photos of my creations

I thought it time to post a few pics of my creations.

Photos of my AKSA 55N will be posted soon, and I will be modifying the site to give more details and photos of my projects.

I was very pleased that Jim Hagerman announced me as DIY'er of the month for August. I love my Cornet2.

Anyway, the URL is:

Charlie,
Beautiful chassis work!

Keep up the excellent work Charlie, no need to worry about your wood working skills at all. Your Cornet2 Phono stage is stunning! I absolutely love the base!

Hi, great looking amps congratulations!

have you used seperate volume controls per channel on your Aikido? if so does it work ok? or is it a pain matching the levels?

edit: reread and your using a goldpoint attenuator, thought those 2 knobs on top were the controls.

Craig,

I have six inputs going into the Aikido, one of the knobs is a source selector. The other is the volume control.

Incidentally, I have noticed that my "cheaper" devices (DVD player, TV, tuner) caused hum. This was almost certainly due to a ground loop with these devices (none of them have dedicated Earth pins on their plugs). Anyway, for the RCA jacks on the Aikido where I plug these devices, I simply disconnected the Signal GND. In fact, the only RCA jacks that have singal GNDS connected are the CD-player (Rega Apollo) and Turntable/phono, and the output to my main amp.

Are you on cable TV? That would do it.

You can buy a cable ground isolating transformer that should eliminate the problem.

Chris,

No, I am not on Cable TV, just regular analog via a rooftop antenna.

Hi Charlie,
You may not be on cable, but if you use a grounded coaxial cable system, the result would be the same. These transformers are a 1:1 type, the better ones giving you less loss. They break that other ground connection that is carried over the cable shield and RCA connectors.

Try disconnecting the antenna connection on all these and see what happens.

Chris,

I'll give it a try. When I rewired my house antenna, I ensured that the coax was grounded on the outside of the house via the same ground point that the cable company had wired. Last summer, the cable co cable broke and we didn't bother having them replace it. Our provider is Mediacom and we didn't want to give them our money for anything.

Thanks,
Charlie

Hi Charlie,
Wishing you luck there. At least you can test the idea without spending anything.
