Yes, Triplett instruments were pretty good. Often when working on old radios and equipment the 1000 ohms/volt and 5000 ohms/volt are required.

The problem with restoring an older sig gen is verifying frequency, wave-form amplitude, and waveform "cleanliness," or lack of distortion.

Even with a calibrated sig gen, it is a good idea to verify output frequency and if necessary amplitude with external test equipment when doing an alignment or other tasks...
