Re: Vinyl: Jack White's Third Man Pressing in Detroit

Did Josey buy the cutting equipment too?
I had been told by a neighbor that was familiar with A&R and the sale that they had purchased the cutting equipment but don't see any references to it online.
It may just be in storage.

Re: Vinyl: Jack White's Third Man Pressing in Detroit

Paul - Have you had any contact with Josey records? http://joseyrecords.com/

They bought the old A&R equipment and have moved production to an Old Dave and Busters warehouse.
I need to drive up to their store and have a look.

Re: Entropy

February is capacitor failure month. It began January 31st when the HVAC evaporator (inside) blower fan failed. The capacitor was swollen. The blower motor itself had also failed - the smell of burning windings was pretty strong and, after initial cap replacement it thermaled out. That evening I ch...

Vinyl: Jack White's Third Man Pressing in Detroit

Walk into Jack White's Third Man Pressing record plant, and you're greeted by a burst of stylized sensations: A glossy sunflower-yellow floor. Tables stacked with a rainbow of colored LPs. An eye-catching mural by neighborhood artist Robert Sestok along a back wall. Music drifting across the acoust...

Re: Using the THAT1646 As A Transistor Pre-Driver/Headphone

Wow, thanks for the feedback Greg! You sure can use a 1243 but I would recommend a 1240 for most headphone builds. I built most if not all of the line amp versions with 1246s but I never found a headphone application that required the added 6 dB attenuation of the 1246. Still, with some phones (e.g....

Re: THAT2252 RMS Detector Replacement Using A THAT300 Array

I was able to check the DF not the DA.

A Nichicon 22 uF UVR electrolytic measured 0.19 DF; a 22 uF tantalum 0.03 DF.

I was going to use a film capacitor anyway in my build.

Re: THAT2252 RMS Detector Replacement Using A THAT300 Array

Tantalum capacitors, which have tighter tolerance and lower DA excel as a Ct.
...compared to the commonly-used electrolytic timing cap.

My thinking is that a 22uF film (or a pair of 10 uF films) would be the ultimate timing capacitor. (And would be impressively big.)

Re: THAT2252 RMS Detector Replacement Using A THAT300 Array

Gary Hebert of THAT sent me a variation of the current rectifier which uses Q2 to pre-bias the rectifier in class A-B similar to the THAT2252. Gary liked JR's common base stage, Q9. http://www.proaudiodesignforum.com/images/jpg/THAT_300_Based_RMS_With_Current_Rectifier_800_BW.jpg THAT2252 replaceme...

Re: "fingers" on edge connectors

Part will become a non-stocking item when stock is depleted Looks like that Sullins part is discontinued at Digi-Key. MicMix used a male right angle similar to the Sullins in some of their very early Studio C Reverbs. John Saul, one of the co-owners, had been an aerospace engineer and refused to us...
