Audio Research amps - balanced & non
Will these problems occur with any fully balanced amp or preamp used with an XLR/RCA converter, or only ARC? 
Capacitor log Mundorf Silver in Oil
To the point raised about EMI generated by large inductors, has anyone tried Ti shielding? 
Phantom custom mount on SME slot?
I have VPI and Graham TNT armboards cut for SME & Graham 2.X respectively. I believe the 2.X pattern is same as Phantom? It's not practical for me to overlay these armboards right now, but I looked at it awhile back. Overlaying the Graham cut-...

Marty, You could be right, but the difference between balanced and unbalanced operation is more typically described in terms of loss of gain(typically 6db) and signal-to-noise ratio, due to sacrifice of common mode noise rejection inherent in bala... 
tt isolation help
This reminds me that I have an old set of Audio Technica spring footers as well. They are better suited than the McMaster-Carr springs to being placed directly under a component. The MC springs work best when mass-loaded by placing a heavy plinth ...

"The VT-130SE does not have a phase splitter and requires a true balanced input to operate correctly."It will operate "correctly" but not "optimally" in conjunction with a single-ended source. With an SE source and an RCA/XLR adaptor, one phase of...

Trip, The springs are McMaster-Carr P/N 96485K125. They are 1-15/16”D x 4”L and use .148” diameter wire ground flat at the ends. They compress 23.7lbs/inch, up to a total deflection of 2.88”. So a 50lb load compresses each spring about half way do... 
6C33C-B tubes
The pair of 6C33C-B tubes providing 75 wpc in my BAT VK75SE are biased 200ma with 210V plate voltage. They begin to degrade sonically at 1200-1500 hrs. I have not needed to replace a tube socket in 10K hours of service. 
DIN to RCA adapter
Brent, These pins will mate directly to the cartridge clips. In DIY I use high-quality gold-over-copper male/female Bulgin pins in various sizes for intrachassis connections. http://www.alliedelec.com/Search/ProductDetail.aspx?SKU=565-0058&MPN... 
DIN to RCA adapter

Velodyne's Dim View
I've had several productive conversions with the Vel's Arizona product manager as well. You could probably just pull the bulb from the rear and ID it for replacement.As good as it is, the DD series is getting long in the tooth and Velodyne should ... 
Has anyone here tried the Lightspeed Attenuator?
Clio09, Was that the Audio Consulting TVC with their premium Silver Rock transformers? 
phono preamp with volume?
Atma-Sphere balanced tube integrated phono preamps are fantastic, as is Atma customer service. 
Joule LA 100 mkIII and Bat VK 60?
VK60 has good power & tone for Merlin VSM & can be significantly improved with DIY mods similar to my VK75SE.
