Plug it in, turn it on, and see if it works. But stay near it and see if anything starts to smell. Mine started to smell, then smoke (no fire, luckily.) I put in on the bench, opened it up, and identified the bad cap. It was pretty obvious. I replaced all three of the same type and the machine now works fine.
BUT ... the same thing happened to my A700 and now have to deal with that baby.
I'll post again with more details on which caps to replace.

In 1974, when the A700 was brand new, I had an opportunity to use one for a few weeks. I didn't like it, mainly because of the somewhat 'flimsy' construction of the controls.
Just my opinion.
:)
flimsy controls is an understatement. all of the slide control handles on mine have broken off. not a good design. but the machine has performed well and generally sounds good. i bought mine for $15 at a local thrift shop. it came with an RCA 2-track classical tape that i sold for $30.
To be more precise, the problem caps are C113, C113 and C115 on the tape drive control board. These are 0.47uF 150 V metalized paper caps. I substituted 400 V which worked fine.
