I tried to do a little detective work last night with no results. I have a phone number somewhere in my email backups but haven't found it yet. I know he started a major project outside the DIY world a few months ago.
I'll keep searching.

Some of you may have heard from Uriah and know the news is not good news, but he is working to ship all the orders it just might take a while.

Guys its Leukemia. Making me extremely tired. I basically can do one job a day. Mow the front patch of lawn or take my daughter swimming and I'm done. When I get a good day and over do it I am out for two more. Hoping to get it under control, the tiredness, soon. Hemoglobin is real low cuz of the meds so not a lot of oxygen getting retrieved from my lungs, at least thats my take on it.
Javier Galvan and I talked today and he is going to take over kitting for me. Hes a real good friend and knows LDRs very well as he has been helping me for about 3 years now. Outstanding orders of just kits are about 2 weeks out, my guess. Built units even further. I can refund if you need me to and its no problem.
Love you guys and hope you dont have to put your family through this. Go get a complete blood screen. I found out in a routine cholesterol scan but it has to be a complete blood count. Its easy and so is a colonoscopy so do that to. Seriously a piece of cake. They slightly drugged me and I thought I was watching TV.
Next thing you'll see from me will likely be an integrated amp. Year end probably. Also will likely be just a board. Oh and I will be redoing the Lighter Note into something much simpler to assemble using only the necessities from the LN design. Right now its to big, to complicated and to expensive so I know I can knock it down and keep the sound quality.
Heading for bed. Take it easy.

Hello guys!

Uriah and I have been talking on and off again about lots of subjects, but mainly his health, as he has to make adjustments in his life.

For now, I've offered to help him out. I'm a busy guy with a regular job as a test engineer, and a family of my own, but I spent many years working in kitting operations for a major computer manufacturer and a small company here in Austin. So we plan on getting our ducks in a row as soon as possible, getting things boxed up, and shipped.

As Uriah has said, he has loved doing this and helping all of you out with builds or questions. He thoroughly enjoys hearing about your positive experiences with the various LDR products out there. But as he said, his reservoir caps are a little low right now. Feel free to shoot me a PM. Uriah and I will prioritize things and get you an answer.

@uriah

I am oncology imaging specialist and a diyer too, though on a different continent. What does the immunohistochemistry test say? Hope it is curable variant of leukaemia. Try to follow you docs orders and stay away from infection.

Get well soon!

Thread revival! I was thinking about adding some of these to the brianGT LM1875 kit and to a phonoclone VSPS 3000 kit. Should be interesting, think it would be an improvement? I figure in the VSPS its so early in the signal path that's where I should see the most benefit.

Hello,
I have a very silly newbee question for you, but first of all I'd like to wish to all of you and in particular to uriah a happy, successfull and healty 2013.
I'm very interested in this mod and in general about LM1875 and LM3886 mods.
But one doubt I still have specifically about using this LDR in place of R1 resistance that is in the signal path: why do not simply leave out the R1? I mean what could the sonic difference be between a line of wire, an 1k resistance or some 220ohm military grade resistance, and this LDR?

Thanks in advance for explaining,
tent:wq

First lets not assume military grade means anything more that more robust and more accurate over an operating range. That said though, Dale military resistors are pretty good. Thats what I upgraded from in my chip amp.
I have a customer that is using ldrs for attenuation. He can also adjust volume digitally. He says ldrs add a subtle softness to the sound. I agree. Whats different with ldrs is that there is a softer and sweeter sound, more musical than without ldrs. We get this with no loss of transparency. No addition of a veil. My feeling is its due to resistive material, like when using tantalum resistors. Straight wire will nit be as sweet but will be hyper transparent.
