Ground loop issues in D-lator

[erwin_ve]

Did you ground the back of your pots to the buss bar?

Thanks, soldering the ground buss to the back of the pots was the magic bullet!

Apparently the buss needs to be attached to the pots because the paint keeps the pots from making a good connection. In fact the back of two of my pots read to ground as an open before soldering them to the buss.

Thanks to everyone that helped me today. Maybe this will serve as a resource to others with D-lator grounding issues.

Great, glad I could help, enjoy!

No offense taken. I know they are bad. I originally built the D-lator with some extra solder, it was lead free. Afterwards, obtained some 63/37 solder, but my iron is not heating correctly, my tip is shot, replacing the tip today and afterwards clean up the job.

That's too bad.
That lead free solder is junk.

I tried to repair an amp that was soldered with that stuff and it was
terrible stuff.
Dry, crumbly, no flow.....

I wish before they had mandated that stuff they would have done a lot more research.
Or perhaps have a much more stringent recycle program for electronics to keep the lead out of the ground.

Funny thing is, it originally came out of the ground as lead ore.
