You can also upgrade Stellavox SP8 to SM9 and for more information now you can send an email to Jean Michel Simonet.

Jean Michel gives you great support.

I should thanks him for great job.


Stellavox Tape machines like SM8 have good analog transformerless output stage and you can enjoy the sound.

Jean-Pierre Gurner and Jean-Michel Simonet (development and production engineers at Stellavox since 1968) take over the machinery and service facilities for the tape recorders.

Monsieur Simonet http://www.audioprojpg.com/

A refurbished machine will cost around $6000, so reach into your pocketbook!

If fully up to spec, the Stellavox will offer the best sound in the world.



Yes, Mr. Simonet is in business and does service, parts, and modifications on Stellavox machines. Jean Pierre Gurtner died in 2018 and formerly the website that is up now was his website. It is the deceased expert Gurtner who did not update the website for some time.

Stellavox is superior sound to Studer but it is not a studio machine. The Stellavox SM8, which I use here, is outstanding for stereo captures. More detail, more pure analog tone, and better sound than Studer which I have also used for many decades.

Inquire with Monsieur Simonet about what is available from him. You can always buy a Stellavox SP8 and have it modified to run as a master machine, SM8. SM8 runs at 15 ips only.


Transport of the Stellavox machines is not as gentle on the tape as a STUDER A-80. It will not harm the tape but start up is not instant. Once stabilized there is vanishingly low wow and flutter. Use the Stellavox ABR accessory to run 10.5" reels.

In the studio, a better use for the Stellavox would be in mastering to tape. Play your completed program into the Stellavox for ultimate sound quality.

All Stellavox machines are made for capture, not for post-production.
The STUDER A-80 is a Buick. The Stellavox is a Ferrari.
ean-Michel Simonet is actually a part of the new legitimate Stellavox company, founded by Schertler. Jean-Michel Simonet will be responsible for the small recorders, which is what he has done for the last 30 years.

The founder of Stellavox, Georges Quellet is also with the new company. He gives important input for new developments, despite his old age. Because of covid, they haven’t been able to meet in person recently to discuss developments and plans for the future.

On the official Stellavox website there will be a new category “Behind Stellavox” added to the home page very soon but it is not quite finished yet…

Please check in a few weeks to see the news on the Stellavox home page. https://stellavox.swiss/

Interesting news! If indeed Messrs. Quellet and Simonet join, that would go long way to adding value to the new proposition.

Schertler certainly has the monetary resources to back whatever they decide to do with the "new" Stellavox.

However, making input modules for the very few Stellavox TD-9 machines sold world wide is very small potatoes. Likewise, the harebrained idea to make an expensive new Swiss analog mixer based on the poorly reviewed Schertler "ARTHUR" mixers is a dead end. Majority of engineers today buying budget digital consoles like Yamaha, Midas, and Behringer. These consoles offer excellent audio performance far outclassing what Schertler has offered with its noisy mic preamps (EIN of 122.5dB.)

I do not yet consider the company to be legitimate.

The Schertler sponsored website states that the Stellavox website was created "for entertainment purposes."

I used to work for the US distributor for Stellavox back in the GLORY days. I worked with Georges Quellet.

I don't understand the comments RE: SP 7 recorders and maintenance.


Any mechanical piece of gear requires maintenance and Monsieur Simonet can do it for you. He is the only one I trust. There is NO credible Stellavox service in the US.

I never recommend buying a specialist piece of gear on eBay or sight unseen.
Don't buy an old SP7. Instead buy a refurbished SP8 or SM8 from Simonet or similar.


When you buy an old recorder from the 1970's, all the parts and electronics need to be replaced and it is a dumb idea.

The resurgence of analog tape recorders has brought rank amateurs into the marketplace who do not understand what they are getting into.

A refurbished machine will cost around $6000, so reach into your pocketbook!"

Well, I am sure these people will provide excellent service, but I wish the tone was less assertive. Certainly Charles King provides exceptional service in the US.

Oh come on. The Studer is at least a Porsche GT.

I have not compared X vs Y vs Z tape machines and The text (post #5) about comparing studer vs stellavox is from "Plush" in another forum.

What is interesting about Stellavox is it has simple minimal descrete output stage without any transformer.

Single-ended only. A well designed transformer is a wonderful device.

Just saw this thread. Where to begin?

I was introduced to the Sp series of recorders by rich Brown maybe 25 years ago. As most of the units were "older" and required some kind of service, I began doing how to do that while acquiring some of the necessary spare parts. Over the years have repaired/upgraded many dozens of units. Also tried my hand at recording - failed miserably - it's an ART that requires MUCH MORE time and effort than I was willing to put in - but that's another story.

The Sp series of recorders, when "up to snuff" are wonderful machines. As Amir (and many others have said) they sound great, for both recording AND playback. I've had a few opportunities to compare their sound to the "similar" Nagra's (4S), and the Stella's are much better.

The Sp models were the 7; 8 and 9. Main difference with the 8 was the re-engineering the battery compartment to allow for fifteen AA cells versus the twelve cells in the 7 - and doubling up on the drive belts to transmit greater torque. The higher voltage allowed for more headroom. Otherwise the electronics remained relatively unchanged. The earliest 7's suffered from VU meter failure and certain parts in the supply and takeup mechanism's needed "beefing up" for more durability. Good news is that all the upgrades can be retrofitted - maybe not the extra batteries. Do have to say that there is clutch in the supply mechanism that has a 100% wearout rate - evidenced by a noisy/clickling sound during playback/record, otherwise the machine ruins perfectly quite. Bet that every machine on Ebay needs the clutch rebuilt.

Most of the Stella's I've ever seen are in good to excellent shape, and I don't remember ever having to replace any heads because of wear - have had a few open playback heads for some strange reason. Stella originally used Bogen (German heads) which sound Very good for record and playback, with Wolke(sp?) erase heads. Later units went to Nortronics heads for playback.

Everybody seems to have to have the M version. I don't happen to think so. Main feature of the M is butterfly R/P heads (and a higher bias/erase frequency). Early butterfly's were Bogen; later were AMG. Suggest finding a 7 in good shape; and when "up to snuff", go down the road really happy.

ABR's are hard to find, as not many of them were made in the first place. Don't know if the Swiss guys with the parts have them now.

Probably have missed a few things - so more later...

Charles

O yeah - Foxbat had me work on his machine - believe he's pretty happy with it

Yes, absolutely happy! Charles does super service on these models.

I have the ABR, but it is, frankly, a half-assed solution, unlike the Nagra's motorized QGB... but of course you get what you pay for, with QGB being many times more expensive.

I agree with Charles. My Stellamaster SP8 was the cleanest record/playback sound I have heard out of a stock machine.

I did not find any Interconnect cable for connecting Stellavox SM8 to my Pre-amp and finally I ordered custom made Acrolink Mexcel DA3100 DIN (Stellavox Left Side DIN Output) to RCA Cable (two RCA for stereo channels - Preamp side).
