Vintage Hewlett-Packard 140A Oscilloscope w/ Manuals Guaranteed Amperex 6DJ8 - $200 - (Milwaukee, WI)
Up for sale here is this vintage Hewlett-Packard 140A oscilloscope with 1402A Dual Trace Amplifier and 1421A Time Base and Delay Generator. It is complete and includes the power cord and all 3 manuals. It is guaranteed to work for you, though it may need calibration. It has all the tubes--1 GE 6AU6, 2 Mullard gold-pin 8233/E55L tubes, the oscilloscope tube, and 5 Amperex 6DJ8 tubes, one of which is marked PQ. I have not tested or swapped any of the tubes. This does have some wear but is in pretty nice condition overall. This does have the top and bottom covers--I just removed them to take pictures. It has handles on the front and sides as well. This was previously owned by Zenith, as shown by the plate on the back. Please see my pictures for details. US shipping and handling is $50. I accept Paypal. If you have any questions, please ask. I have other test equipment, collectibles, and other vintage electronics listed--feel free to take a look!
