HEWLETT-PACKARD 400D Vacuum Tube Voltmeter dB Meter Works well VTVM: $50
This HP 400D has been in weekly use on my audio test bench until removed last month. It's always worked flawlessly with no problems. The original power cord has been replaced with a 3-prong plug type. I have 2 copies of the Operating & Service Manual which are included. Due to this being vintage electronics, it's sold AS-IS with no warranty. Please examine the photos carefully and ask any questions before you offer. Meter will be well packed and shipped via FedEx promptly, US only.(Local pickup encouraged---cash sale)
