If you can figure out the size, mouser probably has it

The blown capacitor is at location C59 on the board.
What is the model & Version # of your board?
I may be able to find some board schematics that will help into pinpointing exactly what goes there.

                                                   OR


Some member can take a look at their good board
and tell us the numbers labeled on the component?

Looks like a 3902 board.

I should add that to blow a cap up in that manner would indicate a short in the circuit, you may have more than just a cap problem. AC voltage will take a cap out that way pretty quick also.

That looks like 273 which should be 0.027 uF

If the hum is the only problem, you can probably just try different values as it's probably not that critical to be exactly the same. You can easily solder a non-surface mount cap on there. Radio Shack sells a 'grab bag' of caps for a few bucks.

It's a filter cap on the input side of a +5vdc regulator for the audio.  I had one fry on one of mine once too.  The manual specifies a 16v part, but 25v would probably be better.  Mouser.com p/n for a 16v replacement is: 80-T499B475K16TE6K0.

The parts diagram calls it out as :  C59,69 CAPACITOR, 4.7UF, 10%, 16V, TANT, 3528, T/R

Here's a page from the 3902 schematics.  The cap is circled in red.

Hope it helps.

That's a very common value. Again, something RS should have. It doesn't have to be surface mount, and why pay shipping for a $1 part.

It's pretty common for those caps to short out and burn... just like the drop shaped tantalum caps with the 2 wires soldered in...
