Improper ground


Okay, I've got a 20A circuit with 5 receptacles in the chain. Only one of the five have proper ground. As far as I can determine it's the first one in the chain (has a switch also, which btw when I turn it on/off a "pop" can be heard from my speakers). I have a 7 outlet power strip plugged into the grounded receptacle, which comforts me and where I plug my modest gear into since it's grounded.

All the receptacles in the circuit are getting exactly 123 volts each.

By plugging my amp straight into the improperly grounded outlet what are the risks here? Damage to the amp from normal every day usage (don't believe so). Should I get an electrician in here and ground the outlets.

I'm interested in whether I should be concerned with plugging my gear into non-grounded power socket(s)...

Turns out they used two wire cable to string up my circuit after the first outlet in the chain. So no ground was present because it wasn't in the power cable! Had to cut the box out; drill two holes in the corner walls to fish the cable thru; cut the 2 wire out and fish the new 12AWG Romex between the 1st and 2nd receptacles.

Electrician had "really shaky hands" and I was nervous watching him attach my $144 Oyaide R1 AC Receptacle. His helper got electrocuted when trying to grab the fishing wire thru the cutout in the wall of the old outlet. On several occasions I offered to switch the breaker off because he was just charging ahead with live wires. Cost me $150 for 1.5 hours work but some of that was entertainment.

The remaining 3 outlets are still improperly ground in the chain but I only plug a cable modem and router into them...
