Has anyone tried any other 3.3uF caps their buffer? If so, what?

Will take pics of the buffer when the black knobs arrive from Gary.

I like the way they look in comparison to the chrome version!

I am planning to build an acrylic clear case. Can I ask the dimensions (LxWxD) of the Dodd buffer chassis (without the front plate, knobs and feet)? If it is ok. Thanks!

^^^^^
8 5/8" W X 7 1/2" D X 3 1/2" H
Acrylic case is cool, but no RF shield.
Metal chassis is best way to go.
This one is my favor, very easy to work with.
10.4" x 6.6" x 4.25"

I like the clear look but did not know about the RF interference. I'll look for a knobs from the previous post that matches the metal case. It might take me a while to build the case and solder the components since this is my 1st DIY. I'll keep on reading this thread.

Also my mistake... height not length

Thanks TrungT!

I have not used the case but some additional options folks might be interested in. Was looking at them for ClassD amp case.http://stores.ebay.com/gkphotonics?_rdc=1

TrungT, you convinced me-specially after talking to Gary. I had built a mesquite and acrylic case, but ordered the metal chassis. I'll use the mesquite on the front.

Scott,
I am really liking my kit in Gary's metal chassis! I put in the mods for the 6H30Pi tube and having fun listening during the burn-in process.

To burn-in my buffer with the Platinum Sonicap bypass faster, I am putting in the 6N1P tube. Using my old Heathkit pink noise generator, running with a 9VDC rechargeable battery as the input. Putting the buffer on my bench 12VDC power supply and letting her run for 200 hours. Then it is time for more 6H30Pi fun!

I'm still awaiting for those picture(s).

I just got my buffer back with the new tube upgrade. UNBELIEVABLE!

When you can get a DR, you can play at a low volume level and it still good.

Trung,
When Gary sends the black knobs, I promise to take pictures and post them.

Just make your chrome knobs black

Sorry, I thought you already have your black knobs.
I have to let you slice this time

I have had my Dodd buffer for some time now, with the battery and charger sitting in the floor, which is not so nice looking. Yesterday I built a box for the battery and charger from an old HK computer sub, removed the front and back from the sub and made new front and back sprayed with texture paint. I included two outlets so I can run my Dodd and perhaps something else some day. I put a switch on the back to turn the charger off and 2 switches that can change from straight battery to filtered battery. I'm sure most of you have seen the Felix power filter on the Lab section of this forum. The Felix used a common mode choke and caps to filter unwanted noise from AC, it works on DC too. My charger puts some noise into the system, that's why I included two Felix type filters, one on each output. And yes the filters work very well to remove the charger noise.
