Single Channel Attenuator
Thanks for the tip on mouser. It seems they are all raw parts, which is not what I need. I need a finished product. Yes, we could design and make it ourself very cheaply, but since I only need about 10 or 12 units and I need it to look finished it... 
Single Channel Attenuator
Thanks I think the mouser or Gibson is just what I need. 
Rat Shack SPL meter: Analog or Digital?
Eric, the meter is very reproducible, and you would likely be setting levels with a calibrated pink noise, rather than individual test tones. For you what you propose I think the meter would be very well suited, except in the case of comparing an ... 
Soundproof Insulation Queston
The insulation changes the Q factor of the wall and reduces it somewhat. Thus it's resonance characteristic will be milder on an insulated wall vs a non-insulated wall. What is probably of a greater concern is the concrete behind the wall. This wi... 
DIY Record Shelves?
The stock aluminum was clear anodized and I had a machinist drill it out. I bought enough pieces to make 3 units or expand my unit (no the extras aren't for sale). I think I paid about $125 for all the aluminum drilled, brushed, and anodized (yes ...

DIY Record Shelves?
I build some out of 3/4 stock aluminum and hardwood. They are very contemporary and very sturdy. I've posted the plans so that you can download them. They are in PDF format, so if you don't have adobe acrobat, there's a link here for that as well ... 
I need some clarity
I like the Siemens tube idea, but honestly don't think it will get you where you want to be. My guess is your room has a dropped ceiling 2 beds (possibly bunked), carpeted floors and possibly drapes. You have too much high frequency absorption rel... 
Review: Tact Audio Tact-2.2 Preamplifier
Rhintek is working on that issue. That's why they aren't actively distributing the product in the US. I've been told it's very good, but you might be better off just buying the 9 volt for the Rat Shack. 
why does triod mode sound better than ultralinear?
Gs5556: That was a very good basic description, and answered my question. Thank you. 
why does triod mode sound better than ultralinear?
Can someone give us the basic circuit design differences and theory behind ultra-linear and triode? I have heard the two and it is clearly a trade off, but what I do not know is the circuit operation and how it directly affects what I am hearing. ... 
Resonant modes and taming the room
I, like Zaikesman, am very surprised by your findings. However, every now and then some things serendipitously fall into place and what should be a huge problem is balanced out by something else that should also be a huge problem just by luck. Tha... 
Cinder Block Walls
The biggest problem is when two walls are cinder block and you get an imbalance. A three layer buildup on the wall with out the block and adding furring strips, insulation, and sheetrock on the block wall will help. If the block is behind the spea... 
CARA modelling : the best for German speakers
It's a very useful tool, but someone once said a fool with a tool is still a fool. Please don't take that the wrong way, my point is that you still have to use some common sense when using this program--it's not an automated "here's what you need ...
