Oversized TO-3 TO3 like Yamaha 2SK77 and NEC 2D363 - Overview-II
Unfortunately the most of this BjT silicon types are developed for switching applications. But I think, some of this types are also for linear audio application. To determine this exactly the original data sheets are necessary.
Except Delco-GM all oversized TO-3's are made in Japan.
Two different oversized TO-3's you will find so as one normal TO-3 sketch drawing for compare.

You can also add the 2SJ27 to the list, it's the complementary to the 2SK77, also made by Yamaha, and never used in a commercial product.
Interesting. Unfortunately I don't find more exact information so as datasheet and images about google. Do you have a genuine Yamaha databook from those days?You can also add the 2SJ27 to the list, it's the complementary to the 2SK77, also made by Yamaha, and never used in a commercial product.
If not, perhaps you know the exactly title of such a book.
In this case please let me know about this thread:

Perhaps I can order this book for copies about my local library.
