I have the Valoy II manual in English as a digital file. I will try to send it to you as a pm but the file size may be too large.
I believe that the 1c came with the same ANR "filter" that fits over the condensor, AND a brass ring that had to be installed inside the condenseor housing. The brass ring raises the condensor the exact depth of the ANR "filter." ... I installed the brass ring in my Valoy II, but I wasn't sure I needed it because the condensor is seated under a spring inside the housing. The spring flexes enough to take up the difference of the ANR attachment / filter thing.
Hopefully that's somewhat clearer than mud. I will try to message you the Valoy II manual.
EDITED: I can't figure out how to message the attachment to you. Send me your email address and I'll send it.
