A quick FYI: In our experience the biggest improvement in terms of sound quality comes not from re-capping (unless of course there's an issue with the caps) but re-chipping. Replacing the onboard 4558's used in the Janus preamp with really any decent modern op amp gives a much more clear, present and open sound to the preamp. In our Janus upgrade we install sockets so that op-amps can be interchanged. We typically use a Burr Brown OPA2134 but many many other op amps do quite well. If you're a bit uneasy desoldering op-amps, let us do it for you. We have professional desoldering stations and turn around for already working preamps needing upgrades is very quick.

If you’re ever thinking of recording your Rhodes with the Janus preamp - put in a better op-amp, it’s well worth the trouble.
