And not that Rick and I generally agree but holy poop that seems like buffers for the sake of buffers...

and not a heat sink in sight

Has anyone else noticed that it uses the fake ALPS Blue Velvet "RH27" pot?

holy moly... do phones really NEED that much current reserves? That looks like enough reserve power (voltage / current) to power a small stereo.

yeah,the artificial ground circuit and not the audio signal circuit so he don't burn up the buffers trying to drive the other buffers

Read the data sheet on the BUF-634 folks.You ONLY get the full current output delivery if you properly heat sink the buffer and the reason for the metal tab is not because it looks "cool" but to allow the internal transistors to be cooled by attaching a large chunk of heat dispersing metal to it.
you take an unheat sinked metal power tab pack buffer then close it up in a case where there is zero air flow and you do not get close to the rated output.


you are looking at probably a 6WPC amp if properly heat sinked but no more than what a single buffer would do (other than reduced out Z) if not.Kinda the cart leading the horse in my opinion

it is deceptive.That amp does not put out the current it seems (see above post ; ) )

Oh well. If less than $100 I would still buy it and remove the buffers since we are on a shortage of BUF634s

Oh and I'd have a nice case for another amp, a fake blue velvet pot and a nifty battery pack to play with

assuming they are not counterfeits.Very common from what I can tell with chinese amps and have done the math on a few by adding up what parts would cost even in quantities of 10K and when compared to final amp cost before it is even cased up no way !

There is zero way some of these amps have what they claim to be inside and in fact go to such great lengths to show in close up shots and sell for the asking price.the parts if legit cost more than the amp so who is conning who ?

am I to seriously beleive someone is building and then selling amps at a loss ? They are just in it for the service to humanity ?
Or would it be more beleivable they are either cloning the parts (counterfeits) or slipping a "Black Gate" sleeve (for example only !) easily printed on a low ball suspect generic cap .

Is there a website to these amps?

rickcr42, you're busting my realism levels lately, thanks for that

It is a curse man !

I was totally happier when I was dumb,young and ready to run

I'd have to say that after amb noted the knock-off Alps pot that I seriously question the integrity of the rest of the amp's components.
