    I am looking for a replacement for a transistor
    taken from a Pioneer receiver, 15W output, ≈30 yrs old.

    The transistor is marked: B507P EOL

    Seems to be paired with a D313P (marked: D313P EOK)

    Package type: TO-220

    I have attached a possible datasheet, although I am not
    sure if it is the same brand as I cannot find any identifiable
    brand marking. I do not have a schematic at this time.

    I assume I will need to replace both transistors of the pair.
    Maybe even replace both pairs.

    Prefer DIGIKEY, but any major distributor (<$51 minimum order) O.K.
    (I only mention this to avoid asking over and over. I appreciate any

    I could probably work with different pinout configuration as long as
    it is same package type.


    EDIT: #$&*$@&!, I meant to post in the GENERAL FORUM.

    nte153 = 2sb507p
    nte512 - 2sd313

    mcm, parts express, and Mouser also come up on the search page as NTE suppliers.

    Oops, I made a typo.
    nte152 is correct.

    Thanks guys.

    Comparing datasheets now.

    Just an FYI for anyone who stumbles
    across this thread searching for the same
    thing, the one I removed was shorted collector
    to emitter. Cause unknown at this time.

    Thanks again.
