6 months ago I bought a pair of Braun L 630 3-way speakers on ebay. It's taken me until this week to get to getting them re-conditioned.
Before getting into the speakers I'm going to share the service manual for future reference. Yes. There is a service manual for Braun speakers. It's main value is a schematic and a parts list that shows all of the driver part numbers and crossover component values.
The manual that I bought on ebay was in itself a scan and fairly faint. When I scanned it I reduced the brightness and raised the contrast and it improved a bit but it's still fairly light but readable. The manual actually covers models L 530, L 530F, L 630, L 730 and L 830. I'm posting the 3 pages for the 630 here but if there is interest in the other modely I'll scan them for anyone that wants them.
The manual is in German. I'll do some translations of the important stuff in the next post.

edit: I rescanned the pages, a little less brightness, a little more contrast and sharpness. And zipped them to make it easier to dl and print.
