  1. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

    Show us a picture of the cards?

    seems unusual for both sides to fail at the same time. Or is there a story to tell?

    Very unwise to post a personal email on an open forum.

    Start a conversation with a member instead - click a member's avatar and a box appears with "start a conversation" option.

    You won't get any info whatsoever from Unison. The UK importers also are under instruction to not provide schematics or servicing info. I had a very rare £8K Unison power amp in for repair and after trying everything, including shout outs on DIY audio etc etc, I had to go in and work it all out for myself.
    Any/all inquiries with factory or importers will just get "return the amp to us for servicing" IME.
