My space is 18 X 31 and
acoustically treated with RPG panels, tube traps and fiberglass acoustic treatment
over triple reinforced walls and ceiling. The floor is lamination beams
over steel plates to pier and beams. Two sheets of 5/8 epoxy
lamination sheets make up the floor with two inches of
concrete topped with India multi color slate.
rail system and fine textured acoustic cloth covers the work, making everything appear as a normal room with
painted sheet rock or decorative cloth covering.
The room acoustics were conceived by RBDG

Is there more to your test method or full disclosure as posted? I'm new to this tester but impressed so far. I had a KT150 power tube that was behaving in an odd way and the Hickok showed it was fine.
I tested via the Amplitrex and it showed short + partial gas problem. Not much gets by this tester.
I bought a cheap refurbished HP Windows 10 laptop and installed the software provided by Amplitrex. Now I can type in the tube number and it loads. No more scrolling through the electronic roll chart.
The HP is not yet set up to print data but it's capable via WiFi. The Amplitrex folks suggest a Brother brand label maker for addresses. That way you can print then peel and stick data to a "white" tube box.
That reads to be a great option, especially since there is an option for curve trace matching. Once I'm caught up I want to test all the tubes I have hanging around here. I have several hundred popular types, would be nice to know which are great and dispose of any that don't cut it.
Albert, I have the Amplitrex as well (about 3 years now). It's a great tester, but you have to interpret the figures. It's not just a simple reading like the other testers. I made a chart that may help you. I use the Fixed Bias setting. I use these figures Gm 90 to 100% Better than new, 80% Excellent, 70% Good (Average), 60% OK, and 50% Poor I believe the Gm which is like transconductance is what most testers give you. The Amplitrex also does Current. Enjoy Albert watch out though because friends will be bringing tubes to you or you will be making house calls. The tube doctor has arrived.
I received the Amplitrex AT1000 I ordered from Chris Terraneau a few weeks ago. I must say I am more than impressed by this state of the art tube tester as well as the customer service I received from Mr. Terraneau.
I needed to test common tubes found in high end audio but also the specialty tubes Allnic choose for their designs.
Some of the specialty tubes Allnic uses are:
Kron RS-242 in H5000 DHT phono. HL2 in H5000 DHT phono. 3A5 in D5000 DAC 8233 / E55L Magnoval base (second stage driver) in new Allnic M5000 amps.
Mr. Terraneau not only supplied Zip file with proper test data, but also built three tube adapters that allow Amplitrex testing with and without (optional) Windows laptop interface !
I found some tube errors in my system that did not show with other testers. Made a few changes and got a significant performance boost.
Of course the new Purist 30th Anniversary AC cables are the other side of this upgrade. My digital is literally better now than my analog was a few years ago (before the SP10 MK3).
I have 30th Anniversary AC on Allnic M5000 amps, Focal EM power supplies, Allnic L3000 preamp Allnic D5000 DAC and Allnic H5000 phono.
I moved my Purist 25th Praesto AC cables over to the two linear power supplies that feed Macintosh Mini and Data Tale 4 bay music storage. Hard to believe how much AC cables effect this position in the system. Wish I could afford 30th Anniversary here.
I did not think this much improvement was left in my system. If nothing else it proves it’s best to keep an open mind and experiment.
Regarding: Albert, thanks for hosting us again last night for a great evening of
music. The new Allnic M5000 amps are fantastic, as is the Air Tight Opus
After years of setting up phono cartridges, I did not believe that
we would hear a miniscule change in tracking force, but we could all
easily hear a change of 2/100ths of a gram tracking force with the Air
Amazing, and this speaks to the overall resolution of your
Thank you for that ! We all work hard to try and achieve that magical level where the system gets out of the way and you're transported directly to the emotion of the music.
I agree on the new Allnic M5000. They just keep getting better every week. I think the huge custom transformers still have awhile to go to reach 100%. That's normal for all transformers, improve with hours and these are easy to hear as they change.
Next meeting I want to move the tracking 1/100th of a gram heavier, hope to maintain the fragile perfection in the highs but improve the bass like we had earlier in the evening. Maybe even back off the anti skate a tiny bit.
As I posted in reply to Jeff, I have two substantial changes coming for the digital, Allnic D5000 DAC. If you return to hear what the Purist AC contribute I think you will be surprised.
I also want a 3 meter Purist 30th Anniversary AC for the MK3 motor controller. I know it's a bit insane but every time I've upgraded there the improvement pay off, simply stunning what that cable does for the system.
Regarding: Albert, I now have 100 hours on the Purist USB cable and it if f--
fantastic. So open, detailed, harmonically right and full in the mids.
My system is transformed can you believe just this one cable?
I agree. This last Tuesday night with friends in our audio group, my digital was working at a level beyond anything I've ever heard.
My Purist USB is completely broken in now and I found a couple of marginal tubes (and replaced them) in my Allnic D5000 DAC.
Those two changes brought a huge improvement, we listened to several cuts while spinning LPs. I ordered a Purist 30th Anniversary AC for the DAC and the 25th Anniversary that's there now will move to the linear power supply for computer and Data Tale drive bay. I think these two changes will make a startling improvement.

I will have to call Purist and let him know. I don't know if you know him, but Andre Jennings of the Absolute Sound will be coming to my home for a listen in late September. The best Jeff
Albert, I've never been east of El Paso, and travel isn't something I do much of at all anymore, but I'd sure love to hear your system. If you are ever in the Seattle area (Whidbey Island is my home), try and make it for a visit, I'd love to have you.
I have not posted in awhile but must comment on the new Allnic M5000 mono block amps that are now reaching peak break in point.
These are the best amps I've ever heard, rock solid, extreme dynamics plus warmth, combined with resolution that continues to surprise each time I listen.
Part of this magic is the 5749 input tube and second stage 8233 (E55L). The 8233 is a pentode tube (Magnoval 9-Pin)capable of driving efficient speakers it’s so powerful, yet it's used to push the (8) KT150 tubes into territory where they perform like you have never heard them.
The M5000 is a CNC machined package that's beautifully crafted and hand built right down to the custom transformers that Allnic owner KS Park builds himself.
Last, this amp gives control much like top tier solid state, my 16" woofer has never punched like it has since this amp went into my system.
My Focal speakers are 95DB efficient, so it's the M5000 overall design and execution that brings this new level of performance.
I had enough power with my 200 and 250 watt amps but this is another animal and deserves credit for pushing the limits beyond what I thought was possible.
Albert I switched cd's on jriver with my computer and my DAC lost the signal and a terrible digital noise was heard through my speakers. It blew both of my tweeters. Purist and Bricasti don't have a clue. I hope this does not happen again. 1100.00 for new tweeters.
It breaks in faster than earlier version Purist and faster (if memory serves) than my AQ Diamond.
Or maybe it's just so good out of the box that I quit listening for break in and started enjoying the improvement it brought to my digital.
Direct answer to your question, I think after the first 50 hours or so it's pretty much there. I've had mine for many months and don't even think about it any longer. Just punch up the software and listen.
Reminds me, I need to upgrade to this latest version JRiver.
Swamp, great to hear from you. Glad you bought the Sony A6000 and it was a hit with your wife.
I love mine and actually use it more than my pro Nikon due to weight difference and the fact most people cannot use all the detail and image size the Sony produces.
I lost my mind a bit and opted for the Sony Zeiss Vario Tessar, E 4/ 16-70. It’s a fantastic lens. Sometimes it pulls off color and shading that resembles my old Hasselblad. Of course Hasse was all Carl Ziess.
The only problem with the Zeiss lens is it’s in the light path of the build in Sony flash. So if you must do fill light, it’s back to the stock lens.
Hey, Albert- You may recall that a while back I asked you for recommendations on an advanced amateur digital camera for my wife. Well, I took your recommendation and got her the Sony a6000. She retired recently and finally got a chance to give it a whirl. The pictures have been fantastic. So far, she's been using the various scene-specific auto modes and we are both very pleased with the results. Once she gets deeper in, I'm sure she'll be even happier.
So thanks much. I hope you are well and if there is ever anything we can do for you or your family, please don't hesitate to ask. Despite all of the internet trolls and scammers, this cyber-village of ours is an island of community in a crazy world.
