Wow, rooms are a lot more expensive than I thought. When I originally looked I didn't realize how far away from the downtown area the cheap places were. Saving some cash would have been nice, but I am the one driving and that means I would have been the designated driver and thats no fun...

Some of my friends and I are going to Chicago for the weekend. We have no real plans. We are just going to hang out for a few days. We were originally going to stay with some friends, but that isn't going to work out so we need to find a hotel. Can anyone recommend any hotels close to the...

A friend of mine is taking an intro digital photography class next quarter and needs a suitable camera. The class asks everyone to have a 4MP camera that allows the user to select the exposure and shutter speed or aperature. An SLR is encouraged but not required. My friend has a lot of...

My grandfather refuses to move to CDs or any newer media. He loves Frank Sinatra and listens regularly in the car with his cassettes. The cassettes are starting to go bad and my grandmother cannot find any replacements locally. I think she was looking for My Way, but anything would be better...

Are you positive that all of the tabs are isolated from each other? The OPA541s can be connected. Everything else should be separate. I have a Dynahi PSU powering a Dynalo, but i think my resistor values are a bit different so my readings aren't completely relevant. With PSU on and no...

The pots I received are just regular pots, no steps.

My pots arrived today. I actually forgot I ordered these things. These pots are huge. They are heavy and seem solid. I haven't listened to them, but for the money they seem like an awesome value. I attached a picture of the Alps I just received (Black Beauty I guess) next to a Alps Blue Velvet...

I love the Dynalo. I prefer it over the other SS amps I have tried, even my PPA with Steps and diamond buffers. The PPA does seem to excel in some areas, but I just like the way the Dynalo sounds. It is kind of funny, but I have built a number of Dynalo configs and I think I prefer the cheapest...

As I started reading this post the fedex man walked up to my front door and left a package without even knocking. Fedex just leaves everything now and doesn't even bother to knock. I live in sort of a crappy neighborhood and I am surprised nothing has gone missing yet. My old apartment was...

I have one of these boards too, but haven't built it up yet. If the enclosure is flimsy be careful. The tubes might get hot and cause deformation. If you plan on chassis mounting the tubes you will probably have a lot of flex when changing tubes. The build seems fairly straight forward, so...

I received most of that in just over 2 hours last night.

I just ordered a few of those pots from JBLPro. That is the stupidest ordering system I have ever seen. If anyone intends to order from them note that the website is not encrypted or secured in any way. I used a virtual card number from citibank so I am not concerned.

A while back someone let me know SFT was selling 4 channel pots for only $19. They seem like they would be a perfect fit for this amp.

The Dynalo will work just fine on +-15V. The voltage is close enough that you do not need to make any changes for bias or anything.

A lot of dremels come with a fixed size collet that will only accept certain sized bits. If you have one of these you can only use a drill bit in that size. I replaced the fixed collet on my dremel with an adjustable chuck so I can use any size bit. I got mine online, but I think you can get...

I haven't really added any new technologies this year, but a few things new to me: 1. Clipless pedals on my bikes. Speedplay Zeros on the road bike and Crankbros Candy on the MTB. A bit expensive, but definately worth it. 2. The public library and books. I have lived my life on a computer...
