Items From My Collection of
Vintage and Antique Test Equipment and Tube Testers
from the 1920's, 30's, and 40's

Some items shown below are only one of that manufacturer's items in my collection. See the following pages for more items from a particular manufacturer:

4 Pin Tube Tester Antique 4 Pin Tube Tester
Here is an very early Montgomery Ward tube tester model 5156 that only tests 4 pin tubes from the 20s. (Let me know if you have any info on it) This tester plugs into the tube socket in the radio and the tube under test plugs into the tester. The meter can be moved from the "A" position to the "B" position to test the plate and the grid side of the tube.

EVEREADY meter Antique Eveready Radio Battery Meter
This is a radio battery tester from the early 1900's. It is about the size and style of a pocket watch. It was used to check the current level (0-35 Amperes) in the batteries of 1920's radios. This meter is marked on the face with "EVEREADY" and a patent date of Aug. 9, 1910. It was manufactured by the American Ever Ready Co. This meter is in excellent working condition and makes a great addition to my radio collection.

DC Polarity-Indicator Antique DC Polarity-Indicator
I never saw or heard of these until I found this one. It was patented in 1905 and shows polarity in a DC circuit using a liquid in a glass tube that when current is passed through it, the negative end "Glows". It has a patent date stamped on it of Oct. 25, 1905. It was available in two models, a model 3220 for battery circuits and a model 3221 for 50-600 volts. They use a liquid filled glass tube that is incased in a hard rubber type case with a connector on each end. Electrodes inside the glass tube attach to the connectors. The metal sleeve can be rotated to cover the glass windows when carried in your pocket. Manufactured by the Manhattan Electrical Supply Company (MESCO), Jersey City NJ.

Hickok Model 47 Early Hickok
Volt/Ohm/Capacity Meter

This early Hickok meter is AC powered. There is no model number on the faceplate or the case. It has Model 47 printed on the face of one meter. It measurers resistance, capacitance, and voltage. It uses an original Sylvania SX-171-A Power Amplifier 4 pin vacuum tube. From the construction I'd place it in the late 1920's.

Hickok SG-4700 ? Early Hickok Tube Tester - SG-4700 ?
This early 5 meter Hickok tube tester is battery powered and requires both A and B batteries to perform tube testing. There is no model number on the faceplate or the case. It is similar to the reportedly first commercial Hickok tube tester, the five meter SG-4600 manufactured in the 1920s but this tester only has two tube sockets and a different faceplate layout. The SG-4600 testers I have seen have three tube sockets.
