Looking for a capacitor

[OHjim]

I am a newbie and an ME. I have a very miminum skill level in electronics and am looking for some guidance. I hope this is the right place. I have this amp: http://www.apexjr.com/Apexsenior.htm and the fuse blew on it the other day. So, I replaced the fuse and when I plugged it back in, there was a buzzing sound and then the top right cap blew it's lid off (see the second picture down on the apexjr page). I was trying to find the buzzing sound but could not in time, though it sounded like it could have been from the transformer .

The cap that blew is a Jun Fu 6800uf, 100V and is 30mm dia x 65 mm tall. I have not been able to find one like it. Can anyone point me in the right direction?

Would a cap cause the buzzing sound? If I put in a new cap, is it likely that the new one would blow as well? Is there anything else I should look for or test before going further?

Additional info: I have had the amp for 1.5 yrs, it has very little use, and I have "cranked it" maybe 5 times (house full of kids that are in bed when watching any movies). I never mounted the amp, just had it on the floor leaning against the wall (it was touching the cap that blew). Also, I had removed the ground pin on the plug due to something I read somewhere about hum but don't know if that affected anything. Thanks.

Thanks. Not sure they ship to the US or how much it would cost; I'll have to inquire. Would prefer a US supplier.
