PCB files contributed for redesigned Sansui 9090DB F-2655 Dolby board

Hello!
A friend restoring his 9090DB asked me if I could convert the Dolby board into CAD so a new one could be ordered. The idea was this would replace the aging board with one that doesn't need repinning.

It was a fun project that resulted in a nearly identical reproduction of the original. A couple of improvements were made, such as moving the caps and resistors tacked to the back to be on the top side, with their own holes.

Unfortunately, he shelved the restoration indefinitely over a year ago after ordering the boards, so I have not had any feedback. Not wanting my efforts to go to waste, I'd be happy to share the schem/PCB if anyone is interested. I have checked it six ways to Sunday, so I'm not concerned about its integrity, but I would ask anyone interested to do a sanity check.

Very nice! If you want to contribute the PCB files, you could send them to the AK database.
 
Do you have the Gerber files or just the boards? I have a 9090DB in the queue but will not get to it for a while. I am interested.

Be happy to! I've created a zip with Gerbers, engineering notes and KICAD files, but I am unable to register/login at AKDatabase.

Are you guys making a database for PCBs?

Already created! Hopefully you will be able to access it soon from the database here.

This is great! You should put them on eBay so more people have this option. It's the first place I look for stuff like this.

Although I'd pay big money for a board that just removes all Dolby functions and just retains the tape monitor functions.

That was kind of the plan, but I'd feel uncomfortable doing that until it's tested in a 9090.

I do! I designed it (it's my day job) so I am the source of the data. Unfortunately, I do not own any physical boards, so anyone interested would have to foot this on their own. It's cheap, though - 5 boards from JLCPCB was only $26 (that was last year, may have gone up a bit since then).
 
Thank you for doing this. To get the files in the "Database" (it's actually a library) email them to: Audio Karma <ak.pdfs@gmail.com>

Be sure to indicate they are a Sansui Document. I don't know if there are any file type restrictions to what can be posted.

I didn't know that, I was under the impression that email was dead... I tried many times to send McIntosh schematics and nothing. Let alone gerbers/kicad projects and stuff like that.

Good to know.

Thanks!

Hopefully not, but If there are restrictions I'm happy to send to anyone interested. Kind of looks like good timing on my behalf, as the database limit doubled to 40 megs 3 days ago (the zip is 35 megs).

I have a 8080DB and a 9090DB I just got a few days ago so I’d say I’m a good candidate. I’ll get some ordered.
 
By the way, the drill files are tailored for JLCPCB - they require separate files for the plated and non-plated holes. This shouldn't be an issue generally with other suppliers, but If you encounter issues let me know.
