Up for auction The item is as stated. A Vintage Hewlett Packard Vacuum Tube Voltmeter Model 400A HP. It turns on and the needle moves. It is in good physical condition. IT powers on as you can see on pictures. this is the only testing done on it. Shows signs of age and the power cord in good condition overall great condition! Made in U.S.A. Volts 115/230. 50 1000 Cycles( Serial number F4378) Does not come with leads. Copied this from the internet. As you can see this unit is a very early serial number. Local pickup is free. Otherwise I will only ship FEDEX ground. Packed with TLC and a lot of bubble wrap. After repairing both a and a VTVM. I decided to tackle the oldest model of the series, the 400A. The 400A is the same size as the later 400C but uses all octal tubes and has an upper working limit of 1 MegaHertz. It's lowest level range ... moreis 0.03 volt full-scale. Its circuit consists of a 6SQ7 as cathode-follower input amp, two stages of 6AC7 amplifiers and a 6H6 as meter rectifier. Designed by David Packard in 1942, it is listed in the first HP catalog in 1943. When compared to the 400C and 400D models. It lacks external connections as a wide-band amplifier and does not use DC for amplifier filaments. DC is necessary in the other two models for their lower ranges(down to 1 millivolt) Like the other two models, the 400A power supply is voltage regulated. The 400A uses a 5Y3 rectifier, 0D3 regulator, 6SQ7 error amp, and 6V6 as pass tube. Repairs Before ever plugging in the 400A. I replaced the rotted power cord, a leaky 1 MFD capacitor, and the fuse holder for which the rivets had failed due to metal fatigue. After those repairs, I did a slow power up to reform the electrolytics. The meter went to full scale without any input. I pulled one side of the 0.1 MFD coupling cap between the two 6AC7 amp tubes. That allowed the meter to stay at zero. Although the original cap was a bit leaky, replacing it did not solve the problem. Even with the first 6AC7 pulled out, the meter still read fullscale. At this point, I s

Hewlett-Packard (HP) Model 3400A Analog, 10 Hz - 10 MHz True RMS Voltmeter
Hewlett-Packard(HP) Model 3400A Analog Voltmeter 10 Hz to 10 MHz True RMS Voltmeter 120 VAC. 12-Watts, 60Hz Operation Description: The Hewlett-Packard Model 3400A is a true root-mean-square(rms) voltmeter. Providing a meter indication proportional to the dc heating power of the input waveform. Six-decade frequency coverage makes the 3400A extremely flexible for all audio and most rf measurements and permits the measurement of broadband noise and fast-rise pulse. Pulses and other non-sinusoids with crest factors(the ration of peak to rms) up to 10:1 can be measured full scale. Crest factor is inversely proportional to meter deflection, permitting up to 100:1 crest facto at 10% of full scale. Features: 10 MHz bandwidth· High crest factor for accurate pulse measurments· Stable. Linear dc output· 1 mV full-scale sensitivity· ... more10 MΩ input impedance· Taut-band individually calibrated meter This HP Model 3400A meter is in excellent overall condition. Both physically and electrically. It has some very minor marks, barely noticeable. This meter has been used as an audio-frequency measurement instrument. The paint on the front panel is nearly flawless, and the control knobs and switch are in excellent, like-new condition. It hasn't been calibrated in some time, but the meter measures accurately on test voltages. All function ranges work well, and the meter itself is responsive. This is HP's"⅔" module. A polished-rail, cast-aluminum housing and baked enamel front panel. HP's chassis design was superb, and it protected the generally gold-plated circuit boards(most tropicalized for long-term durability) and premium components from flex movement, thus helping to insure the very long-term durability and reliability, tops in the electronics industry for many years. Hewlett-Packard instrument build-quality was rarely equaled- and never surpassed- in the electronics test-equipment industry worldwide. Many HP products exceeded mil-spec requirements for durability. This HP 3400A meter in
