Default Latest project almost done & Hello from Hamburg, northern Germany!

Hi y'all!

As I´m a DiyAudio Member since May 2004, I think it´s high time to introduce myself. So, about me, so far: 46 years, quite offbeat, no children. I'm vegetarian, I love being outdoors (especially in my garden plot), do a lot of reading, got no tv (listen to the radio instead) and put on some music every day. I was employed as an IT manager until last week (company went bust) and now I'm going to be a freelancer. My roots are in the 80's punk and indie scene, I had a restless, unsteady, vibrant, but also hard and troublesome time before I got some settled. When I was in my thirties, I thought I'd never get this old ...

But now I return to the charge: As I cannot afford HiFi stuff that satisfies my requirements, I have to build it myself and the following is what I (almost) finished just yesterday night:

From the left: Large heatsink with 2 SymAsym 5.3 "AAK model" and 2 LM3386 GainClones from chipamp.com. Next above a transformer wired to a bipolar PSU from Twistedpearaudio.com, feeding a pair of Thel SAW30 3-way active crossovers. Then a piece of an old computer case in which I crammed not less than 7 transformers and the PSU for the Gainclones. Wiring was a big fun ... Click the image to open in full size. To the right of that I mounted the PSUs for a pair of plain vanilla MOSFET amps (Sanken 2SK1302/2SC3281). As this setup is the intial test, there is yet no case.

Some details:

Absolutely no hum or hiss, totally noiseless!

Driven by all that are 2 of these:

On top it´s Jim Griffin's MiniMonitor, an E.J.Jordan JX92s with an Aurum Cantus G2Si in 8 litres. Below a 'RiPol' woofer.

If you sat on my sofa, you'd see this:

Without diyaudio.com I'd have nearly no clue and I'd definitely not been able to tinker the stuff shown and all the stuff I made before. Thanks to the folks who helped me, thanks to the nice guys who keep this going! Special greetings to Russ White and Brian Donegan! These guys got me hooked on this ...

If you're around, post me a PM and I'll invite you and your favorite CD.


Cheers,

Gerd

It is a wery impressive setup you have. I like the fact that you have done it all as DIY- that takes some comitment and tons of research. Well done

And by the way, off beat is better than main stream. It is what we learn from our mistakes in life, that gives us experience and focus- not the other way around.
