Gakken’s no stranger to build-it-yourself retro audio gear, and it now looks to be trying to bring some of its old school ways to your iPod with its new Vacuum Tube Amplifier kit. As you can see above, however, while the company is apparently pitching it as an iPod dock of sorts (like we’ve seen before), it’ll plus work just as well with any other audio device, as it relies on nothing more than a headphone jack to hook things up. Of course, you’ll only be able to do that after you put the kit together, but judging from the number of parts that doesn’t look to be too daunting a task, and at about $150, it’s not all that unreasonably priced either (the shipping from Korea could be another matter though).
