1974 Brain Box saves the day.
Those seem to be some of the worst ones, the ones with the Tall Standing "Top Hat" empty transistor case with the long fine thread machine screws holding it on. Also they have the single layer gold heat sinks too, those are the cheep built ones.
I am looking for this style pictured below, with the shorter wider Top Hat working transistor, held in by short course threaded screws, and the thermally conductive insulating thin sheet between the the 2 pieces of the 2 part gold heat sink. Better yet if the Top Hat transistor has the manufacture's printing on the top of them, that tells you that it is a real working transistor and not a fake one like the taller narrower ones. These are the better ones if you can actually find them.
Have been able to find this style in the New Old Stock that is out there also.
