Note that the R-1034A Test Set and the R-1034B Control Line Test Set are two very different products inside despite the fact that they have a similar purpose.
Many dispatch systems had the base station or repeater at one location and the control point at another. Setting up or maintaining the connecting phone line required the ability to make both DC and AC measurements. Motorola and Triplett together designed the Model R-1034A Control Line Test Set, and the mixed background of the Motorola 2-way engineers and the telephone telecommunications background of the Triplett engineers shows in the design. This unit is essentially a specialized AC and DC VOM and an audio generator all in one ruggedized package (they used the existing housing from the Triplett 630 series VOM). It measures telephone line current, telephone line noise, DC resistance and both AC and DC Volts, and all measurements are using ranges that are optimized to telco control lines. This test set will also send audio tones at an adjustable level and measure received tones in dB on the meter. A pushbutton adds a 10dB attenuator in line   A switch on the lower left of the panel selects bridged or terminated mode. The unit was built into a sturdy protective carrying case with a pocket in the lid for the book and the probes, and a snap-hook shoulder strap for carrying. There is a 1 amp fast-blow fuse that is in line with the volts and ohms measuring circuitry inside the battery compartment. The test set is powered by two common 9 Volt batteries and one D cell battery - and the second 9 V battery is behind the "D" cell!   Before you buy a second-hand R1034 make sure that you open it up and check for corrosion caused by leaky batteries (this is the voice of experience speaking...).
Model R-1034B Control Line Test Set Manual   511 kB PDF file   6880310B60-O
Note that the R-1034A Test Set and the R-1034B Control Line Test Set are two very different products inside despite the fact that they have a similar purpose.
This is a redesigned and updated version of the above. Triplett sold this unit as the "Model 4 Subscriber Loop Test Set" for doing telephone circuits.
Unfortunately, the manual for the "B" unit does not contain a schematic diagram or parts list. If anyone can turn up that info - even if it is the Triplett manual - we'd appreciate it.

S1051C and S1053C Manual   2.9 MB PDF   6881021A05-C
This is an AC voltmeter that covers 1 millivolt (-72db) to 300 volts (+52db) in 12 ranges, and is +/- 2% from 50 Hz to 300 kHz, or +/-3% from 20 Hz to 1 MHz.
The S1051 is battery operated only and used a single 8.4 mercury battery (Mallory TR-136), which is no longer available. It works just fine with a standard 9 volt battery with a 470 ohm resistor in series with it. The S1053 series is AC or Battery operated, the AC adaptor provides 9 volts AC. It's easy to convert an S1051 into an S1053 by adding a leftover 9v DC wall wart and the missing components (the "C" version manual covers both units).
The SKN6001A is the "official" test lead kit that is used on several Moto measuring devices. It is a 30 inch length of RG-58-style shielded cable with a standard 2-pin bannana plug on one end and a pair of insulated alligator clips on the other.
S1067 Transistorized Audio Oscillator Manual   4.6 MB PDF
The manual calls for a no-longer-available 22.5 volt Burgess battery. An Eveready 763 (NEDA 710 or HS6571) battery works fine.

It's the same as the Boonton 92E click here for a photo, because the S1339A was just a relabeled Boonton.
T-1034 RF Signal Generator   Schematic     External photo     Internal photo
All our source had was the pullout schematic - he's still looking for the rest of the manual... If anybody has it, let us know.
The T-1034 RF generator is a relabeled Measurements Corp. Model 80 generator. The original Model 80 (1944 vintage) ran from 2 MHz and went up to 400Mhz and were built by various companies under military contract under the designation TS-497A and TS-497B. The later 80-R model dropped the 2-5 Mhz lowest frequency band and replaced it with a new 400-475 Mhz highest frequency band (the mechanical design limits the number of frequency bands). The basic RF design relies on a 955 acorn triode connected as Colpitts oscillator. The 955 tube sits in a round silvered can (visible in the internal photo) surrounded by the various oscillator coils, which rotate into position with the band switching knob. The mechanical internals are beautifully laid out and a fine piece of precision work rivialling a good watch. Because the oscillator delivers the output power too, modulation is limited to 30% and is AM only - but there is enough FM in the output to be usable. Output power is induction coupled to a variable attenuator. The 80-R was built through the 1960s.
Technical Manual TM 11-5030A (3.9 MB) is for the for the TS-497B/URR military version of the Model 80. There are enough differences that we'd like to have the regular manual also. As far as military manuals go, if anyone has a copy of the later TM 11-6625-253-12P we'd like to get a copy.
SLN6221 Tone Generator   Photo     Manual (294 KB PDF)     Smaller file (203 KB PDF)
This is a reed-based test tone generator designed to plug into a service monitor. The upper socket is for the small reeds, the lower socket for the "copper banana" reeds. 6881114A02-B
SLN6222A and SLN6222B Reed Tester   Photo     Manual   587 KB PDF
This unit uses a no-longer-available 6.5-7 volt 1000 mAh mercury battery that is 0.662" diameter and 3.245" long. The battery may be one of the following brands and types: Eveready E135, Mallory TR-135, or Ray-O-Vac T-135. If you have one of these you may end up using an external battery pack or a DC wall-wart style power supply. There is enough room inside the case that you could add a 6v three-terminal regulator with one silcon diode to raise it 3/4 volt (which would deliver 6.75 volts), then power it with a 12vDC source. 6881114A04-D
