Just be careful of the pinouts. The Tektronix TO-127 parts are ECB
while the TO-220AB and TO-247 parts listed above are BCE. I have not
done a serious search for a modern high power part with the same
pinout or TO-3 parts (for high power compartments?).

Also watch out that you use a proper insulator for the mounting hole. The Tek transistors had molded plastic to insulate from the mounting stud.
