I have a vintage rc car and a nut fell off for the heat sink cause the transistor to burn out. I'm not sure if its all 4 or just the one
Theres 2 black and 2 green. I used a red light to focus the camera and you can see the bottom of the Green transistor looks toasty
I found 2sc3420 and its over 8 bucks for 1

Black:
T Y
C3420

Green

I'm wondering if that could be an A1357 instead, which would be a 2SA1357?

Seems like it could be reasonably complementary to the 2SC3420.

Now the thing is - do you want to try to keep it as original as possible, or do you just want it to run again?

The second one could be a 2SA1357. You didn't ask any question, do you want to find a replacement?

edit: sgt was faster. again.

Futurelec gives me $2,70 for the parts and$4 for shipping, to Canada, maybe it's cheaper in the US?
