content: My first try in a long time to attach pix...The A/D drift is easy, I just check the 732B voltage.The 732B runs in opposition to the eight 732As that I've collected over the years.This herd is scanned by hand on a Data Proof 160 and read out on an oldKeithley 181 nVoltmeter. I keep a 9x9 matrix of the voltages to a uV, 0.1ppm.The 4214 L&N 10Kohm is the other artifact needed for the 3458 tracking.The hope was to get about $4K on fleabay.

content: The units all are very stable. eBay flippers buy drifty junkers and sell them for top $$$.I did get one of these over a year ago and sure enough, bad A/D and bad A9 reference.I'd rather sell them to volt-nuts here for less $$, since the 10% fleabay fee wouldn't apply.Also, on fleabay, they would be listed as 'parts' machines, at avoid the scammers complainingto get a refund. (sigh)

content: Quote from: alanambrose on November 03, 2020, 06:37:07 pmeBay has been very stringent against sellers - pretty much if the device has a single problem, however small, a buyer can claim false ad and eBay will intervene.I never did such large $$$ sell on eBay, but with small parts (computer memory, for example) I used to create a short movie in a single shot that showed it working, its serial number and the packing process - in case someone claimed otherwise.

content: For parts protects the seller against scammers.I showed working pix to let legit buyers know that it works fine.ebay takes 10% and paypal takes 3% right off the top,and includes the price of shipping with the sale price.

content: >>> For parts protects the seller against scammers.Yeah but if I'm a buyer, buying a $3-4K item 'for parts' that the seller claims in a side channel 'is actually working' sounds like a recipe for:"item turns up with all the pcbs removed and buyer has no protection"... which sounds like to much of a risk for me. Not that I really need another 3458a.Alan

content: Quote from: acts238willy on November 02, 2020, 06:58:23 pmThe way to prevent that is to put anti-tamper seals on all of the panels. Like these <https://www.ebay.com/itm/30x-1-75-x-0-5-Inch-Chrome-Tamper-Evident-Warranty-Security-Labels-Seals-Skull/392977552918?hash=item5b7f499616:g:SA0AAOSwIe5fhPjQ>. They also make UV visible adhesives that can be applied to the screw heads to show if the screws in the covers and/or circuit boards have been removed.Regardless of what you show in your video, I think anyone that would spent this kind of money for something that it listed as "For parts" is an idiot and is just asking to get screwed! I dare say that all of the potentially interested buyers on Ebay feel the same way since no one has bought it in the three weeks that it's been listed.

content: I've seen this happen. Good luck with fleabay getting your stuff back.That's why 'no returns' and 'for parts'. Any volt-nut would send a messagefor more details. I have for almost all of the 3458s I've bought. If it'sa flipper, count on a bad A/D and other problems. The person that soldit to them had a reason not to want it any longer.
