you can replace capacitors very easly.. and they are pretty damn cheep to... just need some soldering skills...most capacitors dont "dry out" so i dont know why you say they were dryed out..the only capacitors that use liquid are oil based capacitors and those are high current capacitors, like hundereds of amps, much more current than any speaker amplifyer will ever see… most of the capacitors in home eletronics are made of aluminum foil and paper….
