I have a Technics PR900 and couldn't resist getting a PR804. The music store was closing up for business and got a good price. Anyway, I found out the PR804 will not load PR900 disks (I have a lot). The only way to get these to work is to find someone with the following: PR602, PR702 or PR902. The PR703 and PR903 will work, but was told the "2" series will work better. That person could load the PR900 technics format song files then resave as a PR902. Then the PR902 files will load into the PR804. If anyone is interested please let me know and maybe something can be worked out.

I'm not sure but maybe the PR900 files can load/save into a KN5000, then to the PR804. The instruction manual says KN6000 files and up will not load into the PR804, nothing about the KN5000...
Thanks, Anthony
