one in reasonably good condition. A quick test showed decent traces on both channels but with some issues. But for $35....how could I not take it!
Ryan had a whole garage full of gear - much of it old ham gear but also some test gear which he apparently diverted from a fate in the Maxim dumpsters. I spotted a stack of 5 Data Precision 8200 voltage/current calibrators which he said he planned to sell after he'd had a chance to test them, etc. Since i expressed an interest we powered them up. All powered up fine but all had some issues with inconsistent or no response to knob/pot turning - they'd been used via GPIB only apparently. With my wife and kids waiting and no time to do any real testing, he convinced me that I needed 2 of them and for $20 each how could I say no....
