That is all!! LOL!!!

I've have many many may different tubes and the popes are my favorite

Question - are they a direct replacement for a 6SN7?

Also, can you describe what attributes you like most about them?

Reason I ask, is my Canary pre has 6SN7's. You have perked up my ears...

I would be going from the VT231 military 1950 Raytheon tubes for the linestage and I would need 4 of them.

They are 6sn7 Tom. I'd like to get a date and manufacturers code off of some if anyone has some.

Is the VT231 a direct replacement for 6sn7?
What does VT231 stand for?

F1nut

It's the US Government spec for the 6SN7GT.

Joey_V

I might have to agree

Joey_V

It is very difficult to source
I am glad @Toolfan66 found some

Yes I know, Valve Transmitting 231. It was the way they labeled their stock. Each tube had a VT VU etc. or CV etc. (civilian valve) on the British side of the pond number.
So many think they are different, better etc than the same tube the public used. Glorified stock number.

Sorry Jesse it was a trick question 😊

I should have known...lol

Some of the military tubes are much better than their civi counterparts. It just depends on what they were used for.

True. Some were super stout to withstand massive G forces, rockets and artillery pieces. Bendix and others come to mind. Still a vast majority were by and large the same tube.

Hi
Does Uncle Kev have more?

I wonder if Joey is ready to part with his stash??

I know yer a smart cookie, but I thought I’d share this screen pic. I believe it’s accurate.

No need to waste highly rated tubes if their in the wrong positions

Toolfan66

Uncle Kev is a Big Richard, Won't sell to you or want to talk to you about them if you haven't purchased anything from him that takes 6SN7 tube.

Joey is not ready to part with his, I have tried , but if not for him reaching out to me, I would not have these..

Those in the picture are mine.

Tom, I will try and make some time to post more about these. I am no tube guru like others around here, but have quite the small collection of tubes to tube roll in this unit, mostly thanks to Ivan's help and teaching, but I had to try these Popes with all of the positive reviews with these used the Cary SLP-05, not just here but pretty much everywhere people have used them in this unit. I can say without a doubt they deliver as others have said. The seller I purchased these from used them in his Cary 05.

Again, I will post more later, but real quick, one thing I have learned through the years being here is about the blackness you can hear/feel, lower floor noise, and the 3D/Sparkle attributes a system can give you as you start to move up the food chain so to speak, not always about money (it can help) but finding the missing pieces that work in your system is the goal, and as I stated these do that job..

The particular Pope tubes are Heerlen Holland made tubes. While I can't talk about the attributes of that particular tube since I've never owned. I have read it has the typical Heerlen Holland sound.

Tom, the Raytheon's you have are no slouch, but the Popes probably have a more magical sound stage and bit more air.

From Brent Jesse:

AMPEREX, PHILIPS, POPE, MAZDA and other Holland/France/Belgium made NOS: These tubes are a great balance of a clean, airy top end, nice midrange warmth, and accurate bass. They are very pleasant, clean, and musical to listen to in hi-fi applications. Most often found are the military CV1988 types, and the rarer ECC33 types from the 1950s. Detailed, sweet, and very three-dimensional tubes. The rare French Mazda has the air and sparkle of the Telefunken, the touch of warmth of the Amperex, and adds a nice bit of dynamic punch to the sound.

Holland made 6SN7's with any label are very hard to find. Also look for the CV1988 designation which is the European tube numbering system. Technically the designation 6SN7 indicates an American made tube, but they are interchangeable and it seems if the tube is manufactured for the USA, they will print the US designation on the tube even though the true origin of the tube is Euro, etc.

Pope seems to be the most common label, but again, the tube codes and where it's manufactured are more important than the label. I don't have gear than uses 6SN7's only 6SL7's so I haven't had any experience with said tubes.

You may want to inquire here. I have never bought from him, but he has a good rep. He has Valvo labeled JAN 6SN7GT that he says are made in Holland. I'd ask him for tube codes (if there are any). I have a pair of the same Valvo 6SL7's that say Hamburg on the box like it shows in his pic. Both Valvo 6SL7 and 6SN7 made in Hamburg are ultra rare.

I haven't been hunting and buying tubes for 3-4 years now, so I'm out of the "loop"

Hope this helps

Those round plate Tung-Sols are another tube I've read nothing but superior accolades about. Very very hard to get and very expensive when you do.

Original Tung Sol tubes of most variants are one of the most underrated tubes of their time. I use various Tung Sol's in all my tube gear and they are fantastic!!!

pitdogg2

Agree Brock. I've added some original Tung-Sols in 12ax, 12au, 5814 and 5751 to the stable in the last year. Both long and short plates. Once my rig gets back together let the listening sessions begin 😄

heiney9

Ivan, not to nit pick, but where did you find a Tung Sol 5814? As far as I can remember they never made one of their own. Most likely another manufacturer w/ Tung Sol label. The 5751 is bad ****. I am using a pair in my Avant.

I have a pair of Tung Sol - JAN- CTL 6SU7gty from the 40's that are superb (military, ruggedized version of the 6SL7) I use in one of my Dared integrated amps.

I'm sorry the pictures are not better Brock. It may take a few days to find ti get better pictures.

In the mean time I found these you nay like. Siemens silver plate 12au7




I bought the Tung-Sol 5814 back in April 2022 from a seller on eBay they do appear to be Tung-Sol they do have the TS writing I used to seeing. Who knows🤷🏼‍♂️

heiney9

I think you are correct. They did make a 5814. I'm just going by memory, but looking at the photo's, I remember those. Do let me know what you think of them. I'm not sure why I never picked any up.

The Siemens silver plate is cool to look at, but for me, tilted toward brightness and a bit analytical. But, every rig is different and one should give everything a try. I do have 2 pairs in the stash.

Brock the Siemens tubes I've had in the past were a little warm but yes I as you know understand what you're saying. These silver plate came with 2 other sets of tubes I bought from a member here. One set was Philco/Lansdale black plates 6189/12au7. The other escapes me atm.
Man The last two years I've been on a mission buying tubes. So so many good tubes have jumped out of the woodwork I just couldn't resist. Like you have stated it's addicting as hell. Between 6sn7, 6bx-bl7, 5962, 12 ax,au,at 7's and many many equivalents (5814, 5751 to rectifier 5ar4's, 5z, Bendix 6103, 6bq5 and 7189's black plates triple mica it just keeps going and going.
I bet I've got close to 300 tubes.

Hello my name is Ivan and I have a problem.......

The funny thing is that about a dozen pairs or more are tubes that Brock sold to others here on the forum that I bought from them when they came to market. Brock has a very astute eye for very rare hard to get tubes of certain time periods. So hell yeah he did all the leg work, research and studying, I'm buying!

Toolfan66

What amazes me is how much some of you guys remember/retain about tubes, I am not talking about brand names, it's the details that are different/variants in the same brands that some of you remember. Yes it's impressive..

I would like to try a good set of 6922/6DJ8's, but a lot of them have sky rocketed in cost like the PQ's

Man, don't bet me started again. It was hard as hell to quit. But, other than unobtainable super $$$ tubes, I have just about everything in the 12AX7 and variants, 12AU7 and variants, 6x4 rectifiers, 6SL7 and variants, and many ECC85 and variants, 6L6 power tubes, RCA black plates and St. Petersburg made 6L6.

Not a pissing contest, but to put in context I bet I have close to 600-700 tubes. I became obsessed with not only having back-up pairs, but many I have triplicates of. The other thing is, I generally can't pass up a good deal, even if I don't need them. This spills over into the rest of my life as well....LMAO.

After I quit tubes I started collecting (hoarding) barrel aged Stouts, ales, and barleywines. I have so much barrel aged beer in the basement it isn't funny. Good thing it cellars well. As an example: New Holland Dragon's Milk releases (4) proprietor's reserves every year, I have to have all of them (and I buy 2-4pks; again one "back-up"). Several other local and national breweries do the same thing,,,,,,,,,,,I must have them all.....LMAO. I do share with friends occasionally too.

In fact yesterday, as you know, was Goose Island Bourbon County Stout release day. I spent $220 on (6) bottles of 3 of the variants which are very limited. I'll get the regular & less limited variants at a later date. I spent another $100 at a local Brewery who released a series of barrel aged selections. Not to mention what I've spent at Binny's Beverage Depot in the past year....I'm afraid to look. I cut back this year too, because I have so much on the basement.

The great thing is my girlfriend is into barrel aged beer as well. So we kind of share the enthusiasm and take random trips to local and far away breweries. Audio she tolerates, but doesn't really get it.

Thanks

I have to say the "legwork" and hunt was the most fun part of the journey. I learned so much by hunting and delving into the internet doing the deep dive research. I am not kidding when I say in a sense it was like looking for and diving around a shipwreck and discovering new "gems".

Learning about tube construction and codes as a way to "truly" identify a particular tube. Also, I loved the nostalgia attached to tubes. It still amazes me I have tubes pushing the 65-70+ year mark and still operate and function like new. The little pieces of cylindrical glass that light up.....still fascinating.
