Post pics of your builds.... - Page 60

Slick! What kind of case is that? I assume that's a pair of Treads in there also? Nice job (as usual).

Looks like the Lansing MicroPak C style enclosure.

Nice job on the Dantalano (did I spell that correctly?)!

Roger that.
CW2 to be specfic.


Correct.

That is where the tan in the dantanalow name came from.

Do you have pics with the top cover on?

Yea, there are a couple pics with the top on in my Head-Fi photo gallery.

Speaking of Lansing C series enclosures..... why just order one when two is twice as fun?

Hey! Mister X is posting pics of my amp (yes, the exact one) topless!

Dynahi finished

finally, after some delays, I finished my Dynahi. Due to the limited and simple tools I own casework has been hard this time.













The heatsinks (0.45K/W) are a little oversized, it takes about 30min for the amp to warm up, but that's better than running too hot.

I'm absolutely stunned by this amp. I expected it to sound similar to my Dynalos but the Dynahi is even far better. It has an amazing clearity, detail and soundstage. Everything is well defined, tight and under full control. Last but not least I got an amp that is capable of seriously driving my K1000. And the Ultrasone HFI-700 really shine now. I am seriously exited.

Thanks to Kevin Gilmore for sharing this excellent design and to Dan Gardner for the boards. Special greetings to ble0t, thank you for the "kit"

Very, very impressive work Steinchen How big is the case?


/U.

it's 45x33x8 cm (18x13x3 inch), basically it's a 19" case, 2 units in height
weight of the finished amp is 7.6Kg

Your casework is wonderful. BTW, how did you get the heatsinks to fit nicely onto the case, or did it come like that?

that looks really nice, steinchen!

The case came like that. It has been designed with small power amplifiers in mind. I just had to drill the holes for the mounting brackets.

Very nice job Steinchen! That case appears to be absolutely perfect for a Dynahi. Was the front panel done by Front Panel Express? The power switch looks like the Bulgins but I didn't spot any additional circuitry? At any rate, it is a nice and clean design.

yup, front- and rearpanel are made by FPE

correct again. It's a Bulgin like vandal proof switch. But it's a 2x2 pole toggle switch, not a momentary push button, so no extra circuitry is needed.

little balanced brothers: doublemint and double-t

Not yet cased, will get a few Lansing eurocard cases later to house them up.

doublemint:















double-t:











As you can see, both exhibit excess. I love how the caps add so much weight (literally!) to the amp. Hehe...

The double-t is my first serious attempt a complete DIY (no professional PCBs), and while I am pleased with the result I hated the process. So cumbersome...

The doublemint is composed of two MINT boards, and takes balanced inputs for balanced output. The opamp used is the AD8066, with double-stacked buffers (8 total used). The doublemint is powered from a single +24V source.

The double-t is a start-from-scratch double-TPA6120 amp, arranged so that it takes unbalanced inputs and produces a balanced headphone output. It takes power from a +/-12V dual power supply (actually, for now, just a simple wallwart with a TLE2426 integrated into the DIN plug ).

For both, gain is about 2.8 in balanced mode.

How do they sound? Fantastic! They share a similar in-your-face, very detailed and neutral presentation, with the TPA6120 being slightly less clinical.

I'll post some more pics when I finally get them cased up!
