Sure... What I would do is bolt a tag + wire onto the tab of the old transistor (don't tell me you don't keep solder tags and small nuts/bolts (M3, 4-40 UNC, whatever) 'in stock' and get it running for the moment.

And also order a replacement transistor and resistors and fit them when they arrive. -tony
