Post pics of your builds.... - Page 61

Just got the last part (toroid) for my DynaHi. Now time to case her up.

Cassette adaptor for my car's cassette deck. The original cable was too long and flimsy, so I put in more rugged cable and a Neutrik plug. Not too fun taking the original adaptor apart, but it was a good challenge and the results made it well worth the trouble.

Switch box for my laptop. This has a DP3T toggle, where the center position is "off," so that I can mute the music in case of a phone call. My set-up is such that I either use headphones at the desk, or feed music to the stereo for the room.

Here's my M3 - What can I say, she sounds awesome. Compared to my PPA, the bass is stupendous. So much bass in fact I can't listen with 650's for that long. But, paired with my Ety's at work the match is great. Unfortunately, now I've heard the M3, my home PPA is sounding a little sterile. The M3 is pretty much stock build with no boutique parts at all - The first project to come in on budget!!

The outside. Didn't fancy another Hammond 1455 case so got a plain old cast aluminium box and painted it with hammerite:


And the insides - Nothing too fancy here and a reasonably tidy build for me:

PS. Gawd bless stepped drill bits.

Tangent's PIMETA "breadboard"

Tangent's PIMETA Breadboard

-Socketed IC's, resistor block, bandwidth and cascode resistors.
-Molex KK pins - tin for PS, switch and LED; 20um gold plated for the signal pins.
-Soldered - caps, pot, R1/R2 divider, LED resistor

Pls notice that cascode resistor sockets are mounted low with respect to the OPALR socket and transitors are firmly pressed to the board so there's enough clearance for a resistor to fit below (dual) BrownDog.

And same PIMETA - mounted in a wooden box





Here's the final configuration (for the relatively blant Sennies 580)

-AD8620/8610
-Diamond buffers (MJR243)
-4x1000uF Panasonic FM + 2x3.3uF Illinois Capacitor film caps
-Gain is 6.78
-Class A casscode
-10K pot/100K ground res
-24V regulated PSU (30V/400mA wallwart + "drop-in" LM7824)

Pinebox PPA

Well, this is really the combination of a couple of things, but what the heck I feel like I haven't completed something in a long time so this is therapy .

The enclosure for the Pinebox PPA was built as a result of prototyping a case for a friend's Millett which is languishing at my dad's shop as I continue to work like a madman. The amp section is a fairly maxed PPA V2 with Elna Silmic II PS caps, class A, OPA627s, gain of 4, bias blah blah, etc. etc. Power comes via a fully populated STEPS using Nichicon Muze caps and running a healthy 28V. Best part of the amp is the stepped attenuator which aside from the 4hrs (or so) it takes to build is the best sounding $40 volume control I've heard. Enjoy the pics and sorry for the marginal quality had to use the backup cam as the D70 is out getting cleaned.

Another M³ with STEPS

Didn't think I'll need more inputs, still missing input switch. But "completeness" of this thing is entirely based on the fact that I finally made that square hole for snap-in IEC socket That was the biggest problem in this project. "Illumination" comes from two standard STEPS and M³ PCB leds. Enclosure is PAR-METAL 20-12082N. Thin HDPE sheet isolates whole top cover and sides.

My WNA MKII amp & my CD650 tuning

Hi,

Wallwart with toroidal and Tread

This is my first selfbuilt piece of electronics:
A wallwart with a 15 VA toroidal transformer and a TREAD board. As you can see it fits very nicely (and tight!) into the walwart casing. I used the wallwart casing because it cost me only EUR 4,50 and there is no need for an IEC inlet and fuse.

My CMoys and MINT

I love this DIY hobby. It's something I've had in my mind for many years but didn't act on. Now that I have started, I can't stop. HELP!!!!!

The Marilyn Monroe is not my build. It is a PA2V2 that I removed from the plastic enclosure that it came in.

Superman mini lunch is a MINT. Elvis tin, Altoids tin, and Ohio State mini lunch are CMoys. I built another MINT in a New York Rangers mini lunch for my son. I have a James Dean tin and numerous Ohio State(GO BUCKS!) tins and mini lunches yet to use. Anxiously waiting for recently ordered CMoy2 pcbs(I despise the Radio Shack board) and the soon to be released PINT and Mini(cubed). My longterm ideas are to build up(pun intended) to higher end head amps and eventually build some very nice home audio(2 channel) for serious listening when I retire within the next few years.

Yet another Pimeta or First Pimeta in Russia :)

Hi All!

One of these days has completed Pimeta. Many thanks to Tangent's and all head-fier's.
Now I think what to build: M3 or PPA?

Nice work

Work Dynalo

I finally got around to casing up a Dynalo that I've had built for quite some time. I didn't feel like using the normal Hammond, etc., so I grabbed cigar box. After drilling/cutting all the holes, I put 3 coats of semi-gloss lacquer on it. This is built on a Rev. B dgardner board from the group buys. It uses std. Vishay-Dale resistors, Pana FM and Evox MKP caps, Alps Blue pot. Also has an Amb e12 board (v1.1 from Guzzler), Neutrik output and Switchcraft mini input jacks.

So what happened to the DAC-Ah?
