Pictures of your diy Pass amplifier

Here's my (almost) all DIYAudio system. From the top :


Micro Seiki DDX-1000 turntable
O2 headphone amp, Pearl 2
BA-3 preamp and 1923 Westinghouse DC voltmeter
Fisher 440 and Pearl PS
F5


I'm in DIYAudio heaven thanks to this site!

Wow, Mark! Your rack looks much more neat than my own! All of my equipment is on a rack in another room so the only thing to see in the family room is my OLED tv and a set of FHXL speakers. My rack is a DIY "flexy" style made with sheets of painted MDF and rather industrial looking 5/8" threaded rod that provides a home to seventeen components that drive the family room AV system.

I checked out your website! All I can say is wow.



The VTI racks are pretty cost-effective, but when I added an extra shelf to mine it became a bit wobbly, especially with the heavy TT sitting on top. Nothing dangerous, but with a suspended floor small motions at the bottom make big motions at the top.
 
Cooking an M2X

Hello diyaudio - members,


I`ve got a nice recipe for cooking a new amp - the M2X.
The south german hobby cook sends you some pics out
of his private `MUPPETS SHOW`.
Smorebroed rom pom pom pom....


At first we use some fresh aluminum from the market and
build a little frame.
We need some volts and amps in our meal so let´s add two
SEDLBAUER-Trafos, nice PSU-boards from the diyaudio-
shop stuffed with some fresh fruits from Mouser, Conrad,
Voelkner and some other well known `fruit-dealers`.:nod:


Greetings from Dirk

Cooking an M2X

We are coming closer to finish lunch...



The crazy hobby cook needs a break - burned fingers from hot soup


(waiting for some last ingredients - I hope the yellow submarine from
DHL will arrive tomorrow)


Good night!

answer to MEPER

Hello MEPER,


I had no problems with the JAMICON caps till now. I used them in many
of my amps.
I also used Vishay/BC, Panasonics, Nichicon Chemicons, EPCOS and so on
in different PSUs. I can´t say anything bad about the JAMICONs.
For me its always the ratio between high capacitance, low esr, expected lifetime
(o.k. - promises from datasheets) and the costs.

It is an unwise choice to omit Ccomp1 from your Norwood boards. Read paragraph 3 of the AD744 datasheet, and remember that Norwood is a noninverting amplifier with a gain of one; and if that's not bad enough, Norwood has some EXTRA phase shift introduced by the video buffer, that a plain ordinary AD744 standalone circuit does not.
