If working on the 4 tube version of  this signal generator / tracer,  please note that terminals 6 and 7 in the schematic diagram are shown  crossed over for the 5687 pre-amplifier tube.  Pin  6  should  the cathode and 7 is the grid.  The tube pin voltage chart  also incorrect.   The same circuits  are used for the Accurate Instruments Model 153 and the schematic diagram for that is correct.
