Indeed, the transformer-derived line level output of the Mini-Torii is the best I have found in terms of integrating a subwoofer.  The gain and impedance relationsip just fits the two very well.

I honestly know but a small fraction aout this than many, Fireblade.  I've learned a bit from focused research and reading, and what I have learned about myself in the process is that, the more I get into it the more I realize how much I don't know!  I have books about audio desgin that were written such a very long time ago, and find the extense of understanding back then really sort of mind boggling impressive.  So much of what is being done today has mostly been done before, yet the Mini-Torii, which was inspired by an old instrument amp, has traits incorporated by an insightful designer.

Nice bike, by the way!

And so, the little Torii only gets better, teaching a very expensive pair of 2A3s just how good a single-ended amp can sound.  I had called and talked to Steve about a very minor rolling off of high frequency information, and while talking with him I suddenly remembered -- a bit to my chagrin -- the HF attenuator.  And this was indeed the issue.  A flip of the switch brought back amazingly clear and clean highs. Just a really superb amp!

We share the same 2nd passion!  I had an R6 years ago, sold for something more my age and speed, Cagiva Gran Canyon, and then sold that and saved for my dream, which has a boxer twin

You will love the Mini Torii.  In a short mount of time, it has distinguished itself very positively against much more expensive, not to mention much heavier amplifiers.  The first watt of this little gem is one heck of a civilized and refined first watt.  Kind of shatters the notion that the key to good sound in a valve amp is directly related to the size of its output transformers.

An R1? Fast!  Scary fast!  Be Safe!

I know many of you have done some tube rolling on the Mini T.  I woke up from a short Sunday afternoon nap (a rare luxury!), happened to glance over at my c. 1930s Philco Radio, and remembered it uses a pair of 6F6 outputs.  Thirty seconds later they were installed in the M. Torii.  Well, I have to say that it is really fine sounding!  I find the 6F6 sharper and very clean and clear, where, while still excellent, the 6V6 somewhat warmer, softer.  Next went in two of the four 6L6s that are residing in an amp I bought to rebuild into a dedicated stereo amplifier -- a 1950s vintage Baldwin organ amp.  Such an awesome and flexible little amplifier!  I do prefer the 6L6 or 6F6 types, particularly the latter.  So, this was just to share.

Some don't care for the 6F6 type, Fireblade.  It is an older, just very neat as a vintage application, and the pair I happened to try had, for lack of a better way to describe it, a sort of purity of tone and clarity, at lower volumes, than did the particular 6V6s used before.  Also tried both 12au7 and the 12at7, and find the 12au7 not only quieter (I very much dislike background noise) but more delicate and resolving -- this with several CDs of classical guitar music.  For higher volumes and/or heavier music genres with more bass laden passages, a combination of 12at7 and perhaps 6l6 outputs might be really outstanding.  Have fun!

If there is one thing I have learned about all of this is that there is not right or wrong or better or worse that can be applied universally.  This includes not only input and output tubesin the Mini Torii, but every aspect of listening to music at home.  It is fine for us to share our (highly subjective) impressions of components and elements of those components.  What is simply impossible is to apply or impose those impressions on one another as ultimate 'truths' in all instances.  Our hearing and processing of sound is just to individualized than that, regardless of the fact that the same anatomical structures are used.  Our response and opinions differ as much as preferences of food, beverage, art, or anything else.   The only mistake you can makemis try everything you might be interested in as far as valves for this amp, and based on that, perhaps select what seems to work the best in most instances.  I have a great aversion for statements and declarations I have found on forums where one individual will criticize the choice or tastes of someone else simply because thay aren't aligned with his or her own.

So play with your amp and enjoy the search!  It's ability to be personalized is one of its virtues -- and by all means continue to have fun in the process!

FB,

Our amps will be brand new and I plan to run it stock until it settles in.
I will go real slow rolling tubes until then. O.K. I'll likely plug in a pair of 350B, after 100 hours or so.

"The only mistake you can makemis try everything you might be interested in as far as valves for this amp, and based on that, perhaps select what seems to work the best in most instances"

The above can be a mistake because you will go broke and crazy...not necessarily in that order. Don't ask me how I know that.

Mini Torii chassis has beem removed from wooden bass, and headphone jack will be installed tomorrow.  I must credit Decware for a very nicely wired little amp, with very clean lead dress and classisc ground buss.  textbook soldering, and quite a bit better than what I've seen from, surprisingly, well known companies.  Truly nicely done, and that makes me happy.  I've always used carbon comp resistors in grid stop positions, but the metal films off the wiper of the volume controls are doing just dandy.

In case some of you might ne interested: I know of an extremely quiet, tube rectified and regulated amplifier that is DEAD quiet with my Grado phones.  Wow.  I have a couple of others that are quiet, but the noise floor on this thing is just really amazingly low.  The gain seems perfect for the headphones.

I'm referring of course to the Mini Torii, and comparing it to an otherwise very highly regarded and well reviewed single ended amp, the Moth Audio si 2a3, which I still very, very much like to use from time to time with Klipshorns and Lowthers.  I'm sure some of you had the phone jack installed, but I didn't so will get that done tomorrow.

Thanks for doing such a nice wiring job on our Mini Torii!!! At times in the past I have cringed at work I have seen inside tube amps, despite the super snazzy looking exterior.
