This casual looking bag is a good choice for those looking for a case for their Lumix LX3. The LX3 fits exactly in the case, and the case itself feels light but durable.
The padding in the case is not very thick, so for those who are looking for a more sturdy case, you should rather check out some of the alternatives from Lowepro. But for light travel or handy carrying this one is very good.

Rock-ola Jukebox Audio Hum Help?
This is a Model #481The jukebox works completely, but whenever it isn’t playing a record (which is most of the time) it emits a hum. It’s not “loud”, but it disrupts a room’s quietness enough that I turn it off every time it’s not in use, which is a hassle and makes it feel less authentic/vintage, since jukeboxes in the 80’s didn’t Vintage Rock ola Jukebox need to be constantly powered on and off.I’ve inspected the amplifier, and the Muting & Squelch board looks fine, with nothing blown. The power supply board in the amplifier also looks okay, but has some apparent burn marks behind several resistors. The appropriate resistors still have the right impedance though, and all the diodes are working. My guess is that the power isn’t being rectified or filtered properly, but since I have no means to test capacitors, I’m at a loss. I’ve already redone the grounding, to no avail, and tried a noise filter on the 120V input. Any ideas?I’m very comfortable with testing and/or replacing circuit components, so don’t hesitate to recommend it. You don’t have to “dumb down” your answer either.
