monster powerstrip problem

General Asylum

General audio topics that don't fit into specific categories.

An aquaintence of mine had a monster HTS1000 MK II, it had a problem. The switched outlets on the strip didn't work.
I pulled out my trusty 3 neon light outlet tester, plugged the sucker in..
It indicated hot and ground reversed!!
Whoa! So, checked the unswitched, they were correct..
Figured this was like the APC thingy coupla weeks ago here.
Took it home, used a DVM to check it out..ground was correct..hmmmm..but, both hot and neutral showed about 40 volts to ground??
Turns out the switched outlets have goop across hot to neutral, transient supressors or something similar..and these outlets have hot and neutral go through a common mode choke.
The neutral and hot connections between the common mode choke and the outlets had broken solder joints. When I disassembled the beast, I noticed the neutral wire had three depressions in it, it was jammed between the case and the choke, it pushed the choke into the pc, this broke the joints.
Resoldered both compromised joints, put the unit together, and the thing works perfectly.
The initial dumb tester results really alarmed me with that reversed hot-ground thing, but it turns out the tester is not capable of wringing out all outlet issues. A broken neutral wire at a duplex outlet, with another load on the outlet will also indicate this.
While I fault monster for quality control, there was no safety issue with the device..
Is it possible the APC unit also had this problem?
