In Reply to: Re: Hammond choke 193L installation for dummies? posted by audionutge@yahoo.com on April 23, 2007 at 02:11:44:
Thanks, Alan.Another question: Right now i plug the choke in the receptacle (regular one seen at Homedepot or Lowes) which is next to the one that my power conditioner connected to.
1> should i plug it directly to the outlet where my gears are for better effect? I thought as long as it's in the same circuit, it'll be ok.
2> Even though i carefully connect wire to the choke (heat shrink and electrical tape applied), I'm still reluctant to leave it on all the time. So, i unplug the choke when i leave for work in the morning and put it back an hour before listening. Would it be ok?
Follow Ups:
I now have 7 choke's in my system. 5 of them have been plugged in 24/7 for the last 2.5 years with zero problems. The other two are new, but I haven't had any problems. I have hundreds installed in my clients set up's also with zero problems. On a 120v 60Hz circuit the choke only draws 64mA's...that's nothing...it can handle up to 300mA...which is why the choke is ice cold to the touch.Yes same outlet as system is best.
Thanks, Alan.This is the best tweak i've ever done on my system. It sounds much better than i thought it would be.
Again, thanks for all your best suggestions.
Glad to hear it....enjoy :)
Hi Alan,The chokes are rated at a particular DC current because their inductance will be higher at lower currents and lower at higher currents. See the link.
The choke used as an AC filter will draw slightly less than 64 mA because it has no DC current. However, this does not affect its observed performance.
I expect you are getting improved performance from the 193M because of the higher Ohmic resistance of the winding. Two of them in series should work better.
Al
That is correct Al. I wasn't quoting the mA's specs as a reason why one filters better than the other...I just brought it up as a safety issue so folks understand the choke is safe to use on a 120v circuit. I can't tell you how many e-mails I have received in the last couple of days from people concerned about a/c usage.
