ANSWER: NO, I never obtained any manuals or schematics for any of the equipments below. Please check other websites, especially SAMS Photofacts or websites related to equipment manuals.

This Heathkit IT-22 capacitor tester checks capacitors for shorts and leakage, which is indicated through an eye tube.

This Heathkit IB-1103 frequency counter was probably from the 50s-60s and consists of eight nixies. The counter is capable of frequencies up to around 1GHz with 90% accuracy, depending on the frequency source. Although I have higher-ended and newer frequency counters, this is the first one I have ever owned that works despite its age.

I was given this simple HeathKit signal generator by a friend, it generates AF and RF frequencies for testing purposes.

This is a simple homemade power supply I made that generates variable AC, half-wave DC, or full-wave DC. It has a GFI outlet, a large isolation transformer, a heavy duty variac, and a few other small components.

This is the modified and better-looking version of the homemade AC/DC power supply, shown above. This time, it was designed to be mounted on a bench instead of the floor. I also never used the DC section very often it was omitted. Plus, a 0-250VAC meter was added to display the voltage on the GFI outlet. The case and front panel, which used to be an old audio signal generator, was repainted with dark hammer-finish gray paint.

This is a nice old resistance box for laboratory use. I'm not sure of its age, but it probably was made before the 1930s.

This is a CR Ratio-Bridge device by PACO. PACO is a division of Precision Apparatus Co.

This RCA signal generator came as a kit.

A neat and useful 9 tube RF generator that generates various test patterns for any analog TV. Most of the test patterns have a dark gray background with white bars arranged in different patterns, depending on the selection. Selections include vertical bars, horzional bars, crosshatch bars, and dots. The last selection generates color bars.

This Sencore RC-121 is a simple subsitutor used to temporarily subsitute components such as resistors, capacitors, and rectifiers.

The Superior Instruments 76 is a signal tracer and CR Bridge combination.

This is a early 1900s Weston direct-current (DC) voltmeter, model 1, and is made by the Weston Electrical Instrument Company. This voltmeter has two scales, 150V and 300V.
