Here's a post to embarrass Martin (Dillen).
After Martin helped me in the restoration of a white BM 2000 (bought faulty from a Danish small ad) I sent off my BM1200 (bought new circa 1972) for re-capping, new lights etc. It's just arrived back. I have still to test it fully, but I am amazed at how smoothly all the slide controls work and Martin has somehow re-finished the badly pitted/ corroded slide controls to look like new (even though not asked for). I know that Martin only does these repairs/ restorations as a hobby, and the postage costs to and from Denmark can be on the high side, but his services are well worth consideration if you feel that you don't want to tackle a B&O electronics restoration yourself.
Interestingly, with this last restoration, Martin discovered a badly installed major capacitor pre-dating the BM by at least 5 years. So much for the honesty of some main dealers selling repaired equipment as new (38 years ago, and long out of business.)
Thanks again to Martin.π
