DIY Counterpoint SA12 Repair...does it make sense to spend the $$?

Have an SA 12 and SA 3.1... running Vandersteen 2Bs. I'm the original owner - gear was bought in Leucadia, CA in the late 80's. The SA 12 just blew a cap (?)... flexible silicone like substance all over the the c-board. Pre-amp is still OK. Living overseas so practically impossible to ship stateside for professional repair. Question: does it make sense to spend the time and $$ on this "project". I have access to local techs that can do basic electronic repairs but have to wonder at the complexity of this DIY job. Advice??
