Vintage Synth Repair

hi, i have a omni 2 with nothing powering exept the power on light. 
was wondering if i replace the tantulum 10uf caps on the power board 
can i use electrolytic caps of same value. does it matter if they are 
non-polarized. Would ceramic disk caps work or do i just need to keep 
looking for tantulum. i searched all previous posts but didn't find 
anything too specific. I am new to electronics and would appreciate 
any help. thanks
Ps should i go ahead and replace all the 10uf caps on all boards or 
start with the power supply board and hope that gets me somewhere.
