Chinese Little Bear P6 preamp/tube buffer FRAUD

The Chinese are at it again .. On Ebay and some other web sites you will see some info on the Little Bear P6 preamp/tube buffer. Claims are made that this $50 - $75 unit makes your hard sounding solid state amp into smoother "tube sounding" amp. It has one 6N3 dual triode tube. The tube lights up but the tube is not in the circuit. The tube just has a filament connection which makes it light up. Watch the Youtube video below. All the parts in this "preamp" are useless because at about 1:07 on the video he pulls the power cord and the preamp continues to play .. At about 1:32 the fellow pulls out the tube and the Little Bear does not "go into hibernation", it continues to play ! The reason you can't kill the sound is that the only thing working is the volume control. What a rip-off! This unit is just a volume control with a bunch of fake parts on the PC board. I can't believe how many people were probably ripped off when they bought this unit.

Another YouTube review by a guitar player states his sound is "a little bit better" with the Little Bear. Wonder what he was smokin'....

Yes - All the "increase in audio quality" was no doubt in his mind ...

Oh boy......thanks for the thread! I'm a bass player and some of the fakes and low quality replica instruments coming out of China have to be seen to be believed.

Some quotes from audiophile-land about the Little Bear P6:

Thanks GP for posting those "glowing reviews" of the Little Bear P6. We did have an earlier post from January of 2011 showing how some Chinese manufacturers were faking capacitors with a small capacitor inside a larger case. Link below ..
Fake Chinese capacitors
The Chinese also fake more expensive tubes .. See link below ..
Fake Chinese tubes
If anyone else has found any fake Chinese components post the links or photos in this thread ....

The reason this preamp can continue playing AFTER it's unplugged
is that it was PREVIOUSLY plugged into a Wattgate 381.
After the initial plug in to the Wattgate,
no further power is required to operate your device.
Typical newbie reviewer misteak (sic).

Thanks, Tom. I had not looked in at the Amazon.com customer reviews for the Wattgate in too long a time, and once I did, I had a rollicking good time reading them. Something to consider, though: users of the $150 Wattgate should realize that their AC power must also pass through the outlet plate. How many are pairing their $150 Wattgate with a 69 cent plastic wallplate, with unknown dielectric characteristics, from the hardware store? Bob, you are missing an opportunity here. There must be billions of audiophiles just waiting to throw handsful of cash at a perfectionist-grade outlet plate!

Hang on though, there may be some good science behind these units. Heard of the Hall Effect and the Doppler Effect? This uses the Placebo Effect.
Actually I'm considering going into production with a new version: positively guaranteed 10x more improvement to your sound than the original Little Bear.

Ten times more improvement? You should, in the best audio marketing tradition, charge a hundred times more.

It has plenty of company in the audiophile "tweak" world.

Kudos to Bob, Roy, and Kevin for keeping American made tube audio on the move, Shannon Parks deserves some credit too! these Chinese "look a-likes" are simply " money-making" schemes to appeal to tube audio nostalgia of the classics!

These are the same audiophools that will pay $300 for a power cord that runs from the wall socket to their amp. Never mind that pesky unshielded wire in the wall.

I know most folks on this forum don't buy into the hi priced audiophool speaker cableage, but some are fans of those hi fi power cords.
I've not seen any discussion that attempted to address the reality that the AC wires in the wall are pretty humble, inexpensive, simple, "non-directional" (isn't that the funniest hi fi wire claim yet? Directionality?!). How is an audiofile power cord to improve on what 10 gauge Romex delivers to it?
Some of them sure do look good, though.
I try not to judge a speaker wire, nor a book, by it's cloth-bound cover.
Women, however, I still make certain judgments. ;-)

But what do you then connect your $300 power cord to?
Why, of course, a Furutech FI-33R Rhodium 20A IEC Inlet, for $124.99 at http://www.vhaudio.com/connectors-ac.html
It never ends!

Most of the wiring in newer USA homes is 14 gauge or 12 gauge Romex. Sometimes an audiophile may have a dedicated 10 gauge (30 amp rated) line put in for his audio system. This larger capacity AC line won't magically make your audio system any better unless you have many power hungry components on a standard 14 gauge (15 amp rated) line.
I agree also with what others have said about changing out wall outlets to $100+ "audio type" wall outlets. Behind that wall outlet you just have regular Romex wire (or BX wire if the house is old). How is that going to help your music system sound better ?

Doing a Google on this item and others that are total fakes has been an absolute hoot. It reminds me so much of our old shop teacher, who we trolled by telling him we needed to order some of those good old muffler bearings or high-speed bumper bolts....or putting a fake knob on a guitar or something so when that person in the audience or a club owner ragged you for being too loud at a gig you "turned" the knob and they nodded in agreement. Or gooing to "11" on your Marshall amp. I suppose if i did not know these things were fake I may look like a dummy, too, finding new nuances and warmth in my music....so much is in our mind or how we perceive things....

Im sure at best a crappy AMP. Ill have to say, as this is a more highly informed group than the average consumer, that Id like to see an independent teardown from another person.
There is a good chance that this unit was modified to make the video.... we cant be sure
