[sdiy] Reasonable cap replacement policy

[John Speth]

Hi folks-

Today I called a shop about replacing the belts on my 30 year old 
cassette tape deck (Fostex X-26). The guy quickly recommended also 
replacing the caps (I assume just the electrolytics). I'm guarded 
against folks who do repairs on stuff that don't show signs of need, 
which my tape deck doesn't.

What are the prevailing opinions on replacing old electrolytics in 
equipment from the 1980's?

I hope I didn't start an opinion war.

Thanks - JJS
