in principle, I find the idea of using 12 V tubes interesting and the implementation with the additional device good. There are certainly many great ways to find your personal sound with the tubes. For me personally, the variable supplay would be too uncertain. with a mismatch to cause damage to the tubes or amplifier. Do you have experience with the SRS551, F3a ; RS1003 tube?

The supply seems to be very stable with restarts. Since I'm only using one voltage right now I'm not worried about damaging any tubes.
I have not heard of those, please tell me more. I'm always interested in learning about new tubes |

Hi,
unfortunately I don't know much about this tube. It should be able to transmit frequencies up to the megaherz range. Rike Audio model Romy 20SE uses the tube. |

Does anyone know what voltage the input tube is run at? I love my cv1102 but it's max voltage is 250v and is designed to be run at 180 normally. I love the sound but I worry that I'm burning them up.
Edit: Nevermind. I see Dennis said in a much earlier post that the input tube is regulated at 250v. So yeah, guess it's not a great idea to run a tube there if its maximum is 250v. Last edited by Isaacc7; 07-29-2022 at 12:26 AM. |

Looks like some posts were lost in the weirdness with the site the other day. Oh well...
My current tube combo is the Tungsol round plate black glass 12sn7 with KenRad 6f6 output tubes. Very natural and easygoing kind of sound. Very well balanced. For those of you that have enough space on your amps for and adapter, or if your preamp is compatible, I can highly recommend the Raytheon 6j5gtw tubes. I've been using the 12j5gtw in my preamp. Super open and deep sound. I've switched over to using National Union 12j5gt. They seem a bit more closed in but a little richer sounding. Haven't heard a twin triode with the same kind of sound combo. |

Finally listening to the Sylvania 6k6gt. These look like later versions with the small top silvering. Combined with the 14af7 and Tungsol 5w4gt they are making sweet music.
Well, sweet as compared to the Ken Rad 6f6, Tungsol round plate 12sn7, and RCA 5y3gt. That combo was a bit brighter and a little more "hifi" sounding to me. Also, I think I'm giving up on RCA 6f6, they just sound flat and a bit tinny regardless of the driver tube I try. |

Another day at the toy shop....
A couple of fellows, Dave and Dan stopped by the shop to do some listening, and after we picked their jaws up off the floor, they decided to do some shopping as well. The 2A3 is now gone along with the first production 7C5 amp and the first pair of Inspire speakers to leave the showroom floor.
The master at work.... Untitled by analog addict, on Flickr The line up... Untitled by analog addict, on Flickr The new prototype phono preamp, my phono pre amp (no cathode follower) and a CJ5 preamp, (chosen for it's high/100Kohm input impedance) Untitled by analog addict, on Flickr The new 7C5 amp. The cost of the rectifier is probably 3-4 times that of all the rest of the tubes... Untitled by analog addict, on Flickr Untitled by analog addict, on Flickr Getting ready to head off to their new home.... Untitled by analog addict, on Flickr Both these gentlemen were essentially unaware of this thread, so I gave them the info. Hopefully they will join up and post their impressions. The Ziracote veneered pair of Inspire speakers will soon be for sale as well. Look for an ad in the Marketplace. We will be making more of these to order as well, in whatever veneer your heart might desire...

Hi Isaacc7, I can confirm the good sound of the Raytheon 6j5gtw. they are almost as good as my Fivre and cost significantly less. try the Phillips 6j5 mil. tube. looks like a 6sn7, but only 1Triod system is active inside. Very balanced sounded, and absolutely quiet. no rustling and humming. I have no experience with the 6f6, but I don't like the RCA 5y3gt. I find these a bit flatter and slightly metallic, try a phillips or slvania instead of this one |

the speakers in the d ́appolito design look great with the bright veneer.
what specifications will they have? a 45 or 46 pse amplifier or better still mono blocks in QMB-25 style could still be a temptation for me, but the 300b djh that drives my horns is already pure madness. it would probably just be different but not really better. eagerly waiting for the phono amp I ordered.... |

If I were going to test that belief, the 5y3 would be a good one to do it with. They aren't all that expensive compared to 5ar4 or 5u4. Maybe the next time I put in a tube order I'll try one. |
