NuTone IMA3303 desoldered transistor leads

The red arrows are pointing to 2 of the 3 leads from one of the amplifier output transistors.  These 2 solder joints have failed due to long term heat exposure.  

Basically the transistors has only 1 lead soldered.  If you look carefully, you can see the crack in the solder joint, around the component lead.
