The bases of TR6 and TR7 are connected together through the seondary winding of T1, so they should both have the same voltage (0.2V) on them. Check your soldering of T1 and TR6 base carefully.

The readings on the collectors and emitters of TR6 and TR7 indicate that the primary winding and one of the secondary windings of T2 is OK.
