Here is a vintage military I-777B DYNAMIC MUTUAL CONDUCTANCE Tube Tester, Signal Corps, early 50's era, not sure if this is a Hickok made model or not, I tested a few tubes in it and got mixed results so I'm not totally sure if everything is working properly or not, its' been sitting a long time and may need some switch cleaning, etc., it does power up and there is needle deflection, control panel is pretty clean and the unit shows light to average use, outer case has surface rust here and there, comes with power cord and manual, selling as-is, buyer pays $25 shipping in the lower 48.  Thanks!       TERMS:    Please FULLY read the listing, study the photos and understand and agree with terms before bidding.  If you do not agree with the terms you should not bid.  The photos are part of the description.  I mostly sell older, used items - expect them to show wear and have some flaws.  I try to give the best descriptions I can.  It's possible that some items may have unobservable or internal problems or damage that I'm not aware of.  I do not completely disassemble items for inspection.  If there is something that is important for YOU to know please ask before bidding/buying.  Items are generally sold as-is.  ZERO FEEDBACK BIDDERS/BUYERS:  If you have zero feedback please email me BEFORE bidding/buying to make sure we are on the same page in regards to how transactions work on Ebay and that you intend to follow thru and pay for the item promptly.  This is important!  PAYMENT:    I'm able to accept Paypal OR payment in-person upon local pickup.   SHIPPING:    Ebay requires me to ship to the address you have on file with Ebay, so that is the one I ship to.  Make sure the address is up to date and correct.  I am not responsible for the package if you have an outdated or incorrect address showing in the Order Details page.  Items usually ship out within 1-3 days but on bigger, bulkier, heavier items it may take a few extra days to ship as I drop those kinds of items off at a local pack/ship place. Shipping costs are mentioned in the listing.  I usually use USPS and FedEx. I avoid using UPS.   I try to charge as close as possible to actual costs.  THANKS!
