Cracked my Crack - Question.

[John EH]

I mounted a Raspberry Pi and HiFiBerry DAC under the hood years ago in my Crack, all was well.  I upgraded to the DAC + Pro they offer and needed to put right angle connectors on the RCA's under the hood.

Well, I slipped and I whacked a big heat sink  on the Speedball and then powered up and noticed the two LED's in front of the heat sink weren't powering on.  Disassembled and seems I physically broke the TIP-50.  The metal separated from the plastic.

Is this a good replacement part?  (already ordered some)

Stupid.  But my soldering skills are still awesome.  Removed the TIP-50 with no problems on the board.  Just need to slap a new one in I think.

Whacking that TIP-50 and breaking it would make the LED's not come on, right?

That TIP50G should work OK.  With a broken transistor, it's difficult to say what else in the circuit could be damaged without replacing the transistor first.

If the LEDs are out the 2N2222A could be shorted too. Might be worth checking it.

Got it.  It was just the TIP-50 as I suspected.  Got some from Digi-Key and every sweet little LED lit up just fine.  Sounds great.  I have 2 Cracks at home and both are amazing.

Just for fun here's the old girl.
