Daddy Dee Posted July 25, 2014 Share Posted July 25, 2014 (edited) Thought this was interesting. These folks take quality very seriously. Also Bottlehead has as part of their offerings some entry level kits designed to a price point. I'd take it as a compliment the to the TPA3122 chip turning out 4wpc. Looks like it would be a fun project. http://bottlehead.com/product/quicksand-battery-powered-solid-state-amplifier/ Edited July 25, 2014 by Daddy Dee Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 25, 2014 Share Posted July 25, 2014 Pretty cool Dee. You can get that amp and matching pre for 200. I'll bet the combo sounds pretty good. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted July 25, 2014 Author Share Posted July 25, 2014 Carl, yeh. i think it would sound pretty good, too. I've got the pre-kit unbuilt, but keep pushing that little project out farther on the horizon. Bottlehead says the batteries on the pre will give about 200 hours of service. not bad, really.

NBPK402 Posted July 25, 2014 Share Posted July 25, 2014 I wouldn't mind having it for a HT setup, but I think the batteries would kill me since I have my setup running for around 12 hours per day. Quote Link to comment Share on other sites More sharing options...
The Dude Posted July 25, 2014 Share Posted July 25, 2014 I wonder how one knows when their batteries are starting to die off. You know if the sound starts to lag. Quote Link to comment Share on other sites More sharing options...
erik2A3 Posted July 26, 2014 Share Posted July 26, 2014 (edited) Very cool, Dee! Please let us know what you think about that project when you get to it! Bottlehead, formerly Electronic Tonalities when I got their very first linestage tube preamp kit (the Foreplay) for under $100!, do take quality seriously. Been around for quite awhile, too. Doc B. actually put together the instruction manual for the Lowther America rear loaded horns I put together in the 90s. Good stuff, reasonably priced. He was also among the first to get the antique parallel-feed output stage in SET amps going again -- the next best thing to output transformers short of no transformer at all. The parafeed trannies make it clear size is NOT what always counts when it come to OPTs. Anyway, have fun with the kit!

Sancho Panza Posted July 26, 2014 Share Posted July 26, 2014 (edited) & IF you reduce the price an additional $6, I'll put your AD on it; LoL Edited July 26, 2014 by Sancho Panza Quote Link to comment Share on other sites More sharing options...
Rick J B Posted August 28, 2014 Share Posted August 28, 2014 Is the idea behind a battery powered component that you theoretically wouldn't be introducing any noise from the power grid? I've wondered about this a time or two but never chased the reasoning down obviously. Looks like a fun project and certainly is easy on the wallet. First post, so hello all.

Could be ? I used a T-amp once with a car battery for yard/shop speakers, worked great. I wonder how much noise do you really get from the power grid, I would think (depending on the area) not much ? Good luck DD, hope it sounds great, if you finish it. Edited August 28, 2014 by dtel Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted August 28, 2014 Share Posted August 28, 2014 That is a cool little amp. Bet it sounds good too. Quote Link to comment Share on other sites More sharing options...

Honestly I've never worried about it, but I do know there are big buck power conditioners made and sold out there, I'm sure you've seen them in the boutique magazines. I dunno, my cobbled together system has several things to be worried about before I concern myself with the electricty coming out of the wall.

Moderators dtel Posted August 28, 2014 Moderators Share Posted August 28, 2014 Honestly I've never worried about it Neither have I, there are places I could improve on before worrying about the condition of the electricity. If I heard problems with some buzz or hum I may feel different, but no hum or buzz except self inflected, and that kind seems to improve the sound, and usually the volume level. I concern myself with the electricty coming out of the wall. That must be what causes that pesky static electricity, it's all just laying around on the floor waiting !

Deang Posted August 28, 2014 Share Posted August 28, 2014 Yeah, but you can't hit 120dB and ruin your hearing, so what good is it? There is still a healthy market with an emphasis on high quality sound based on simplicity. I'm a sucker for these low power battery powered amps, and it's great that they put some effort into dealing with some of the deficiencies. The preamp kit looks cool too.
