Plus it seems to me that the Sanken T's would be much more reliable.

The Sanken is an MT-200 casing, and (I think) it's BCE pinout makes an awkward situation.

I have schematics of just about all the models (Thanks Enzo!

) But i have not yet worked on an older model that had the TO-3 cases.

Any info on how the T's are mounted on the heat sinks, etc.

I don't know if perhaps the board layout was redesigned.

Can you tell me in general, or specifically, how the Sanken's mount?

Also, have you bought any of those transistors within the US?

Its to small and cant take it if you use it at high volumes..
