Jeremy, When I get the SA67, I can come visit you at the studio, and we can do a comparison with the Neumann U67 there. (Jeremy is the senior engineer at the world class Barbershop Studios in New Jersey). Vincent, you can come by my place to shoot-out the Stam with any of your mics. Sounds good to me. Jeremy’s U67 is so nice.

stamJosh, what's the NOS tube you use for this upgrade. I put a deposit on the mic this weekend and I'm considering the upgrade.

I'm getting excited about this now. Stam's just introduced his new version of the 1176, and it's a really cool update to the design. He's getting better and better at bringing cool options to gear heads like us.

Been drilling the PSU's and mounting the PCB's
We will get there, 47's and 67's start shipping this month
It will be a while until we complete them all, many orders and these are hand made one by one.

Stam said, "many orders and these are hand made one by one".
That's really cool. It gives me much more confidence the people building it have tested it before shipping and that it sounds right. I have a personal belief that something made with love and pride carries that energy in it.

Hey Guys There are two versions of the SA-67 available. Standard and NOS The standard has the Heiserman HK-67 capsule, Cinemag transformer and current made EF86 EH tube. The NOS has the Heiserman HK-67 capsule, AMI BV12 tranformer and NOS EF86 tube. I also added Allen Bradley Carbon resistors. The differences are small, both options sound very good with the NOS being a tiny bit closer to the U67 sound, but minimal. The reason for the price difference is due to the AMI BV12 being seven times more expensive and that in order to get one good EF86 NOS tube working without noise I have to buy at least 3 of them. It is also much more work as I need to build, burn for 48 hours and re test again to make sure it will not present noise afterwards while the current ones are good out of the box. The NOS EF86 is also much more expensive. I would say one get's you 95% there while the other get's you 98% there. Small differences but I know some purist will go for it. Hope this explains it. Thanks Josh stam Josh, third time I'm asking this question ...fourth time if you count the email I sent to your support address... what NOS tube is used in the $500 upgrade to the SA67?

Are the standard ones being made first - shipped out first or are the upgraded ones being made first - shipped out first? Or are they being shipped out as per first ordered date? Whats the system so i know when to put the rest of the moeny aside? Thanks Has anyone received theirs yet?

I'm starting to wonder if the NOS tube in the SA67 is some kind of Chilean government secret.

I didn’t get a reply to my email to Stam Audio either FWIW.

I am guessing the standard will be the eh86 tube. Worst case scenario just buy a nice ef86 or a ef806 from .bowie and it shall be good. Is this a reasonable solution? Or is it not as simple as this? I have been known to be wrong about Electronic stuff before.

Not to make matters worse, i was reading an old thread from Oliver saying that the failure rate (now we are talking about Olivers high standard here) for new ef86 tubes was 100% . And that in all good conscience Oliver could not use current production ef86 tubes. Klaus was also indicating that he felt this was the case in his research. These threads were about 5-10 years old from memory. So i am thinking i will happily use whatever new tube is in there and just upgrade it somewhere down the track.

Well if it's a NOS tube it can't be a current production I assume. Anyone who's sourced old tubes knows you must settle for whatever low noise brand you can get. That's probably why there is no possible answer to your question. Good quality, quiet NOS EF86's are getting more rare these days.

I have been known to be wrong about Electronic stuff before. I think the question has more to do with paying extra for a NOS tube. The $500 jump to the NOS version for upgraded caps, transformer, and NOS tube is all fine and good, but if you could make that upgrade $400-450 and then just order your choice of NOS tube from Bowie, then why not? Now if we know what tube is being offered we will know if we are going to want to drop an additional $100-150 on a different NOS tube. Having played around with a few tubes with my MK67 I can tell you they do make a difference.
Heck, even the guys on the U67 reissue thread have said how replacing the stock tube got them even closer to the originals.

For the sake of being complete, here's stams answer from another thread. stam Weeks ago I asked for information on what NOS tube you use in the upgraded 67 mic. I asked the question in this forum several times in posts where I tagged you so you'd seen them. I even emailed your company for the information. I still haven't gotten an answer. Any EF86, Valvo F80, Telefunken EF86, Philips, whatever I can get

I understand the interest in the tube but for the sake of conjecture aren’t people likely to eventually order a tube from Bowie anyway: I know I probably would:)

It would make the upgrade closer to $400-450 instead of $500 and you could take the extra $50-100 and just buy the tube you want.

I have already started buying some recommended tube options in anticipation. But yes Bowie is definetely the backup source.

Vincent, yes that is a fair concern. Not that it has been said but people are implicitly referencing substitutions and cost savings, so what happens with the warranty, in fairness to Josh ? If he hasn’t tested the mike with every possible tube how does that work ?

If he hasn’t tested the mike with every possible tube how does that work ? That is a totally valid argument. Josh is most likely tweaking each mic to work with the tube selected and get the sonic quality he’s looking for. That’s the nice thing about getting a hand made piece. Josh is offering a cheaper tube with the standard version though, so you could save money on the upgrade by just getting that “stock” tube and still getting the other upgraded components. That’s what I was leaning toward. It doesn’t really effect me, as I haven’t ordered one. However, I love the U67 sound and look forward to hearing what everyone has to say about this piece. I have always been impressed by the clips I have heard of all the Stam products. I’m also looking forward to trying jtc111’s when he gets it later this year and putting it next to the TLM67 and the BLUE Bottle Rocket II w/B11 Cap (which I think has a really good 67ish sound). Jim ordered the upgraded version. That may be one of my videos in the future.

Personally, I would want a known, working backup tube to go with any mic. That way if some random tube goes noisy on you, you have an instant solution.
