dbx 20/20 Equalizer Schematics
I found schematic drawings for the dbx 20/20 Equalizer. An ebay seller was selling a partially working 20/20 and I noticed his description said the sale included a copy of the schematics. I contacted the seller about getting a copy of the schematics and he generously sent me a copy. There were fourteen 11 x 17 pages. A few of them have some parts that aren't legible but it looks like there is enough there to be useful (especially when previously there was nothing).
I have been searching for technical data on the 20/20 for a long time. I even contacted a couple of service centers that had supposedly worked on these units in the past. Both told me the same thing: no service manual was available and they didn't really want to work on them. Now these schematics appear. I guess dbx never published an actual service manual and expected buyers would send the units back to dbx? Now of course the new dbx company doesn't support the vintage products.
I have scanned the fourteen 11 x 17 pages into a PDF file and have it available to upload it here for anyone else that has a dbx 20/20 they are trying to fix. The PDF file size is 5,165KB (5MB) so it is quite a bit over the maximum PDF file size allowed here. Any suggestions?
