Telefunken Opus 7 w/ Matching Powered Speaker

[jonboy55]

I just picked up a Telefunken Opus 7 with a matching powered speaker. I normally don't pick up German radios but the price was right - $25.00! Normally I work on antique radios (before 1950) or tube audio. I've never seen one of these with a blond cabinet and I've never seen a Telefunken floor model powered speaker. It's missing a knob. Please let me know if anyone has a lead on getting a knob. The speaker measures 28" H x 18" W x 12" D. Attached are some photos.
