You got to pity the people of Libya. They must have what is likely the slowest connection to the Internet...
november 29, 2009: The Swiss vote to ban minaret construction
february 26, 2010: Gaddafi calls for jihad against Switzerland for banning minaret construction
Today a package containing parts arrived. I now have all the parts to finish the B1 buffer preamp except the case. The cMoyBB is nearly finished, I'm waiting for the Alps pot to arrive.
The cMoyBB got hooked up this evening to check voltages. The LED lights up and the rail voltages are half the supply voltage. That's good! It means the TLE2426 rail splitter works. I played with two different values for R_LED. The default value is 24K, I tried 33K too but found the 24K a better choice.
OK, I'll have two of those please. With milk? No, milk is for cows you silly twat! I'll have mine with Glenrothes Single Malt Whisky. :-)
I was in record shop recently and there was music playing I didn't know, but I liked it a lot. A very distinct voice. Now where did I hear that voice before? Then I got a hunch it might be that bloke who sang Daughters, a great song IMO. Wasn't that John Mayer? It was indeed John Mayer and they were playing the Battle Studies CD in the shop. Since then I really discovered John Mayer much to the dismay of my wife. I've been playing Continuum almost non-stop the last week... The John Mayer Trio (with Pino Palladino and Steve Jordan) is high octane blues! Recommended listening.
I received my order for some B1 parts today. I now have the 1µF and 10µF caps, the source switch and the Alps Blue pot. I also got 26 2SK170BL FETs. For optimum performance the two FETs per channel need to be matched for Idss. Not a difficult job if you know how to do it. It just takes some time. So I'm looking for two matched pairs. I asked the knowledgeable forum members at diyAudio.com for assistance in selecting the pairs.
A large yellow envelope from the USA in my mailbox today. Upon opening I found a Packing Slip and a small anti-static plastic bag thightly folded over a couple of times. Aha that must be the three blue LEDs I ordered. But where is the PCB I ordered? I looked into the envelope again. No PCB. I opened the anti-static plastic bag and out came the three LEDs and the PCB. I knew it had to be small but I didn't expect it to be that tiny. It measures a mere 40x47mm.
My PX-100's. Love 'm. Really nice headphones. Nothing high end though. Very decent headphones for an iPod IMO. Better than supplied crappy earbuds. I noticed there was a rather annoying buzz in the right channel though. Especially when there's deep bass in the music. Damn, I don't want to have to buy a new pair. I took off the foam pad and looked at the driver. Nothing abnormal. Just a clear diaphragm. I blew a few times onto it and while looking at it with a bright light I saw something lodged in there that wasn't supposed to be. A hair. Carefully I managed to remove the hair. An eyelash to be precise. And now? Mission accomplished. No more nasty buzz. PX-100's sounds like it should again.
I found a Barkleys mints tin in my locker at work today. Mints expired a year ago... They didn't smell like they are supposed to. LOL.
I'm gonna make myself a cMoyBB headphone amp... I ordered the PCB yesterday (a red one, because everybody knows red PCBs sound way better than ordinary green ones).Now it's parts sourcing time.
I'm gonna use a mints tin to house the amp. Everybody and his dog uses Altoids mints tins for this. Unfortunately there's no Altoids to be found locally. I can however lay my hands on Barkleys mints tins. I'm gonna use an empty red "Cinnamon" tin if the PCB will fit inside. First thing at hand is to eat the mints.
I've been playing with the cMoyBB Frequency Response Calculator. Nice Java tool to visualise the frequency response while you alter component values.
