A while back, I put together an AMB linear power supply kit for my Remedy Reclocker to replace the factory supplied wal-wart switching supply. AMB supplies some of the parts with the kit, while others (including the chassis) have to be bought separately. I was quite pleased with the sonic results, but not tickled with the inexpensive box I bought for the chassis and my ensuing amateur-ish attempts to configure it. Link below to the original effort. Saw the box pictured immediately below on Ebay, and thought it would be nice to have a box that looked as good as it sounded. So after transferring the guts from one box to the other, I'm pleased with the result. I'm short one silly faston connector due to the switch location necessitating a longer wire run to the IEC inlet, so I haven't fired it up yet. Don't expect any sonic change, but at least I'm not embarrassed to look at it now. :)
Nice job, bcowen! That's the same high-quality enclosure that my Zerozone 100VA PSU features. BTW, have you considered placing a set of your carbon fiber discs (with indentations for spikes) implemented as coupling discs under the tips of the brass cones?
Thanks Duster! I hadn't thought of the carbon fiber discs, but I'll give 'em a try. Thanks for the suggestion. I have one set under the Art Jota amp where they offered some nice improvements over the stock footers -- more definition in the bass, better imaging (which is a challenge with my speakers so every improvement there is welcome), and a more relaxed treble presentation that's especially noticeable on less-than-great recordings. All in all, one of those tweaks that offers sonic goodies way more than the cost would suggest. I have the other set just sitting that I was going to try under the DAC but haven't gotten around to it. Maybe I'll try them under the power supply first...
Another benefit of the 10mm x 40mm carbon fiber disc is good dynamics, especially if a *low-mass* Herbie's Audio Lab 40mm Thin grungebuster Dot with optional adhesive-backing is affixed to the bottom of the disc. BTW, I found the most profound placement of the 10mm x 40mm carbon fiber disc with a Herbie's Audio Lab 40mm Thin grungebuster Dot with optional adhesive-backing affixed to *both* sides of the disc, is between the top plate/pillars of a speaker stand and the bottom of a stand-mount monitor. It makes sense, since the substantially large carbon fiber composite disc provides excellent vibration wave blocking and self-resonance dissipation, while the *low-mass* Thin grungebuster Dot with optional *low-mass* adhesive-backing affixed to *both* sides of the disc provides a notably uncolored/linear sounding mild decoupling action.
Extremely well done, even to the point of I'm to assume directly connecting your DC cord internally......, now that's creative thinking.
Thanks! Funny, I spent quite a bit of time looking at DC connectors when I put the first box together, trying to determine which would be sonically transparent and easy to cut a hole for. And then it dawned on me that the best connector was no connector. Probably not the best option for a commercial product, but works in the DIY realm, especially for a dedicated supply.
Have you used it yet ? How does it improve the sound?
Changing the cable doesn't look like it would be too hard.
If you subbed R10 with an adjustable Trim Pot you could adjust the voltage out, and be able to use it with different components.
Regardless, great job!
I've used it in the previous chassis. This is just a cosmetic upgrade. :)
It offers a decent improvement over the inexpensive wal-wart that came with the Remedy. More ease in the upper frequencies, less "digital" sounding, more low level detail. More of what the Remedy itself brings to the table. The difference wasn't huge...more along the lines of stepping up a level with an interconnect from the same manufacturer. But it was fun to build, and for the cash outlay involved was well worth it (to me).
A trim pot would be nice for different voltages, although it may require a different diode as well depending on the output voltage. As I'm needing 9 volts, I leave R10 unpopulated. Still, it takes some diode swapping to get the right output voltage...guess there's a lot of tolerance in the actual value of those things. Good thing they're cheap. :)
Your welcome......, and taking into account how your project turned out appearance wise, it seems that if you wanted to with the attention you've paid to detail you'd actually offer your services on this particular build to those seeking LPSs.
But as yours does offer an extra sense of flare compared to the Chinese builds, it's certainly something I'd consider looking at your craftsmanship......, just a thought.
Thanks for the compliment and the thought. May be one of those retirement "jobs" to look at (which isn't too terribly far away for me). I can't remotely imagine just sitting around. I hate golf. I've already traveled. And being a Wal-Mart greeter is not at the top of my list...
I have my late father-in-laws planar, jointer, radial arm saw and table saw sitting in storage in Oklahoma. He wanted me to have them as I used to pal around with him in his wood shop when I lived there. Been a while since I had my nostrils clogged with sawdust, but I'm sure it would all come back. :)
What audiophile tweakers need is an affordable one-off fabrication service. How about that for a semi-retirement gig? I totally miss having a garage full of tools after moving into a condo complex.
Then I'd just be doing more of what I do now. Doing stuff for audio would be a lot more fun though. :) Unfortunately the cost of the machinery needed would be prohibitive, even if bought used. Still, food for thought...
....you could always go back to the high-paying world of audio reviewing.
LOL! I never actually added stuff up, but I'm pretty sure that paycheck didn't even cover the cost of the electricity consumed.
There were other perks though...I really miss going to CES. Reviewers get treated like royalty. :)
Once again, you're more then welcome. Being the sort whom would electrocute trying to solder two wires together, I'm able to spot creativity if nothing else. And taking into account that there are only two stateside companies actually making LPSs ( UpTone Audio | Wyred 4 Sound ) it'd once again make prefect sense to consider said venture.
Looking at what Kenny Lau is charging for his over on CA, would clearly give you an ideal of what's what, and in doing this as an extra means of sharing your wares would in fact be what your late father-in-laws had intended.
If you ever decide to follow up on this quest? ( or in my case request, as I can't justify those LPSs approaching $400 - $450 ) by all means do put me into your list of perceptive buyers......., once again very nicely done, with what looks like a very nicely thought out design concept which internally looks much much cleaner then anything I've seen from China short of that ZeroZone version Duster mentioned earlier on.
I'll be watching......, with fingers and toes crossed.
WAF factor is now tooooooo high! Please re-adjust... :)
The spousal unit asked me what in the world I was building this time. "A power supply," I replied matter-of-factly. She gave the usual eye roll and walked off. I should have said it was a sex toy or something to determine if she was even paying attention. :)
