A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.
;
SCANNING OF HIGH QUALITY
VERY, VERY HIGH VELOCITY DOWNLOAD
VERY GOOD PRICE,
TRUE SATISFIED, THANKS

Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

I purchased a vintage Sony mixer off eBay and within the hour was able to locate and purchase the manual for it.I mean really,where else can you find a manual for a product made in 1983!? It was easy to find and purchase/download the manual I needed.I will use this site again for other equipment I have! Great site!

L A B O R A T O R Y I N S T R U M E N T S OF S P E E D A N D A C C U R A C Y
Standard -hp- instruments shown here are adaptable for making nearly every electronic measurement in the electronic field. Following is a brief description of a few o these instruf ments. Complete technical information will be sent- without obligation - on request. In addition, -hp- engineers are at your service to help solve special problems.
VACUUM TUBE VOLTMETER
-hp- Model 400A Vacuum Tube Voltmeter sets a MW standard of performance for voltage measurements in the audio, supersonic. and lower radio frequency region. Measurements up to 1 megacycle with this instrument are as simple as measurements with the usual multi-range meter a t d-c. Nine ranges give full-scale sensitivities from ,030t o 300 volts. Ordinarily no p r e cautions whatsoever are required: turn-over effect and waveform errors are minimized: there are no adjustments to make during operation: a large overload will not damage the instrument. The input impedance is I megohm so that most circuits will not be disturbed when their voltage is measured.
WIDE-BAND AMPLIFIER
-hp- 490A Amplifier is a new, versatile. wide-band amplifier designed for general laboratory or production use. I t provides exceptional stability a t 40 or 20 d b gain. and gives new freedom from spurious responses. ow phase shift is assured by a straight forward. reresistance-cou led amplifier design, together with inverse feed back. Frequency response is flat within 'z d b / between IO and 1,000,000 cps. Varying tube voltages or aging tubes have no appreciable effect o n the gain or other characteristics. When used in conjunction with -hp- 400A Vacuum Tube Voltmeter. i t increases voltmeter sensitivity 100 times.
AUDIO SIGNAL GENERATORS H-F VACUUM TUBE VOLTMETER
-hp- 410A. High Frequency Vacuum Tube Voltmeter combines in one instrument a n ac voltmeter covering frequencies from 20 cps to 700 mc. a dc voltmeter with 100 megohms input impedance. and an ohmeter capable of measuring resistances from .2 ohms to 500 megohms. The special probe places a capacity of 1.3 uufd acrose the circuit under test. Input resistance for ac measurements is 6 megohms. Six voltage ranges provide fullscale sensitivities from I to 300 volts.
-hp- Audio Signal Generators are designed for timesaving performance. They are excellent for laboratory applications because they supply a voltage as well as a known frequency a t the commonly used impedance levels. They are particularly suitable f o r gain measurements because no auxiliary a paratus
is required. They provide an excellent source of for distortion measurements because their waveform distortion is very small.

HARMONIC WAVE ANALYZER RESISTANCE-TUNED AUDIO OSCILLATORS
-hp- Resistance-Tuned Oscillators are suitable for almost every type of work. Their low distortion makes them particularlyvaluable in making distortion measurements on audio amplifiers. broadcast transmitters and other equipment. They provide a n excellent source of voltage for accurate bridge measurements. The output is suffcient to drive signal generators and other e q u i p ment requiring considerable power, Their wide frequency range also makes them suitable for work in the supersonic region. -hp- Model 300A Harmonic Wave Analyzer is a n excellent where accurate and laboratory and production work instrument for both rapid measurement of individual components of a complex wave is required. The maximum selectivity is sufficient for measurement of harmonics of frequencies as low as 30 cycles and i t can be varied 'over a wide range. With this variable selectivity feature. measurements a t higher frequencies can be made more rapidly. yet with no sacrifice in accuracy.
DISTORTION ANALYZER
This Model 330B Distortion Analyzer is -hp-'s newest. finest distortion measuring instrument. I t is capable of measuring distortion a t any frequency between 20 cps and 20,000 cps. It will make noise measurements of voltages as small as 100 microvolts. A linear r-f detector makes it possible to measure these characteristics directly from a modulated r-f carrier. The hi h sensitivity. ,stable accuracy and compactness of 330B ma e it extremely valuable for broadcast, laboratory and production measurements.
