Also, been looking at the MG944 and at the Hoyt-Bedford Model 2s as more efficient "modern" options.


Either one would be a solid choice!

Very nice Steve.  Looks stunning!  The SE341.2 was a dual mono SE84+. With one power transformer, is this still a dual mono 84+?  What are the meters for?  Enough questions - I'll just wait for the details.

Great looking SET. Congratulations.

The Two power supplies in the SE34I.2 were heavy overkill.  Remember those were designed for the original SE34I that had four output tubes rather than two.

Right now, we're still at the same 40 mills per tube as before, so both channels draw 80 mills.  The current power supply is 150 mills.

So to answer your question, no, it is no longer dual mono.  

I'm in the final chapter of the voicing on it, and comparing lucid mode with one built as a classic SET just like our Zen Amp (SE84C+).  It's looking like getting lucid mode as good as it was on the Taboo may take another year or even two (like it did for the Taboo).  Triode vs. Pentode is just too much change to have the same results.  Don't get me wrong, it's impressive in it's current state, but in a serious shoot out between the two designs,  The classic Decware SET may actually have the edge in the imaging department since it's more accurately rendering the intent of the recordings.  Given that and the fact that the amp could now be bridged mono I'm likely going to abandon the unbridgeable lucid mode on this design.  After all, we still make the Taboo.

The meters are to show the bias of each output tube.  This lets you know a few things:

1) When the amp is ready to play music after powering on.
2) What the bias is for each tube
3) If the tubes match and if not, and how far off are they
4) Visual clipping indicator to make it easy to determine max power levels
5) Ongoing tube wear indicators
6) Tube failure (shorted) indicator

But mainly to let you see at a glance how close your tubes are matching and how close your amp is to max power.

...no the tubes do not have to match, especially if you have the amp configured with dual volume controls... but matched tubes mean that each channel will clip at the same point - not one side sooner than the other... and closely matched tubes preserve pristine imaging.

Genius; pure genius; and once again Steve has surpassed himself. It seems that there is plenty of room on the chassis for tube regulation.

Yes, but so far just one rectifier sighted. Smiley

Steve is really an artistic genius!

I just love the look of those meters. Gives the whole amp some sort of nostalgic look and feel.

And I also admire the functional use of those meters. This turns the amp into a tube tester for the output tubes.

I do hope that Steve will incorporate those meters for the other versions of his tube amps in the future!

Beautiful design, indeed.  Ok, it's not going to be a Lucid Mode-capable design, but I wonder how does it compare to the SE34i.2+ it's replacing in overall performance?  Any comparisons made already?  

If they sound better than the SE34i.2+, these are going to make killer triode monoblocks!

Yes, although I swore I would not build another amp without tube regulation, the SE34I.3 does not have it.  The reason why is simple.  No one is making any voltage regulation tubes today.  New Old Stock are getting harder to find in quantities.  It also skyrockets the price of the amp due to all the extra stuff that has to be done.  I'm really just looking for a nice step up from our original Zen Triode SE84C+.  For the guy who want's classic Decware transparency and liquidity but needs a bit more than 2 watts.  So far it is looking like I'll be able to offer this with a single pair of inputs and one volume control - no tubes - for $1149

Steve -

What are the other configurations you are planning for this amp and for how much?  Also, will you offer a stock set of tubes as an option?  Finally, what does this amp look like with the contemporary walnut wood base - pics Smiley

Very beautiful Steve. Thanks for posting the picture.  The functional use of the meters is sweet. I look forward to its release.

In light of NOS regulation tubes becoming harder to obtain: You brilliantly use tube voltage regulation designed to filter instead of regulate in the Torii 3 and Mini. If tube regs' dry up, do you plan to retro-fit these Amps with a form of solid state filtering (a mini power plant if you will/based on a solid state voltage regulator) - or - can a plug in be created, such as what a solid state rectifier plug in does in lieu of a tube rectifier?

Well, while they may dry up for me by becoming unavailable in quantity but I can't image that they would ever become unavailable in singles from places like ebay.  That said, in a worse case scenario I would likely replace the VR tube with a neon lamp.

I suppose you're correct Steve.....we should be able to find them on ebay etc.... (voltage regulation tubes/down the road purchase). They last forever too. It should not be much of an issue.  NO neon! Go with a black light and lets bring back the Posters too!  ;D

The release is here!  Sweet!  She is a beauty (that Rachael)!

Rachael!  I like it!  This could be love! .....Those sexy meter's.....what a vixen....hubba hubba........ Wink

Ms. Rachael?  I do believe you're trying to seduce me?!
