That 380s is to this day still an outstanding pre-amp. I would definitely keep it. I would have it checked out to see if it is operating within spec, but, it is definitely a keeper.
As for the amp, unless you have in your possession or heard in your system an amp that outperforms that amp, I would get it repaired and replace the caps.
