Thanks, Drunton! I looked at the Hamptone page again. Yes, I do get around 165v for my B+. Also I do have an o-scope and a signal gen. Can you tell me: * What is "sqrt(2)*115=165v"? Either my math needs a refreasher, or I'm not seeing somethig. * I do have an o-scope. When you say "look at the outpu...

Dave, I tried the 12AX7 first, then the 12AT7 with similar results. Are you saying that it will be eazyer for me to adjust gain with the bias resistors if my B+ (high voltage rail) voltage is greater then 200 volts? The Hamptone tube kit seems pretty expensive and isn't for sale yet so I wanted to t...

I was just going to post something lioke this... only for a tube preamp. Where should I look for info on tube preamps to build. Any forums for preamp builders??

Derrick, I happen to think building this stuff is fun, so check this out too. http://home.earthlink.net/~altaflux12ax7/preamp1/intro_preamp.html I am working on this right now. I am a bit curious how its going to sound without audio transformers, but it's cheap enough to experiment, right? Anyways,...

Perfect! Thanks, Trashy.

Thanks Cman! So if I have this right, I don't need a fancy board to check this... just have to compare mono mix to the stereo mix to see if anything has been lost.

Thanks so much everyone!! It is mentioned to "keep checking relative phase all the time". How do you do this? Is this where you do some "soloing" button for each mic or something to check for problems? I don't have any isolation or solo buttons on my current board as it is a very simple one. PS- AUX...

Thanks Cman! I believe that answers my question exactly. So if I have this correct, phase seems to become an issue only when close enough in proximity to another mic picking up the same direct source (even if it's just bleed through). Cool. So I can be more confident in trying more drum micing techn...

I'm self taught and have a question on weather phase is a problem whenever any two or more mics are "facing each other"? I ask because I've been reading many posts on this board about drum micing methods like close with individual mics, the 2 mic method, the 3 mic method, etc. Many suggest trying a ...

Guys, thanks so much! Actually, I am very good with electronics and it is my livelyhood. I like the incredably simple circuit you found Audiopirate, and it seems like it would be a fun place to start befor taking on a $430 kit project. It's so simple you can tweek it to experament with, etc. Nice! I...

Hi all, this is my first post here so go easy on me... :D I need some assistance from the experienced... I'm trying to decide what tube mic preamp would be good for me. I record rock and some acoustic as well and I get a pretty good sound from my analogue equipment already. After doing some reading,...
