Superior s New MODEL 77

VACUUMT BE V TMETER

WITH NEW 6" FULL-YIEW METER

Compare it to any peak-to-peak V. T. V. M.

madę by any other manufacturer at any price!

^ Model 77 completely wired and calibrated with o/ł accosories (including even porfable carrying cate) *ell» for only $42.50.

J Model 77 employt o ssnsitiy* six inch meter. Extra large meter scal* enables us to print all calibrations in large eo»y-to-rsad type.

tj Model 77 uses new improved SICO printed circuitry.

^ Model 77 employs a 12AU7 as D.C. omplifier and twa 9006's os peak-to-peak voltage rectifiers to ossure maximum stability.

^ Model 77 uses a selenium-rectified power supply resulting in less heot and thus reducing possibility of domoge or value changes of delicate components.

^ Model 77 meter is virtuolly burn-out proof. The sensitive 400 microampere meter is isolated from the measuring Circuit by o balonced push-pull amplifier.

^ Model 77 uses selected 1% zero temperaturo coefficient resistors os multipliers. This assures unchanging occurate readings on all ranges.

VAS A DC YOLT.METER: The Model 77 will measure any voltage up to 1500 volts with negligible loadlng. It 18 Indispensable ln recelver and Hl-Pl Ampllfler servlclng and a must for Black and Whlte and Color TV Recelver servlclng where Circuit loadlng cannot be tolerated. A speclal feature per-mlts accurate zero center measurements necessary for the true allgnment of Foster-Seely (Armstrong) FM detectors. Ratio Detectors and the newer Gated Beam Detectors.

J AS AN AC VOLTMETER: The old-fashloned laboratory AC V.T.V.M. ^v was cumbersome. erratlc and requlred several dlal manipulatlons to arrlve at a readlng. The Model 77 when connected to a Circuit will qulckly and slmply measure lts RM5 value If sine wave. and Its peak-to-peak value If complex wave. Pedestal eoltages that determlne the ••black^,, level in TV recelvers. sync. pulses and saw tooth voltages are easlly read with the Model 77.

J AS AN ELECTRONIC OHM.METER: Because of lts wlde rangę of meas-w urement ln the reslstance rangę (from .2 ohms to 1.000 megohzns) the Model 77 will be your most rrequently used reslstance meter. Loaky capacltors whlch may not show up on other resistance meters. show up glaringly when tested with the new model 77. Because of lts aensl-tivlty and Iow loadlng. intermlttents are morę easlly found, isolated and repalred.
