A good service manual with lots of info and a very fair price
;
Great value, good scan, just as expected, everything that you need.
;
Good scan, great price, but almost the same with the SV260 service manual.
;
This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.
 ;
This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.

SECTION I DESCRIPTION
The @ Model 739A Frequency Response Test Set simplifies frequency response determination by providing a convenient constant amplitude reference voltage of variable frequency. Frequency response of vacuum tube voltmeters, oscilloscope, video amplifiers and filters from 5 cps to 10 mc* can be quickly and easily checked. attenuator reduces the signal to an appropriate output level which appears a c f o s s 50 ohms a t the end of the special output cable supplied.
.30-IO MC
ATTEN. IOdb STEPS
The Frequency Response Test Set contains a wide range oscillator, special voltmeter and s t e p attenuator a s shown in Figure 1. The osciilator generates constant amplitude signals between 300 kc and 10 mc. The monitoring circuit is flat from 5 cps to 10 m c so that an external oscillator s u c h a s @ Model 200s can be used to reduce the lower frequency limit to as low a s 5 cps. Oscillator output is applied to the monitoring voltmeter, which samples the input to a stepattenuator. An arbitrary reference level is maintained on the monitoring meter as the frequency setting is varied. The
