[ProAudio] Proper Grounding Replies

[Corey Bailey Audio Engineering]

Hi Scott,

THX! I didn't think of GFI's. It will take about 50 of them but it's 
doable, a few at a time. As to the iso-circuits: Not in this house. This 
house was originally built in 1932 and has suffered several bad 
remodels. It was listed as a fixer-upper when we bought it (31 years 
ago) but, I had no idea until I really got into it, the initial buyer 
walk-through simply didn't show all of the gremlins.  The bedroom that 
was converted into a studio has no AC grounds so, I drove a stake which 
solved the problem. So, now the household neutral is, most likely 
grounded to that stake.

Bill Whitlock:

I read the part of your article that you pointed me to........THX.

BTW: I was the guy who introduced Deane Jensen to the Analog Systems 
MA332 in the 1970's. Which, will probably start another rant.

Apologies for the OT parts of this post.

Corey
