I checked the voltages of the transistors and found some anomalies. Most were in the range of 0.46v to 0.73v. TR5: 0.12v, TR13: 0.17, TR11: 6.68v, TR 9 fluctuated between 0.19v and 1.86v. Some were reading positive voltages and some were negative voltages. I pulled out TR11 and measured it on my meter- see the attached photo.
