I picked up this amp and got it home and it wouldnt turn on. So I opened it up and see that one cap is blow and the 2 large ones look to be bulging. Need some help on where to start. I took a couple pics.

Not likely but it can't be fully repaired without having that cap replaced.
I don't have any specific information on this amp but if no one else can offer suggestions, post the DC voltage on the LM339 and the TLx94 and I'll see if something looks wrong. Have both B+, remote and ground connected. Copy and paste the following into your reply.

Those look like temperature rating, some kind of manufacturing code and maybe manufacturing date (week 23 of 2017?) but we actually need the capacitance value, say 4700 or 10000 microfarads (uF) or something similar, and a voltage rating, say 25V or 40V or whatever.I found the outside of the cap in the amp. I can read on one side

Dose that tell you what cap it can be?
Even better, post pictures of any inscription printed on the plastic sleeve.
They replied back saying that it is a MAE005, 0.47MFD 50V electrolytic capacitor.
Would this be a good replacement:
