I want to use just the power section of my Jolida 502b and use a separate pre-amp to drive it.  How difficult is this to do?  I have asked this question around various boards before I realized that Response Audio has a presence here.  This is clearly the best place to ask the question because of the relationship between Jolida and Response Audio.

Hello Zoe,
   Using the Jolida 302/502 as a power amp is very easy. I have two of the SE models running this way for biamping with a custom preamp.  Are you looking to do this yourself or looking to send it in?
  If you want to do this yourself, please PM me and we can go through that rooute. I do not want to publicly post that procedure as we take no responsibility of someone attemping something they are not truly capable of.
