Tube integrated amp less than 12" in depth?


I am looking for an integrated tube amp that will fit in my office. I play CD's on an Underwood mod 1 Jolida 100D with Siemens and Amperex Bugle Boys, at low volumes with a Creek 5350 SE and biwired-Proac Response 1s. The sound is great but I miss tubes in the amp..........and it plays 12 hours a day.
Room size 14 X 16 feet.
Any suggestions for that "tube" sound?
The equipment is housed in a lockable closet and cant be more than 12" deep to fit. It is locked as my partner likes to come in and turn the sound off!!:) (Philistine)

The Audion is sold. There a few new ASL SETs - 15-22 WPC all with a small enough footprint, eg ASL Fox. Almarro got an OK review in EnjoytheMusic, but not a rave. Any comments?
Well, I ended up with the Jadis, courtesy of Trelja, whom I think, somewhat guiltily, I coerced into selling it, although I doubt that he really wanted to! But he did, and my conversations with him revealed a truly passionate and knowlegeable Audiophile, who really loved his Jadis. I am running it with new EL34s, a modded Jolida JD-100 CDP (Amperex Bugle Boy and Siemens NOS tubes) with Proac S1 speakers. ICs are Wireworld Gold Eclipse 5, S/Cs Mas Signature bi-wires. The amp is superb; fast, dynamic, with a sweet mid-range and good, sound bass. Initially I heard an edgy, strained high-end, but as the tubes warmed up (now about 100 hours), this softened and the highs are now much sweeter and not edgy at all. Initially I thought that this could be a function of the S/Cs and that I would have to change them to cables that minimized glare; however, time on the tubes has softened the edginess and it is possible that the S/Cs will be OK. The other problem is the speakers - the Proacs are situated 6" from the wall, and, being rear-ported, they should be a few feet from the wall. But it may well be that the Jadis is "too good" for the accompanying equipment and I will soon bring it home to pair it with my Kharma 3.2s and EMM source, just for kicks to hear it at its best for a short while.
However, it certainly does the "job" in my office and has given me 100 hours of pleasure - for which I thank Joe! As always, I appreciate all your input on this forum - you have all been responsible for my best choices in audio, and Stereophile and Dealers' studios for all my worst ones..............:)
By the way, there is only one big negative to this amp - biasing. No way I can dissemble it in my office in its tight space, connected to speaker loads that are intricately threaded through holes, crevices and angles at the back of the closet. That's why I haven't tried KT 88s and KT 90s; nor will I for a long, long while. By the way, he (Trelja) even printed me his own manual on how to bias the amp. A true A'gon star! Thanks, Joe.
Brilliant suggestion! Thank you, Trelja. I have read all the reviews I can find and it sounds excatly what I am looking for. Thanks!! If you dont mind, could you measure yours, including depth of binding posts at the back. I have exactly 12" depth - width not an issue. If I have to, I can cut into the sheet rock at the back of the closet for i/cs and PCs. Are they still being made? I couldnt find the Orchestera Reference in their Blue book and there are none for sale on A'gon. I will pursue it. Much appreciated.

Thanks, Boa2. Wonderful suggestion. How would 12W work on a speaker of 86 db sensitivity? The dimensions would work out great. I could replace the Proacs with Totem Sig 1s, that I have at home - 86 db and 4 ohms.
Any experience with these amps without horns?

SETs seem to be the answer - the Almarro 318 may do the trick.
Thanks for your help.
I listen exclusively to classical, but sometimes turn it up when everone has left:) generally low volumes, but detail and nuance are critical. The SET Almarro 318 is 18 watts. Enough?
You have all been incredibly helpful - so much so that I made your task tougher byu taking out the shelfr and replacing it with a 15 inch one!!! So now I have 15" to play with. So, keep them coming!
I have a Jolida 502B at home - it's good but I want a more liquid, "magical" midrange and sweeter highs.
The Sophia EL 34 is exactly 15" deep. Opinions on this amp?
By the way, it's really hard getting dimensions off websites and I have to e-mail sellers to measure their units.
Boa2, the seller of the Audion Sterling e-mailed me that it was sold.
Trelja,
Who could do the conversion you suggest (and a very appealing one) from a Underwood modded 502B Jolida to KT88 triode operation?
By the way, I do run Svetlana KT 88s and Amperex Bugle Boys and NOS Siemens in the driver stages in the 502. I replaced the Stage 1 mod tubes (Electro-Harmonix 6550s and drivers) immediately as they did nothing for me.
Howard,
I received it and replied. You should have received it. Thanks for the heads up!
Trelja,
As the EL34s burn in the sound becomes more liquid, more mellow highs and better soundstaging. Its approaching 150 hours and sounds now like it did from your descriptions. It is one sweet, musical and special amp and I was able to listen long into night when everyone had left, at high volumes and the high end edginess has vanished.........just beautiful trebles. The mids are liquid and smooth, but not in any way cloying - just perfect.
Thanks again - I'm sure you will miss it. I'm sure as the JJ EL34s burn in, it will get even better. The sound from the same CD - Karl Bohm's Mozart Clarinet Concerto at home on my main rig played immediately after, was no more compelling! I see what the hype about the Jadis sound is all about; it really is a lush presentation, but very real and true.
Thanks, 711 smilin, but with the Jadis, I think I am now set(unless the biasing gets the better of me................)and very happy. Besides which, the Jadis can drive my Proacs with 86 db senistivity, which I don't think the Wavelengths can do. (Can they?)
Thank you all for your input.
711 Smilin,
Yes, I have the EMM combo at home. And the Jadis/Proacs are fine for the office - but thanks for the offer. The Jadis fits the size and it is sonically superb. So the set-up is done. Quest over..............:)I am now a contented audionut and I drive a Subaru WRX...............
711Smilin,
You are no man of half measures! How on earth did you go through 14 amps in one year? If you have the time, let us know if any were SET amps and why you ditched them?
