Monbrison Versions

I would like to know what a telefunken EL94S is, cant find anything on it.

Related question: when did the Giscours switch from WE 349a tubes to the CV391? Thanks!

[countingbackwards]

My research indicates that the Giscours switched to CV391 tubes in ~2009, having been produced in the latest 349 version from 2004 to 2009.

Thank you. Any insight into roughly how many of each were produced?

No idea how many of each were produced…my guess would be that there is a similar quantity of both types of single-box Giscours that has been produced given that each has about a 5-year production life. (We're pretty far of topic here in a "Monbrison Versions" thread…).

Having heard a couple of Monbrison's, I would be hesitant to presume that the "version" of a Shindo product is all that important. They can be quite different or similar in internal construction, regardless of which "version" they are. The "versions" seem to be aligned mostly with shifts in primary tubes, which are only part of the package, given that capacitors, transformers, etc. can change without a new "version" being declared.

What I have deduced is that as certain tubes have become scarce, the quality of the rest of the unit has improved to be able to get comparable or better sonics out of lesser tubes. A good example of that would be the D'Yquem's, which while I haven't heard, some people whose ears I trust have really, really liked - and they use bog-standard current production tubes. As do the CC80's, which sound as natural as any KT88 amp has sounded to my ears.

All that to say…given limited supplies of certain tubes and other parts, Shindo probably needs to be a little better as designers today than they were 15 years ago. The good news is - it seems like they are. Thus justifying the higher prices of recent years.

Hues, are you certain about the ECL84 tube being equivalent? Have you tried it? The ECL94s seems to be non-existent.

[Hues]

No, not certain at all...in fact, I'll edit the post since I can't find any substantiation anywhere.

Indeed, the ECL94S does seem to be non-existent. Apparently the ECL 84 cannot be substituted for the 94S. Cheers -Don

E= 6volt heater. C= gain triode. L= power pentode. 90 series is 7 pin glass button mini base.
4 is 5th iteratin in that series.
An ECL94 according to the DIN typing code would be a 5th iteration 6-volt-heater gain-triode-plus-power-pentode on a 7 pin mini base, an very unlikely specification. I think an ECL84, on a 9 pin glass button mini base, would be more likely. ECL8# series were very common in the tube era as one could make a light duty stereo power amp with just four of them plus a rectifier.
