Rheinberg illumination on a Jenaval

[Klaus Yde]

Can anyone help me with this. I have a complete set of filters http://www.mikroskopie.de/mikforum/read.php?1,23496,23496#msg-23496 that worked perfect on my Laboval - but not on my Jenaval - I have tried in in a filter slide in the condenser, on the bottomplate, in the the filter wheel but to no result whatsoever.

Is there a special trick or dont it work with oo objectives?

Many kind regards
