Vintage Hewlett Packard Vacuum HP Tube Voltmeter - HP 400DR I have plugged it in and it powered up. The light came on and the needle moved. That is as far as I have tested it. I am not familiar with these so I'm not quite sure how it works. This may work perfectly or it may need fine tuning. I'm really not sure.The case has some wear and surface rust.Thank you for looking and feel free to ask any questions!
Condition Used :
An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections.
