 I'm trying to troubleshoot this tester due to erratic readings. I found the (Q7) voltage reading not right.
This transistor has a heat sink that pushes down on top of it. So it runs at least fairly warm. It is in a TO-18 package.
  It is staying cold to touch, any how the voltages called for on schematic are on the left. Mine on right.

Emitter   _-6.7v                                      Emitter -6.7v

Base    -7.4v                  My readings are: Base -7.4 v

Collector    -21.5v                                   Collector  -12v

above  readings were taken to ground with fluke DVM

 The collector voltage seems way low.

 The transistor has the # 3-009 on it. I'm trying to figure out what transistor equivalent to purchase.
It shows it being a PNP on the schematic, but the Mouser site has a 2n3009 as NPN.

 I'm confused   Here is what mouser shows available.

 Can someone advise me on which transistor I could use as a replacement? Thanks
 Here is the manual with schematic on page 45 and voltage chart on page 32.  all transistors on the tested within +/- 5% except the collector of Q7

Sorry I see the download of schematic did not work will try to get it up
