Areyou looking for a quick, easy, inexpensivetest instrument with which to DYNAMICALLY TEST every radio receiver?  Do you find the need of a simple,rapid, low-cost tester to find the "tough" ones for you?  Are you anxious to stop those wasted,profitless hours of aimless hunting for elusive "bugs" in yourcustomer's sets?

Ifso, you will welcome the newest in reasonably priced dynamic test equipment--

The SUPREME AUDOLYZER. This instrument will give you a completediagnosis of any receiver by using the Signal Tracing method ofdynamic test.

EASE OF OPERATION!

Youwill be surprised and delighted at how easy it is to operate the SUPREMEAUDOLYZER because it requires but one probe at a time and you always HEAR THEDEMOLULATED SIGNAL rather than look for its result on a magic eye or meter.

Hereare but a few of the many things you can do with this amazing instrument! Youcan find the dead portion of any receiver by connecting your modulated signalgenerator to the receiver and touching the SUPREME AUDOLYZER'S probe first tothe antenna post, then the grid of the R.F. tube, the plate of the R.F. tube,etc., right back through the complete receiver. You will hear a signal in theAUDOLYZER'S speaker (which has a volume control) until you hit the dead stage.No signal means a defective stage.

VACUUM TUBE VOLTMETER!

Thenyou use the AUDOLYZER'S vacuum tube volt-meter to determine whether all the DV voltages are correct without disturbing the normal operation of the receiver! This meter has 7 rangesof 0/1/3/10/30/100/300/1000 DC volts at 15 megs input. The meter is a center-reading type with"minus" voltages indicating to one side of center scale and"plus" voltages to the other side. This eliminates the necessity ofyour shifting test leads for polarity change.

Next,you can check the receiver's oscillator by connecting the probe to the setoscillator's output and watching the meter. If the oscillator cuts out or isweak over any portion of its range, this immediately shows up as a change inthe AUDOLYZER meter's indication.

Manysets have oscillator trouble where the coil changes inductance. Sometimes thischanges the resulting variable frequency band sufficiently to not allow theoscillator trimmer and padder condensers to pull the oscillator into line for apredetermined I.F.

CHECK FREQUENCY

To determine the unknown frequency to which any receiver circuit is tuned--oscillator, I.F., orR.F., just use the tuning portion of the SUPREME AUDOLYZER in connection withit V.T.V.M. as a frequency meter. For the receiver's oscillator, place theAUDOLYZER probe on the oscillator output and tune the AUDOLYZER for the outputand tune the AUDOLYZER for the greatest swing of the meter. Then read thefrequency on the AUDOLYZER'S direct-reading dial. For R.F. determination,connect you signal generator to the receiver's input and place the AUDOLYZERprobe on the output of the R.F. stage under test. Adjust the signal generatorand AUDOLYZER to the same frequency. Then adjust the receiver dial for maximumawing of the AUDOLYZER'S meter needle. Finally, adjust receiver trimmer untilreceiver dial reads correctly. To determine the actual signal being fed theI.F. stages connect the probe of the AUDOLYZER dial until you get maximum swingof the meter needle. Read the actual I.F. signal's frequency on the AUDOLYZER DIAL! In none of these tests is thereceiver de-tuned by the application of the probe.

GAIN MEASUREMENTS

Bymoving the AUDOLYZER probe from stage to stage of a receiver and noting theAUDOLYZER meter's voltage reading in each case, you can readily determinewhether a stage, a tube or a transformer results in a gain or lossof signal strength. Thus, you can make relative gain measurements with your SUPREME AUDOLYZER.

Youcan check the A.V.C. circuit for correct applied voltage under actual operatingconditions because you have a Vacuum Tube Voltmeter in the AUDOLYZER whichinstantly indicates this voltage at any place in the set--and its variationunder different applied signals--without upsetting the correct operation of theset. You can adjust A.F.C. circuits in the same manner.

LOCATE DISTORTION

Distortioncan easily be noted by ear. Most distortion occurs in the second detector oraudio output stages. By placing the probe at any place where the audio signalis normally present, you can hear thesignal and instantly determine where the distortion originates. This is alsotrue of any R.F. or I.F. stage if you have a scope, you can connect it to theAUDOLYZER and see thedemodulated audio signal as well.

Leaky,shorted or open condensers can quickly be found without unsoldering them fromthe circuit. Because the SUPREME AUDOLYZER can be electrically divided into twosections, you can use two probes at atime for checking intermittents, working from the second detector's input andoutput toward the antenna and loudspeaker or vice versa. The AUDOLYZER can beused to check antenna efficiency as it is a fine field strength meter. You cancheck high impedance pickups, microphones and other input devices. You can makedozens of other tests with the SUPREME AUDOLYZER which will astound you bytheir rapidity, simplicity, and their ability to find the trouble in the shortest time. You can check the receiver's loudspeaker againstthat in the AUDOLYZER for distortion.
