USAFA: Audigy 4 (roommate's computer) ---> DIY GB-150D-based integrated amp (stereo configuration, remote-controlled, power-on delay for output, and heavily class-A biased (3.9mA/channel) LM4562NAs used in preamp section) ---> Yamaha NS-527 (modified with Vifa 6 1/2" woofers, Panasonic film caps in crossover, and heftier internal wiring)
Ghey-C'97 (my piece-o-crap issued laptop) ---> PPAv2 (class-A biased AD8620 (2.5mA/channel), 8600uF pre-regulator, LM338 high-current regulator, 40mA/channel output bias) ---> Grado SR-225 (yes, I bring my headphones home from the Academy during leave)
I had been brooding on it for sometime now and finally got the stuff I needed, white shrinking tube.
Techflex although only one strand braided, but that is improvement for the next version. For now I am happy.
Two hybrid silver High-OFC copper cores, and braided outer also silvered High OFC copper multi strands.
And of course the finishing touch WBT next gen 0110 Cu.
And now ----> Burn In.
And then ----> Enjoy.

I think that could be one of the most expensive DIY iPod Line-Out cables ever... Now we just need to use the Next Gen Silver instead...
p.s. that cable should be in the DIY cable gallery

Finished this A47 recently. It's the second amp I've built. Nothing fancy so no inside pics. The only thing to inform is the potentiometer which is an Alps RK18 (never heard?). The two 2134's are fed by 12 batteries located in a different enclosure (not shown). Power is transferred via 4-pin mini-DIN.
I built this to power my 595's but I still prefer my stereo amplifier so I'm planning to sell this one (send a PM if interested, Scandinavia preferred). Next up, Dynalo. Everything is already planned, only the money is needed...
This was my first post but I've been reading Head-Fi for 8 months. It's been a fantastic source of information (but a nasty thing for my wallet).

Why did you use 2 OPA2134's? Wouldn't 2 OPA134 be same and perhaps suck less power at the same time?

The A47 uses an opamp in each stage, so you need either four single channel, or two dual channel op-amps.
That's a very clean-looking case job, Tsappis. Very nice!
Welcome to Head-Fi, and I was going to say sorry about your wallet, but when your first post is in the DIY gallery, you clearly are already on the road to financial ruin.
Finished my Cmoy a couple of months ago, I designed the layout with the aim of fitting it into the smallest enclosure I could (a cigar tin) with a 9V battery. It has two circuit boards, one on top of the other. It's a standard cmoy but without the input caps. Opamp is socketed and there's a zener diode for low power LED shutoff.
Wow! Thats a might fine job you've done there!! How big is the whole thing when its inside the cigar tin? 2 times the size of a 9v or something?

Thanks! The cigar tin is a bit less than twice as long as a 9V. The dimensions of the tin are about 3.2" x 1.2" x 0.9". The cigar brand is "Cafe Creme". If anyone's ever interested I'd be happy to share the layout.
Bigger isn't better!
