Default Finally, SR-71 is coming!

After several months of designing, testing, adjusting, manufacturing...Now the awesome SR-71 is coming!

This is the first bamboo artwork chassis tube amplifier in the world! The bamboo is light weight, low cost (comparing to wood with same hardness) and rigid. The front, back and top plate are made of special gold anodized aluminum.

The circuit is all new designed with 6N8P(6SN7) + 6P3P(6L6). Dual feedback + high quality output transformer give SR-71 excellent sound quality. Wima MKP10 was used in the audio coupling path. All resistors are 1% metal film. PCB are gold plated thick copper board manufactured by EzPCB.

SR-71 was showed in a local audio exhibition 2 weeks before. It was one of the shinnest star in the show! We got more than 60 individual order during the 2 days show, ranked no.1 among all the tube amplifiers in the show!

Now it's available for order at Siliconray Online Store, Here it is:

SR-71 hifi single tube amplifier

It's available in kit or assemblyed amp.

Hi Siliconray,

Can't watch your video in Australia. Instead of video, we are greeted with "This video contains content from SME, who has blocked it in your country on copyright grounds."

regards,
Simon

Oh...Don't know what's going on there, what is SME? Youtube is blocked in China but my sister (in Australia) told me it could be seen at the begining.

It's because your culture does not respect copyrights, patents among other things.

SME = Sony Music Entertainment.

The name SR-71 is also taken.

"After several months of designing, testing, adjusting, manufacturing..."
I appreciate your trying to make a living, it does not take months to copy a schematic and build an simple amp into a serving tray.

Clearly you forgot the safety stage in your months of designing, testing, adjusting, manufacturing.
What is concerning is your kits are designed for beginners, as no one with experience would consider your product, even for a moment. These same beginners may put false hope, thinking you actually know what your doing.

Again I got nothing wrong with a guy trying to make a buck, from anywhere, but your out of control, you just say whatever lingo you think we want to hear.

Your video still does not work. We all know how hard it can be to put a video on youtube.

I imagine Siliconray, that the song/music your SR-71 amplifier is playing in the Youtube video in 'owned' by Sony Music, and they have blocked it because you have not licensed it to play on Youtube.

Yes gapmedia, I reliazed that this morning after I google what SME is. I was playing Bob Dylan's Blowing in the wind in the video. Thanks for let me know that, sorry for my improper background music. I will retake the video and upload it tomorrow.

Probably I need to write a song and record a CD to avoid the copyright problem tonight :-)
