With respect to Mouser. They are great for parts, especially of very hard to find illumination blubs. But, beware of shipping changes (ask first). If not, you can pay $6.00 UPS to have a $2.00 part delivered. Unless they have changed, they automatically ship UPS ground.
Single Channel Attenuator
I'm looking for a single channel, single ended, passive attenuator. I could build one, but would prefer to just buy it. I would like the cost to be low, under $100. This does not need to be audiophile grade but it can't be of poor quality either. It is being used to set a level for some basic acoustical measurements. Any ideas or products or companies that may have such a device would be helpful.
