Power Transistor identification

[Paulmongan]

Hi Folks,

I have a power transistor labeled EWM 44 RCA H8336.
Can anyone help me find this part? Is there a translate table available to use? I did a google search but had no luck at all.

Hope some can help.

Kind Regards,

Paul

H8336 is 1983, week 36, almost certainly. Most of the other transistors have 1984 datecodes which backs this up. Datecodes are
YYWW.

Its possibly an OEM part from RCA - I'd trust the board legend of "2N3055" for replacing it.
