Those look like Chatam 5AR4w rectifiers! I just got one with another on the way. Very good recti, but since I also have Phillips metal base 1956 GZ34 and a Mullard CV378/GZ37 on the way, the Chatams may be kicked to the curb.

No doubt, as the Mullard CV378/GZ37 is one highly musical tube to say the least............, and then some, whereas the earlier metal base versions can be somewhat prone to being overly microphonic, so be careful here.

Yes, thanks for the info. I am eager to see if the Phillips can take on the Mullard. The Phillips is potentailly way more valuable, as I see quotes up to $650! Fortunately it cost me $25 at the Barn, but the central plastic base is missing. As long as it works, i dont care.
 
How do you compare a GZ-37 to a GZ-34?? The circuit should be optimized for one or the other, but not both. A wise man once told me that just because a tube will plug into a socket doesn't mean it should be.

As always, you're more then welcome.

But Norman, do keep in mine that Philips actually owned Mullard - Amperex - Mazda - Valvo along with quite a few other companies/factories located across the globe and in some cases, so of these tubes have quite similar sonics, so never get caught up on the designer labels on the boxes or glassware themselves - as you might stumble onto that very same sound for a lot less. And man oh man, that's one hell of a barn and find..............., enjoy it.


Peace.
 
KT-77: Nah, the GZ37 is a physically different tube to the 34 and didn't not come from the barn like the Phillips. It was Ebay UK for the GZ37, but perhaps there is one to be found in the barn, given enuff time and patience.

Mep, how do you compare? Simple, just tube roll. loL

They are similar classes of tubes and I will find out which one sounds best soon. Last time I spoke to Lukasz there are all kind of sophisticated compensation techniques to support a whole range of tubes. The circuit seems to be adaptive to a certain extent.

Indeed, L doubts it will make much of a difference due to the B7 design, but we shall see, wont we?

The metal base looks VERY different (much smaller) and dates back to 1956. Not too many versions out there, but the Bugle Boy is even dearer! The 37 is also from the 1950s, but did Phillips own Mullard all the time or only from the 1960s?

Phillips owned Pope as well, BTW!

You either missed my point or you are caught up in your own sense of humor. They are not the same tube. It's not like you are comparing a 1950s Phillips metal base GZ-34 against a Mullard GZ-34 and seeing which one is 'better.' You are comparing two different tube types that happen to be rectifiers. They have different current draws and different voltage drops. They were meant for different applications. The circuit can't be optimized for both tubes. So what you are really evaluating are the changes you have made to the circuit by swapping two different types of rectifiers. There can be no meaningful conclusions drawn about which tube is 'better' with this experiment that will be applicable outside of your experiment. As long as you determine which tube you like better in your Lampi, that's all that really matters though. Let the tube swapping begin...

Yes, MEP, that was my point, its about what better for THAT Dac, totally agree. I thought that was understood.

However, no harm in making that clear to all, so thanks for that.


BTW, circuit is optimzed for 5v/2 amps with leeway to 3 amps.
Now about the humour part…LIGHTEN UP! Having fun on the forum is part of the positive experience. Hehehe

O_oh, I'm well aware they're both different tubes! and if you DAC allows you to use either or both?, then you're in for a treat. In the end it comes down to which works best for your system and ears, as always - roll on............, that the only way to know what's what
 
The Audio Research VSI 75 Integrated Amplifier Review | STEVE HUFF PHOTOS

Yes, he loves it. I don't find the heat of the LM-219IA a problem. Maybe in the height of summer it will be different for me but now, I welcome it. The LM is a wonderful amp.

I was reading Steve's blog and it looks like he's smitten with the Devialet on his SF Futura but loves the SF Evos a little more. I miss those speakers.

But he sold the Magnetic saying it was too much heat for his room. Then he bought a Yamaha A-S3000 and said it was very close to the Magnetic in this review.

I think he had a wonderful combination with said LM-219 IA and the SF Evos, and merely wanted something different, as most guys seem more content in just buying stuff, instead of enjoy components that form a greater sense of interacting with one another in a synergistic manner - I mean aren't most building these days equipped with Central Air?, excuses, excuses, excuses.

Lest I'm wrong, shall we see how many amps he goes through by lets say next June at best..........., I mean it's fine and dandy to have the means to buy the nicer toys and all, but what about forming a system that as I'm fond of putting it " clicks ", and just ride it out until something breaks, but then I guess that takes away from the fun of buying stuff simple because one is able to afford it.

My humble little $18.900 system takes me to distant shorelines in regards to being able to enjoy my jazz collection ( 98.8% ), and the rest of my music all over the place, and plays everything I throw at it equally as responsive, in what world does one live that can't be happy with a system that doesn't dictate to its owner, what it's going to play?, or not?, to my mind that's such BS!, it's a known fact - tubes produce freaking heat................, but more importantly is the manner they produce " Music ". Some guys just don't freaking get it............., but I do enjoy sitting back and laughing my behind off watching the collectors of boxes/components try for years and years to figure this very simple shite out, and some never seen to be able to admit it's not about the music for them in the least - it's the status of being able to say - look at what I own............, instead of listen to how well matched my system evolved and how musical it sounds!.

I've never been much for humor, as I was always a very serious - uptight sort by nature, but of late I'm laughing my arse off just sitting back and counting just how many guys don't get it!, it produced to much heat my ass, if the systems " clicking " leave it along.

All of this to say what?. Joe - Mike - Jerome - Doug - Mick Wolfe - Byron, and a few other of you get it.............., if I'd afford say items as the LM-219 IA and said SF Evo ( Graphite ) with a nice table or music server, I'd be done for what's left of my days on the planet just buying music and tubes.............., but it's harder for me to just see the sort of behavior where some never seem to find happiness with what they've put together already - shite if you took the time to match the pieces together from the start then it'd have been a much simpler task.

Re-learn how to listen to the Music, listening to components be damned.

There, it's off my chest, and while some my say I'm a trouble maker by singling them out - haven't some attempted to do the same with me?, I've always tried to be the voice of logic, and see music lovers get it right, and Joe this one is meant for you.............., you've gotten it right, and seem to be enjoying the hell out what you're hearing at this very moment from what I've seen, then ask yourself this - isn't it good enough to live with it as is?, or does the need for change ever seize?.

Dig deep within, you'll know what I'm getting at - enjoy the music, enjoy life, it's a passion, not an obsession.

Try to relate to what feels/sounds right, and step away from the table with your pride intact.
 
Hello Oscar,

The above is really a wonderful post and I agree. Some of us look past what is already in front of us. I totally understand your point of view and I can honestly say you are correct. I in no way dislike anything I have now and realize that it's not the gear that ultimately gives me pleasure, it's the music that does. Sure I admit to swapping too many boxes but as I circle around what I love, that's coming to a close.
 
I thought Steve was pretty clear throughout the review as to the conditions he was dealing with in respect to his work environment and family situation that made the heat an issue. Seemed to me that he simply put his family situation first.

Hello Joe,

Dude, as my wife and kids know - I'm raw but real.

And with that being said, once again feel for you as well as a few others whom obviously can afford the better components in life - yet if you're going to go for it, at least dream big and pursue Robert Koda - Audio Note/Kondo Japan - Zanden - Audio Tekne - Tidal Audio - Tripoint - Dalby Audio Design, as I'm certain most that can afford these brands - stop for life. But as always I'd be wrong.............., and in the end, it always comes down to how the system involves you on a purely emotional level that counts, I've heard multi thousand dollar systems do scale - having the abilities of being played at extremely loud levels without losing control, and filling any given air plane hanger sized space with wall to wall sound.........., but some of these systems didn't do emotion.

And once again, reading between the lines of your last 30 or so postings, you've found " your sound " with said LM-219 IA in tandem with your SF Stadivari's, and in my mind, that's what counts. But I'm willing to admit there are times where I should merely watch from a distance and say nothing, but that's not what caring is about. Yet, I'm willing to trust you know what I'm getting at?, and more importantly why?, but know that even when I'm being silent, I'm still watching from afar.

To some extent, I get it. But as many of us know whom have been playing around with tubes for awhile - they give off extreme amounts of heat, and the bigger the power tubes, then even more so............., that's why some use solid state amplification during the warmer seasons, and pull out the tube gear during the fall/winter/early spring months - but if one has any sort of cooling?, then that's another story.

My point is there are times when we as music lovers or so-called audiophiles stumble across magical combinations only once or twice in our lifetimes if we are lucky, unless one knows how to listen to said components and only then understand the importance of synergy - otherwise we can chase this or that component based upon class ratings, which has very little to do with how things function collectively, and trash component after component, which is something I'd rather not see people do, but that's the big Brotha or Father side of me coming into play, as I can be overly protective sometimes.

The issue with heat, is not as important as to when it's comes to synergy, which was more or less my point, if so?, one might consider setting up a fan or two near the source of heat, and chill. As said rare synergies are discovered everyday - while something's play well together, some shouldn't be in the same room, not along state. But it's all subjective at best, is it not?.

Some guys start looking for their next date while they are on their honeymoon. :)
 
Since I love the LM219IA with the Strads, could I get a "better" SET and get more magic? Ha! I know. When is enough, enough. :)

Keep your eyes on me and feel free to show me the light. Now I do have a pair of Cary 300b se that I need to unbox and hook up. Thank you Steve. Can't wait to hear that magic. 15 or so watts may not be enough for the Strads but I'm sure late night listening could be fun.
