Up for auction in CD-ROM format is a book entitled “SERVICINGRADIO ANT TELEVISION WITH A VACUUM TUBE VOLTMETER”. This 48-page bookin Adobe Acrobat .pdf format is designed to help you obtain a thoroughunderstanding of one of the primary tools in electronics, the VTVM. The text ofthis book assumes no previous understanding of electronic theory on your part.It is written to provide you with a great deal of useful information concerningvintage radio servicing with an os...cilloscope, regardless of your background, whether you are still a beginner or a person experienced in electronics.From the book...PREFACEThe versatility of the modernall-purpose vacuum-tube voltmeter is so extensive that a group of separatemeters would be needed to replace it. The universal vacuum-tube voltmeter offers the service technicianmaximum single-instrument utility. Inthe one instrument are combined the separate functions of high-resistance dcvoltmeter, high-impedance ac voltmeter, wide-range rf voltmeter, wide-rangeohmmeter, and dc Milliammeter.This book describes applications ofthe universal vacuum-tube voltmeter-ohmmeter in radio and television servicingand miscellaneous experimental work. Space has not permitted inclusion of allpossible applications, since there are many. We have made a selection of tried and proven procedures and offer themwith the sincere hope that they will lighten the ever-increasing burden of theradio and television service technician.TABLEOF CONTENTSCHAPTER I – THE VACUUM-TUBEVOLTMETER1.1 Diode Type1.2 Triode Type1.4 Zero Setting1.5 Range Switching1.6 Balanced Triode Pushpull Circuit1.7 Modes of Operation of TriodeVacuum-Tube Voltmeters1.8 Rectifier-Amplifier Instrument1.9 Vacuum-Tube Ohmmeter1.10 Advantages of the ModernVacuum-Tube Voltmeter1.11 The Sylvania Polymeter Type221Z1.12 Rules for Use of theVacuum-Tube Test Meter
