Just lost a bid on 13 6sn7gt valves... next time, so I can give my opinions too about 6sn7 type compared to noval ones Why would you want so many valves? Those were a bunch of amperex, mullard, rca, ge and ken rad; I was interested in comparing all

Because you can never have too many valves! Hello Musicman, what are you thinking after many more hours with the 7193 tubes......? here i read another review of this tubes... what do you think : « In my experience, the 7193 is sonically superior to any 6sn7 regardless of manufacture... nos or otherwise. Comparatively speaking: the 7193's sonic signature is a combination of the best of the 6sn7 family. Combine the bass power and depth of the Kenrad black, the 3 dimentional midrange of the old tungsol round plate,the bloom of the Rca grey glass with the treble extention of the best nos sylvania's. Although a little more difficult to find these days, they generally sell for a fraction of the cost of the nos 6sn7's.»

Richard51, I am still evaluating the 7193's. I do like them very much, but until the matched set of kenrads get here, it is hard to say if I like them better than a singel 6sn7. They are up there to be sure, but the single kenrad vt231 has more bass, so it should be interesting to see if the better 7193's sound better than the mixed set I have now.

You guys wanted an update on things... here goes - Linear PCB looks finished and turned out great! Frans and I went back and hit it over the weekend. Maybe 1 minor tweak when I get back in this evening and boards will be ordered. Felt like it would never be completed as we always had something else come up. Almost here!! Once testing is verified, Production boards will be ordered and the chassis will be built. Part of the long delay is I simply did not know what to do with the chassis as I did not have a manufacturer lined up. That all changed with my new machine shop and their capabilities. - Once I order PCB's for the linear, filters will be worked on / starting this week So far it has been a BUSY year for us. Even though it seems like we were quiet... here is what has been accomplished in 2015. Basic change log on my site under news-blog:- Ember updated to version 2 - Polaris bumped to rev 1.2 - Starlight bumped to rev 1.1 (excited about this as it puts the amp WAY above its price point with added features - Starlight does not get enough credit in its price bracket!!!) - Sunrise at rev 3.1 / Horizon almost there - Solstice was launched - All manuals were updated for the new revs - 6SN7 adapter was launched with great success! - All acrylic chassis updated visually and have 34mm cutouts for 6sn7 and variants. Sunrise / Horizon are the only ones remaining and will be released in the next two weeks - CNC'ed chassis were released for all amplifiers Not related to G1217 amplifiers:- 6SN7 adapter was launched with great success! - 6gh8a to 7199 adapter for dynaco and other amplifiers being launched in about a week - PCBs en-route - 6sn7 to 5670 / 396A adapter being launched in about a week - PCBs en-route - Replacement PCB for B&K747 tube tester / will be available as the PCB only or pre-assembled Upcoming:- Linear will be available FINALLY! - In-line filter setup YAAH - Replacement PCB for Sencore MU140 and 150 tube testers So in short... while quiet, things have been BUSY

You're right about the Starlight Jeremy. Not ao much talk about this one Nd yet, it's a lovely amp.
Trouble is, I like them all!!! I don't know why, but I did miss the Horizon when it went. I became very fond of that. But then Gain, I wS also very fond of the Sunrise.

Excellent news Jeremy!
I'm still not clear on the benefits of a linear power supply but if you're building them I guess there's a need. Can anyone link me to talk of linear power supplies?
Also Jeremy, will the new acrylic top-plates be made available to buy separately in the Parts section of the G1217 site?
Gordon.

Jeremy, what time do you have left over for your "life"? Much appreciated though. Onwards big guy!

This is my life now, although just part time... or I should say... all remaining time in a day For most, the linear is not needed. What it will offer is a drastic reduction in noise when the amp is used in a noisy environment. I have also found that it will quiet down tubes that are prone to noise and hum like 12ax7's - or the random noisy tube that seems to pick up everything. I doubt a ton of the supplies will sell but for those that need it or want to take things to the next level - it will be a blessing. It can also be considered a last level upgrade over doing a custom battery setup. But again - the reality is, if you do not have noise / hum / certain tube issues because of the environment your amp is in or equipment it is in close proximity to (vast majority do not have these issues) then the supply is not needed. The linear is designed to run 24 or 48V (power all Frans/G1217 gear) which can be changed internally via a switch. It is 115/230v with minor tweaks so it can be used in the US or overseas. Another feature is that it can be customized to run other voltages. However, this will generate a lot more heat so... customization should be discussed prior to doing so. The new acrylic chassis are available anytime now as are the CNC'ed chassis. Serial numbers will not match as our laser guy hates doing 1-offs. Not a big deal as we do not track the amplifiers via serial for warranty, we track them via the owners first / last name, email or shipping address.

Thanks for answering Jeremy. I'm lucky then because I hear no electrical noise at all here so that's money saved.
Good to know about the acrylic top-plates too. Don't get me wrong though, I do actually prefer the aluminium one I have but it might be nice to ring the changes now & again. Serial numbers are, as you say, irrelevant.
I'll hang off for now because I definitely want one of the HD 650 filters so I'll order both at the same time.
This amp's sounding just sublime now too. I replaced the Linn interconnect going from the DAC to the amp with a QED Silver Anniversary & the combination of it's detailed airiness and the Sylvania 6SN7GTA's warmth is absolutely beautiful.
Gordon.

i have a question.... I decided to connect my hifiman 400 to the headphone out of my Monsoon mm 2000 powered speakers... The Ember is only pre amp in the chain.... The sound is better more bass, better higher frequencies, better soundstage than on the Ember headphone out.... But without the Ember preamplification (tube6sn7) the sound is not comparable.... My question: is the sound of the tube more directly felt with the pre/out function than with the headphone /out on the Ember ?
P.S. The ember is very important for this pre amp function with my speakers... the effect of the Ember on my speakers is remarkable...now i watch the same effect with my headphone directly connected to the amp of the monsoon....

is the Ember the best tube Pre amplifier for the price? i think so because the effect if you change tube is very sensible...
