Is it true that drinking Macallan 12 helps attenuate the effects of a trebly headphone?


That is so weird.  How did you know about me and Macallan?   But, since I'm off the sauce I now tame the trebles with a graphic equalizer.  http://www.izotope.com/products/audio/ozone/

 

Cheers and seasons greeting to all  :beerchug:

A qui le dites vous, très cher et très estimable Kevin ?

Living in Paris is an every day challenge :biggrin: Besides the food issue stand the delirious price tag of Stax stuff down there...

for just a moment I imagined you were the master of some mighty sea creature... But if you have to live in a car THAT is a really nice car to call home. wink.gif

I'm suddenly curious to confirm the legitimacy of the parts in my DIY Blue Hawaii. What procedures do you use for testing? Just confirm that the curves appear to match what's expected in the datasheet?

Yours should have the legitimate parts otherwise it would not work in the first place. Justin is notorious about a thorough testing of each components including front panel LEDs.

most fakes don't meet the V breakdown specs - some builders do use a curve tracer to get hfe curves  too

post #4466 of 5784

a lot of the fakes are not even the same pinout. solder them in, power them up, and instant

smoke. The rest like the fake 2sa1968 are 300 volt or lower parts, and blow instantly

when powered up.

imagine that, be rightly pissed off

i've filed 6 chargebacks in the past 2 months on fake parts. most of the time the sellers never even see the parts. they are just brokers. I also found there is a complete lack of understanding in China of the problem with selling fake parts. here is a response I got from a major broker when I challenged the fake parts:

 

Sorry for that, i just double checked with our supplier, these 2 items are made in China parts, so maybe it can not meet your request, but the parts are not fake parts, some customers can use it.

spritzer and I ended up with about 500 fake parts from dalbani

(nikko-electronics.co.uk) very bad people to deal with.

they eventually replaced the parts with real parts, but charged

us additional to do so.

that is such ******** - how can they get away with that. Do you know straight away if the parts are fake? Is there a way of testing. Could they potentially ruin a build if it went unnoticed?
