We have launched two new tube adapters! Customers request our adapters as our configurable 6SN7 to 12XXX has become quite a coveted item. It gained its reputation because our build quality is outstanding, pins are tough as nails and our PCB work is top notch - IMO the best adapters made!
- ADAPTS 6GH8A TO 7199 ADAPTER FOR DYNACO OWNERS AND OTHER
- ADAPTS 6SN7 TO 5670 / 396A PINOUTS
Have a look at this eye candy!
As always with anything that anyone designs and is passionate about, revisions come over time. Our revisions are very clear as you can see our PCB revisions right on the boards! Others are hidden under a lid and kept hush hush. So before the latest wave of PCB rev hysteria hits - Thought I would tell you all about them so you have the facts vs. speculation. Here are the details that will matter to you:
Ember 2.0 board rev:
We have a new version of Ember that will start shipping on or before the 1st of May! Here are the facts
- Supercharger will now be built into ember and will be the default tube heater powerplant. With this comes a price increase over the base model Ember which will go from $324.99 to $349.99. However this means a price REDUCTION for persons planning on purchasing a supercharged Ember! Old supercharged price was $364.99 / now $349.99 (as stated previously). We passed the savings along / $15 cheaper. This means hard to power tubes like 6n6p, 6n30p, some 6sn7's... all are powered with ease just as the supercharger offered before!
- Line out disconnect for the pre-amp out is now standardized on Ember (can be changed via two solder jumpers) This means when you plug in headphones, the line out is disconnected
- Like our other designs, a quick change input attenuation module is now on-board. This means you can change the input level which gives you infinite adjustability vs. fixed settings when it comes to gain - further resolving volpot range issues with different efficiency headphones. There are also two quick change jumpers to change between default fixed gain and the customizable attenuation module
Many will think OH CRAP, my rev 1.0 Ember is obsolete! NOPE. Ember 2.0 features the EXACT same loved sound as Ember 1.0 With just a sprinkle of changes that we have been wanting to implement. The changes are subtle enough we considered just a .1 rev bump but with the addition of the SC on-board, it was felt the 2.0 designation was warranted.
Polaris 1.2 board rev:
- This one was simple. We just added a pair of resistors which prevent the loud pop when changing from low gain to high gain
Starlight 1.1 board rev:
- We added an extra output resistance setting / total of 3 to better suite a wide range of headphones
- Stainless thumb screws will be default as of May 1st
- Starlight also gets an input attenuation module! Now you can build up or order in a gain module to suite your headphones / have better range on the volpot
Sunrise / Horizon 3.1: - Fixed a couple of board mods that we had to make manually before (noise reduction mod and a change to the LED)
I will be updating photos of all the amplifiers soon. I changed up the looks of all the chassis and everyone that has seen them agrees, we upped the sexy! They are slightly larger and in the same style as our CNC'ed chassis (which I will also be doing a photo shoot of ASAP!
From customer feedback, we have decided to stop sending manuals on CD in the package as the same manual can be downloaded right from our site. Customers and friends told us in most all cases, the manual for their amplifier had already been downloaded before delivery so the CD just went in the trash DOH!
Manuals for the new revision amplifiers are being uploaded this week one at a time as I finish them up. Stay tuned!
Everyone knows that we love vintage tube testers, and one of our favorite testers is the B&K 747. We dig this tester so much that we decided to build a parts kit for it so that the tester can be easily / properly restored with HIGH quality parts. Get rid of that junk - cracked phenolic PCB and all of the old, drifing carbon resistors and leaking or blown caps. Add in our high quality 2oz copper PCB with gold wash, gold plated quick connects, outstanding component choices and the tester becomes serviceable without having to de-solder countless wires. Overall, an excellent kit done right! Pick up your kit in our new Tube Tester Projects section!
Wow... We are already in November and 2015 is almost gone! It has been a fantastic year and we have had the pleasure of meeting a lot of amazing customers with amazing setups! So many of our designs are being enjoyed worldwide that it is an amazing feeling - one that is hard to describe when something you have poured your all into is being as loved by others as much as yourself.
We do have some new goodies in the works we think you will dig. And some old items getting wrapped up!
- Final testing on our linear is just about complete. This seems to be the pushed back project of the century as we always find things we want to do before this. But she is real and actually on my bench :) Frans worked some of his voodoo on a few hurdles we faced but overall I am VERY pleased! More info to come, she will be released for pre-order before the end of the year which is great!
- In-line filter assemblies are coming our way! Something everyone has been asking for. Stay tuned :)
- Solid state / remote power switch for our amplifiers. Will let you have a power switch anyplace on your desktop
As always, feel free to email us anytime to discuss anything! We always love to hear from our customers!
We have recently released Ember 2.1. Before you panic and think your Ember 2 is obsolete, don't! The change was minor. In short, we changed up the input jumper configuration to offer a couple more options with almost the same amount of pins (Fran's clever dice jumper layout).
Now let me explain why we made this change. We recently added a resistor to the whole product lineup that further killed scratch in the volpot as certain tubes / random tubes had micro levels of leakage that were higher than others. This could cause scratch even with the input caps in-line. This resistor further eliminated this and took it to the next level. However it had a side effect on a handful of tubes such as 12at7's or 12ax7's that could be heard in high efficiency IEM's. The result was a slight but noticeable increase in background hiss. (The joys of being compatible with such a wide variety of tubes HA!) So Fran's suggested a simple but effective 4 way dice jumper to give our customers more options on the input side with Ember for micro tweaking capability. Thanks to a great customer Eric for helping spot the combination of things that increased hiss with his IEM's)
Before: You could either have the input capacitor in-line or bypass it. Many Audiophiles like this better even though it can cause a scratchy sound in the volpot as a micro amount of DC makes it through
Now, we have 4 total settings:
- Through cap + resistor = default setting / results in ultra low volpot scratch with certain tubes that are a little leaky
- Bypass only the input resistor = This can lower background hiss on certain tubes like the 12ax7 / 5751 or 12at7 with ultra high efficiency headphones or IEM's
- Bypass input capacitor = Some purists do not like an capacitor on the input side so we give this option to eliminate it. Usually results in volpot scratch with most tubes but does not hurt anything
- Bypass the input cap AND resistor = For the purist that wants to lower background hiss on certain tubes like the 12ax7 / 5751 or 12at7 and not have an input cap
Oh man that sounds so complicated, what do I do? HA! It is actually simple as it gets like most of our settings. Changes can be made in REAL time while listening to music or background levels. Literally move a pair of jumpers and listen to the change or lack of change. If you like it better, leave it. If you like it less, change it back. Yes, life can be that simple! As with ALL settings on our designs. There is virtually NO right or wrong. Just what sounds best to your ears and THAT is what matters.
In other news:
- Polaris, Sunrise, Horizon and Ember CNC chassis are back in stock and rolling!
- Linear Power Supply chassis are now in the works and production boards are here. More to come soon on this beast!
- More tubes being loaded onto our facebook page tomorrow 3-19-16
- Looking forward to an office move this August or September depending on when things are completed. More room to expand and larger shop!
- The worlds supply of the beloved DIP-8 LM4562 opamps has come to a virtual end. They were discontinued which seriously risked the life of our budget monster Project Starlight. Have no fear - we have secured and made a large enough investment that Starlight will sing for the foreseeable future with our choice of opamps!
Our Project Kameleon in-line filter is shipping.
- Kameleon is a powered in-line EQ that accepts modules custom designed for individual headphones. Issues with the headphones response are addressed - corrected. This takes already good headphones to the next level!
- Quite a few Kameleon modules have already been designed for a large qty of headphones - Feedback is outstanding! Once you hear a properly corrected headphone, going back is almost impossible.
- Kameleon has a power loop / output so you can use your stock G1217 amplifier power supply to power both Kameleon and your G1217 amplifier. The power switch on Kameleon will turn your amplifier on and off too!
- Kameleon is available as a stand-alone product with its own power supply. This way - you can use it with ANY source / amplifier combo you like!
- Kameleon is an active filter and NOT software based
- The filter module can be totally bypassed without industry trickery (circuitry to make a bypass sound worse without the filter). This way you can truly A/B a filter module
To learn more about the in-line Kameleon filter, please visit our site and DIYAH forum!
We now have a production -20dB and play attenuation cable for sensitive headphones!
