looks to be in good shape. that brown at the base of the big caps is glue... Keiga made that amp, and on all their amps, they used that glue on everything, even the wire connectors. it is extremely tough glue, and is very effective anti-vibration. but usually the caps on these amps bulge before they leak. i have also seen the amps start to make noise before the caps start to go... so, keep an eye... er... ear out for any strange sound the sub starts to make. you want to catch it and fix it before it causes damage, that may not be repairable due to the lack of parts available for these.
but, it is getting to that age where you should take a look at those caps every few months. with all of the China made parts that the amp companies are using, the capacitors are of extremely low quality, and not expected to last a long time.
the oldest electronics in my shop is the shop stereo... it is a mid-line Pioneer receiver that i bought brand new in 1977. never worked on, and gets played almost every day for the last 37 years... nothing late model that i have worked on is going to be able to do that, and that includes just about every home and car audio amp made in the last 10 years that i have worked on.
gone are the days of a inexpensive amp lasting 20+ years... in fact, even a lot of fairly expensive amps these days do not last like amps used to.
