In my system, with Starlight, Horizon3 and Ember, Bad Boy has more warmth and bass presence. It's sweeter on top too. The Shuguang is more neutral and has a cleaner sound. Sound stage is as wide as Bad Boy and a bit deeper, imaging higher frequency instruments, like flutes and violins rather better. The bass is more articulate but not as deep as with Bad Boy. Bad Boy is more engaging with vocals and bass instruments. However, I've only used the Shuguang for a few hours and it's said to require many more hours than that to reach its best, particularly for the bass to open up. Bad Boy has been used for about 100 hours, so is probably at his best now. They are both excellent tubes, synergising very well with all three G1217 amps. The other thing worth mentioning is the Shuguang is completely silent. Here's the link to the one I bought. I see the markings of these tubes can be different. I just wonder if the sound is too. www.ebay.co.uk/itm/261595519004?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT |

Hi Howie, I always liked the look of that tube, but the price was up there a bit. I have spent that much (a little more actually) on a KenRad Vt231. I wonder if there are different tubes being made, according to their site....The tube with the same current data. In March, 2012, newest design and printing has been adopted to prevent fake tubes in the market.Harder box is now taking the place of black box for the safety of tubes. Especially the label of Shuguang proucts is now printed on the box. Makes me wonder how many conterfeit's are out there. If I get one I will use this link, also. Let us know as the tube gets some mileage on it.

Let us know as the tube gets some mileage on it. Sure thing. Fakes are always a worry. This tube has a sticky label attached with a unique number written on it, supposedly to show it's genuine. Who knows, but anyway it sounds very good and clearly up there with the best. I would say it sounds closest to my Tung-Sol RP at present. Compared to the Ken Rad it doesn't have as much bass (no surprise there) but has rather fuller and better projected mids and highs.  |

Thanks Howie may have to give it a try. Still very comfortable with my 7193's

Thanks Howie may have to give it a try. Still very comfortable with my 7193's 7193's have a more holographic sound stage and the Shuguang is more neutral and detailed. I like the Shuguang for smaller scale instrumental and the 7193's for larger scale music. |

The 7193 sounds great. But I keep using much more often to the Sylvania 6SN7 "Bad Boys" or even my Reflektor 6N23P "single wire". I cannot spot exactly the reason why though, it is hard to fault the 7193 except for ultimate bass extension (at least with the tubes that I got: Ken-Rad). (Don't lynch me now for saying this! :-) )

(Don't lynch me now for saying this! :-) ) No lynching, in fact I think I know what you mean. When I compare the 7193's with 'Bad Boy' and some 6J5's I find the 7193's lower mids can sometimes sound a bit muddled in complex mixes and the treble a bit bright-at least with the Ken Rads. With the RCA 7193's the treble is a bit attenuated and more comfortable to listen to at loud volumes, though sometimes it's just a bit too warm. However, with a clear, spacious recording of a large orchestra I think the Ken Rad 7193's can be very impressive indeed. I still prefer 'Bad Boy' tubes for vocals though-beautifully seductive and engaging. |

Well spotted howie, I think that comprises my experiences too with the 7193. A bit unrelated, a few weeks back I (shamefully/impulsively) sourced a number of real(*) Sylvanias 6SN7GT "Bad Boys" (black base, green letter, black plates, 3 hole mica, from 50s, 51s and 52s, all sounding identically good) relatively well priced and tested by the seller. I was intending to just save them and have them as spares, but I guess I will never use more than 2 or 3 at most :-) If any regular member of this forum would like to buy one and cannot get them at a reasonable price on ebay just let me know, my price will be exactly the same that I paid for them: around 42 EUR (400 SEK) + shipping. I should probably write this in the corresponding sales section :-P * I also have tried a similar Syl tube from 1951 that looks like them, but it has gray plates, two holes and not as nearly good bass. Some more info about these tubes: db.audioasylum.com/mhtml/m.html?forum=tubes&n=256992&highlight=decola&search_url=%2Fcgi%2Fsearch.mpl%3Fauthor%3Ddecola%26user_id%3D61763%26forum%3DALL%26sortRank%3DNone%26sort%3Ddate%26sortOrder%3DDESC&r= |

I already have three myself otherwise I would have been very tempted to buy one of those from you. |

Yeah, my first bad boy came in a batch of three Syl tubes that I bough for $20 (the seller had no idea), but it was in pretty bad condition and one of the channels started to fail now and then. But it gave me a good taste of how good they can sound. When I decided to get a good one, it was very hard to get just one tube reasonably price on ebay. Most of them had 2 holes in the mica and they were from 1951, so you never know (if at least they had 3 holes...). Until I found this batch priced reasonably well per tube (still more tubes than I needed).
In the worst case, I can wait 10 years to sell those tubes, who knows what their prices will be by then :-D

Frans, do you know if the Ember + power supply fit in the same outdoors case that came with your Polaris? (B&W Type 1000). It looks like it, but the PS in the Ember is significantly bigger.

The outdoor case is a shipping option Jeremy provides.
You may have to ask Jeremy which adapter he ships it with.
I assume it will fit in the outdoor case though.

The B&W 1000 cases do not fit Ember and powersupply well at all - in fact I do not recommend it. Their older type 10 case (which they discontinued) were great and fit power supply and amplifier perfectly. Wish they did not make the change!
If you can find a type 10 case with pluck foam, that is the one you want.

Thanks Jeremy.
I did not even know that the Ember and Polaris could be ordered with those cases :-( (well not the Ember any longer)
The type 10 can be bought in Europe on (e.g.) Amazon.de
The dimensions of type 10 look rather similar to the type 1000 though:
Type 10, Inside dimension: 250 x 180 x 80 mm.
Type 1000, Inside dimension: 250 x 175 x 95 mm

Unfortunately, with the way the pluck foam is and in practice, the are quite different which is why we deleted them from our site. If you can order a type 10, you are set!
