Already ahead of you there. I actually still have the printed manual I got when I bought the amp and I did download a PDF of it too.
A high school friend of mine had a JX30B that we added a HF horn to use for his keyboard amp. Indeed all the variants are likely very similar. If I can't find the actual manual I'm sure I can just inspect and markup the JX30 manual which is likely quite similar.
I saw on another thread where the OP was looking looking for a JX25 manual that he stated he had found one for the JX20, so they must be out there. Funny I can't dig it up with the search engines.
