dbx-3 service manual

Just acquired a TX-3 and wonder if you were able to find a schematic? Ed

Hate to resurrect old threads, but since their was no response posted I hope no one minds. 😀

I have an original TX-3 on the way and I'm also looking for a schematic/service manual. Would a NAD 4300 main board schematic be the same?

Thx.

Hi all
I, too, am in need of a service manual for this model. Any help would be great!

dbx tx-3 SM

Six years and no SM. Found bad transistor in muting logic in tx-3. Had FM working well but lost it when I started to try and fix the AM. Finally bought a second working TX-3 to use as schematic. Haven't finished this project -- put it aside to work on others. Bob F. in Yahoo FM tuner group had some suggestions about how to locate a schematic but not able to follow up. What is wrong with yours? Or do you just want to rebuild it? Maybe I can help.

Problem holding stations.

Problem holding presets/memory.

Sounds great when it works.
