Hey everyone,
I'm repairing a Bose 1800 series amplifier and am looking to source a replacement for this transistor.
its a Motorola MPS-U10. Bose used it due to RCA discontinuing the 2N6175 back in the day.
I was hoping someone here could recommend me a replacement.
I was looking at mouser and here's what I found thats comparable:
2SC4793 (Seems ideal)

2N5655 (Maybe a bit slow?)

2STC5949 (Maybe excessive?)
http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00171942.pdf
BU406 (Also a bit slow?)
BU406 Fairchild Semiconductor Bipolar Power
The pin out on the U10 is EBC, I dont think any of the ones I found are in the same pattern. The U10 attaches to the main heatsink.
Thanks!

Yes this is Q3. I figured I'd be stuck having to bend leads around. Probably will have to find something to extend them as well.
What were your thoughts on the 2SC4793? I came across the MJE340 in an earlier search. Should have mentioned it as well. I was leaning towards the 4793 because of the higher collector current and high Ft. Most of the others were well below the U10. Originally I dismissed the 4793 because it was only 2W however I opened the datasheet and w/ heatsink it can handle 20W.
They dont seem to mention the MJE's Ft in the datasheet.

MPSU10 Transistors
Hello Audiohead. Do you have any more of those MPSU10 transistors? I need a pair to fix the horizontal deflection circuit in a Heathkit AD-1013 Audio 'scope.

I think I have some MPS-U10, How many do you need?
I look for them, if I manage to find them I can send it to you for free.
Please email me your address.
