Hi all,
Just bought a topaz line 2 which is a ferro resonant voltage regulator. When i plug my monoblocs into it i get a loud hum through the speakers. When i plug in my girlfriend's boombox there is no problem. What is going on? The monobocks are british solid state (quad 50e). Does this have something to do with how british gear is grounded?

That's a switching device. I wouldnt use it. Anytime you use two seperate amps on one system you are vulnerable for a ground loop. Certainly you need to put a cheater cord on one of the two power plugs to eliminate a potential ground loop and see what happens. Good luck.

First NOBODY ever died or even had an incident from lifting a safety ground. My gears safety ground have been lifted over ten years. Also I said to lift it as a test with a cheater plug not permanently.
As someone who uses both a biamp as well as an AC regenerator both of which can create ground loops I know the value of lifting ground at least as a test. The OP has monoblocks, two different ground points and has ground loop potential.
By the way once year I go visit all the audiophile and other electronics geeks graves who died from lifting grounds..........

Oh, he's only supposed to do it temporarily. It's a test. But a test of what? To see if he should incorporate a cheater into his system as a permanent safety hazard? Give me a break. You have no idea how many people have been injured or killed by removing safety grounds from equipment, or from using equipment made before three-wire plugs. Those grounds are there because people have been hurt. Telling someone otherwise is the height of stupidity.

Are the British mono blocks 2-prong?
thanks for the info
I plugged it into another outlet and the problem is gone. I live in an apt. (and move a lot) and the outlets are often not grounded properly. I thought this device might help with that problem as well as general line noise. I know I should have a dedicated line etc. but even asking for an electrician to fix the outlet would draw an interesting reaction from the property manager. And I'm not sure I'm allowed to call one at my own expense. I imagine it draws more amps than the amplifiers did, because I didn't have a problem with the outlet then. I've got another topaz line two coming, and an ultra isolator for my front end coming as well.
Grounding issues are safety issues, the manager better not
have a problem with fixing it. You can get $5. plug-in tester
that can prove a bad ground situation. Get the outlet replaced
with a decent one and make sure the screw terminals are used,
rather than any "push-in" connections.
thanks,
will get a tester.
Good...and test every outlet. Bad ground could be at any outlet (they
are daisy chained in series), or can be at the electrical panel. I've
seen real sloppy ground connections behind outlets...just twisted
together wires with no crimp sleeve or wire nut. A GFCI outlet
in the circuit will detect bad grounds and trip off. Or,
a GFCI breaker can be put in the panel for that circuit.
