Product Description

The BT-4 Blue Tube Amplifier's internals are based off the Model 12M Stereo Integrated Tube Amplifier platform by S-5 Electronics, which is well received in the tube amplifier community. Tube amplifiers have a more refined sound, very different from a transistor amplifier Read More

Does the company/inventor still exist? Anyway to reach out to them? I have had this since it was announced and it's initial release on kickstarter. Still jamming strong, the only problem is the wood seam (between the cherry and walnut) near the tubes has separated due to the heat and I wanted to know if there's a way I can fix it without ruining it.

Looks like they're using the TangBand 4" titanium full range. Not a bad driver considering the cost of the final product. This would be quite nice for a small office or bedroom.

The talking in the video only being in the left channel makes me a bit weary of the quality of this, you'd think audio pros would know how to correct that..
EDIT: Scratch that, carry on! Say the post by BlueTube. I definitely want these. Ugh, money.

Hey guys, sorry our video is so terrible. (we don't even have it on our site anymore since the amp has changed so much from that first prototype) We're working with a real production company for a future video right now. We can cut some beautiful wood and wire some awesome electronics but my video editing skills leave something to be desired! any questions just shout 'em out and I'll try to be prompt in responding.
Rayvolution, The Tubes we use are 10GV8's.
Sanibuy, yep Andy had contacted us and let us know the MSRP was wrong on the site and after I changed it I forgot to press save, it's fixed now.

BlueTubeAudioEither way, these speakers/amp look like a beautiful product. If I could afford this set, I'd join this buy in a heartbeat.

Very cool-looking system, at least from the outside. Has anybody seen a write-up from a well-know/respected amp reviewer? A quick search isn't pulling anything up.

AB01This is what I could find:

http://www.audioasylum.com/cgi/vt.mpl?f=amp&m=164659
Basically, it's a very heavily modified version of the reviews mentioned above. I've personally built the kit version and I've been loving it for 8 years. It's easy to modify and upgrade and there a lot of enthusiasts built around this model.

Beautiful equipment!
That Kickstarter video with its terrible audio (while trying to sell an audio product) is doing it a disservice though.

The MSRP seems to be wrong. The cheapest bundle price on official site shows BT-4 + speakers is $1295, and that's their discounted price.

What kind of tubes does it take?
Also the main picture amp looks a lot different than the other pictures (6 tubes vs. 4 and orientation of the rods). Edit: Pic fixed
