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. 

To thank the Author because you find the post helpful or well done.
