Greetings all, apologies if this has been reiterated ad-nauseum but an initial search didn't reveal any results. I have a CKKIII that I built a couple years back and I've been experiencing troubles with a buzz from certain sources (in particular, sources that share a common ground). For...

Quote: I think what he's saying is that this is a headphones forum and speakers aren't really what we do here.   Granted, our beloved B22 amplifier will also do speakers (and its older brother, the B24, is designed exclusively for speakers I believe), those amps are quite difficult...

Quote: Good luck with your build.  Hope it all goes well.

I use a Tenma that's basically a cheaper clone of a Weller.  By no means an ideal situation though, you can't go wrong with Hakko or Weller.   As far as repairing the lifted pad, green wire fixes are the big thing.  Its not all that pleasing and you may just opt for a new board, but that's...

Quote: Well, I'm not specifically stating you in particular are going to have a substandard B22,but I was just looking at your estimates being in the sub-$400 range and remembering when I went through to calculate costs I was looking at $400 for just the boards, not even including any...

Quote: Keep in mind I'm also a systems administrator during my day job, meaning I'm VERY jaded and cynical   I just tend to err on the side of caution rather than rushing into projects as that's gotten me into trouble before.   But I guess I'm also kind of wondering why would...

Quote: Personally I kind of have to agree with the building up aspect though.  The boards are actually the least of the concern.  What becomes a big concern is your ability to deal with problems and the complexity of the amplifier.  Once you start air-wiring components and having to...

Quote: Quote: Yeah I've since removed the foil since it wasn't even the toroid that was creating my noise issues.  I was afraid of something similar to what you were mentioning   Thanks for giving me the heads up on that one.

    Ok, so its not very pretty inside.  And I pulled a redneck DIY deal and added some extra shielding to the transformer in the form of some aluminum foil.  Its grounded out though.   Actually the build is probably pretty laughable to someone who knows what they're doing, but this...

You might take some slack from the B22 before attempting it.  Its a pretty complicated project and its good to get some more practice under your belt.  AMB/Cavalli's CKKIII is regarded as a mini-B22, but is significantly easier to build and doesn't require a lot of special casing.  Its also a...

Fixed this issue, I had the terminals on the headphone jack mixed up.     Tip = Left Ring = Right Sleeve = Ground   Now to commit that to memory.

So I'm at a bit of a loss at the moment.  I've finished building my second CKKIII (never got the first one working so I scrapped it and started over).  After replacing the board with a completely new one, with new components, replacing the voltage regulators with higher quality ones, trying...

I think you have me all wrong I'm certainly not knocking on tubes (I'm building a CTH specifically for experimenting with them). I'm just saying in general people who like tubes tend to prefer the "warmth" of a tube amp, just as a very conspicuous example, not that they alone prefer colored...

Quote: Originally Posted by nikongod How do you know the CKKiii is not colored? It sounded a little smooth to me the last time I heard one. CKKIII is colored in my opinion, obviously it has the sound of a solid state amp, plus other characteristics I'm not implying that amp's...
