Re: GAT2 tube choices and recommendations?
I’ve tried many NOS ECC88s and 7308s and settled on Mullard ECC188s, and also on the Art 300s.

Re: GAT2 tube choices and recommendations?
Joe
Have you still got those NOS 6H23p tubes we bought from the guy on Ebay? If so I would try those first. They sound pretty good and will last longer in the GAT like they did in the AI preamps. If you want to try Mullard I would call Andy at VTS and prepare for "sticker shock." An alternative is the Matsushita tubes made in the factory Mullard personnel set up. They are pretty close in signature and half the price.Main - JVC QL-Y7/Denon DL-301 Mk II, Gold Note PH-10, Jays CDT3 Mk3 , Auralic Aries G2.2, Holo May KTE, Supratek Cabernet, Kinki Studio EX-B7 monoblocks, Verity Audio Otello, (2) Rythmik F12SE, Audio Envy IC, SC & PC's, Triode Wire Lab PC's, Inakustik USB and I2S, (2) Puritan Audio Labs PSM-156 with Groundmaster City, Timbernation rack

Re: GAT2 tube choices and recommendations?
The 6h23p is a direct six volt replacement for the 6DJ8 family just a more rugged Russian military tube and was all they could find to work for any length of time in the Modulus 3 preamp. They are definately better than the new stock tubes CJ is providing.

Re: GAT2 tube choices and recommendations?
I had the 6H23 in my original GAT, they sounded great and lasted a very long time.

Re: GAT2 tube choices and recommendations?
Thanks Joe. As you know, I'm currently very happy with the original GAT and contemplating a move up to the GAT2. Net cost after sale of my current unit will be about $5-7K. My Gat is number 14, an early unit. Unlike others, I've had no issues with tube failures. Some NOS tubes became noisy but I attribute that to some weak or old tubes. All newer tubes from C-J and the Russian types from Canada are fine.
I asked Jack about the tubes he recommends for the GAT2 as I don't want to "buy" a new tube problem in the upgrade process. If the original is working perfectly, maybe I should leave well enough alone.
Jack, I'm also running the new ART Stereo 150 with the original factory small signal tubes and they are fine. Do you suggest a change there also?
Thanks,
Bob

Re: GAT2 tube choices and recommendations?
If you prefer a little more neutral, cleaner and clearer sound, get the upgrade. Otherwise if you love what you are hearing and prefer a slightly sweeter more romantic sound, leave the GAT alone. I know of owners going back to older or original CJ pieces after selling or upgrading to GAT2 or new ART amps. I also know many who absolutely love the GAT2 and ART150/300 amps. It’s all personal taste.
For the record, I’ve never had any tube issues with either my GAT or current GAT2.Fleetwood Deville by Oswald Mills Audio, Vienna Acoustics Haydn Jubilee, Wharfedale Linton w/ stands, Klipsch RB-75, Klipsch RP-160M.

Re: GAT2 tube choices and recommendations?

They are a slightly warmer tube than current stock and more durable so longer lasting. If you are happy with the stock tubes then I would stay put but if you want to try something different then get a pair for the preamp and see what you hear. Ebay is probably a crap shoot for them nowadays so your best bet is probably Parts Connexion.Main - JVC QL-Y7/Denon DL-301 Mk II, Gold Note PH-10, Jays CDT3 Mk3 , Auralic Aries G2.2, Holo May KTE, Supratek Cabernet, Kinki Studio EX-B7 monoblocks, Verity Audio Otello, (2) Rythmik F12SE, Audio Envy IC, SC & PC's, Triode Wire Lab PC's, Inakustik USB and I2S, (2) Puritan Audio Labs PSM-156 with Groundmaster City, Timbernation rack

Re: GAT2 tube choices and recommendations?
Thank you Gentlemen for your replies.
Joe... the key word from your message is "little". Spending $7K for a small improvement makes little sense to this 76 year old guy. But, it's still tempting.

Re: GAT2 tube choices and recommendations?
Bob,
I trade you my GAT2 for your GAT plus 7K
Seriously though, by saying little I don’t want to scare anyone away. GAT2 is improved and it’s not trivial but everyone’s taste is different.Fleetwood Deville by Oswald Mills Audio, Vienna Acoustics Haydn Jubilee, Wharfedale Linton w/ stands, Klipsch RB-75, Klipsch RP-160M.

Re: GAT2 tube choices and recommendations?
Well said Joe! I've stayed with GAT2 and the ART300s and I see no way of any major improvements without spending piles of $$$.
For me, the GAT2 was an improvement, however I have zero doubt that others could prefer the original GAT paired with the prior generation ART amps.Magnepan 20.7 - CJ ART 300s - CJ GATV2 - Meitner MA-1 V2 -Dedicated JRMC + Synology NAS

I upgraded the power supply on my Gigafoil v4 to a Weiss PSU 102. It’s very nice step up. But with the new model, you’re looking at $2000 before even investing in a SOTA linear power supply.
