Great picture-reminds me I have stored away somewhere some squelchy feet from an old DiscMagic-I must try and find them. I am also enjoying using my new Ember with dual 6J5's. They seem to combine the warmth of my 'Bad Boy' with the detail and sound-stage of the 7193's. What is the main difference you are hearing with the 6j5's versus the 7193's, may have to give them a try. |

What is the main difference you are hearing with the 6j5's versus the 7193's, may have to give them a try. It's a bit soon to be sure but the initial impression I have is of a clearer sound with better instrument separation. However, I've only been listening for an hour or two with the Ember. What I can say is that it does sound very good. It would be great to know what others, like yourself, thought. |

Are the 6j5's a drop in replacement for the 7193? Seems to be. Interested to hear your thoughts after you have listened to them for awhile and switch back to the 7193's.

Yes, you need two though as each 6J5 is the equivalent of a single triode in the 6SN7's. I don't think 6J5's have generally been made for some decades as manufacturers developed the more convenient 6SN7's. The adapter is different because there are no wires to attach to any connectors on the top of the bottle. Solderdude explained the ins and outs of the pin set up a few days ago on this Forum. With this background information I wasn't expecting much difference in sound to the 6SN7's but when I tried them initially with the Horizon there was quite a difference from the 6SN7's. Brighter (in a good way-not edgy) and more forward- a very involving sound. In the Ember, with both my K612 and HD 650, the sound seems clearer than with my 7193's. The treble is a bit more prominent-and the sound-stage is wider and deeper, so instruments are better defined and their timbre more readily discerned. However, the sound is not quite as 'warm' as with the 7193's. Listening to some Baroque instrumental there is quite a difference and the 6J5's seem to bring the music into a three dimensional focus-a bit like when you put on those coloured plastic glasses watching 3-D movies.  The 6J5's IMO are excellent sounding and I think are different enough from the 7193's, 6SN7's and 9 pins to be worth exploring. They are not expensive and the adapters can be found from the usual sources on line. Obviously, it's early days-even my very new Ember is still 'warming up' and I should add I only listen to Classical and a bit of Jazz so what I think may not apply to other types of music, including other Classical genres-I still think my 7193's and 'Bad Boys' are excellent tubes. The tubes I am comparing here are the ubiquitous Ken Rad 7193's and Visseaux (French) and Pinnacle ('60's Russian) 6J5's. I hope this helps. Have a good weekend! |

Are you using a 6J5 to 6SN7 adapter on the Ember? Or 6J5 to 12a?7? |

6J5 to 6SN7. The 12AU7 adapter is just too short to allow the board to fit above the large capacitors, though you could use a socket saver to add extra height. You can see the adapter in the Horizon on my profile photo(Howie13)on Head-Fi.(#883 Project Ember Tube Rolling).
EDIT I don't think Ember will work with a 6J5 to 12AU7 adapter anyway. It may work with a 6J5 to 6DJ8 adapter-not 100% sure though.

Is there a technical reason why these dual-tube setups seem to supposedly beat single tubes (according to our partial impressions)? May single tubes suffer from cross-talk between channels or interference? I am very curious to know... howie: thanks for the info! |

You're almost there mate  I'm going to assume you're doing this on a standard desktop browser. It's sadly not quite so straightforward when using a mobile app (at least on Android anyway). OK, I'm using Firefox. 1. Navigate within Photobucket to the image you want to share & you'll see 4 options to the right of the image. You want to left-click once in the box marked Direct..  2. Navigate to the thread on DIYAH in which you want to insert the image and hit the REPLY button to open up the full text editor interface..  3. Once the editor is open you'll notice a group of 9 buttons at the top rightish of the page. You want to hit the 3rd from the left. This looks like a photo of a lanscape scene and is the INSERT IMAGE button..  4. This will open the INSERT IMAGE pop-up dialogue where you will paste (right-click, paste) the link you copied in step 1..  5. Click INSERT IMAGE and you're done. Rinse & repeat. There's an even easier way once you have several images within Photobucket which cuts out the part where you navigate to the individual image. In Gallery Mode you just hover over the top-left corner of any image & it will give you the option to show Share Links. Just choose DIRECT as you did in Step 1 above. Notice I haven't posted your images myself. That's your task should you choose to accept it (rofl)BINGO! I edited the picture into the original post. This is an excellent tutorial for others also. Many thanks! |

I've been wondering the same thing & this is the only rationale I can come up with. You would think with the adapter and the extra connections that the sound would suffer and not, if anything, be better. There must be an explanation somewhere. |

I had a look on ebay and the Visseaux is about 4 times the price compared to the Pinnacle 6j5. How do they compare sound wise? Thanks. Most of the comparisons are with the Visseaux. I had a short listen with the Pinnacles. They are not dissimilar in sound stage and signature-maybe slightly more emphasised upper-mids and less lower mids, making for a cooler sound overall-BUT these are, I believe, genuine unused tubes and probably will change in character in the next few days/weeks, so I would take these comparisons with a 'pinch of salt'. Also, my Ember is very new. I have also listened to some ?1940''s? Sylvanias, which sound similar, though maybe again just a touch less warm than the Visseaux. Could just be a burning in thing-this is uncharted territory with these 6J5's. I do think the Visseaux look very impressive, and they glow very strong-even the wife likes the look of them -so that, alone, makes them worth the price!! |
