Yamamoto sockets is a great choice even though it's expensive. However Tomas's suggestion to using Sowter transformers is pretty spot on. I don't even know the brand Sowter then. I only know Lundahl but Lundahl wouldn't do custom transformers unless the order is above 100. :)
Got to love the custom amp builds. Your amp will last you a lifetime and you already own gobs of tubes.
Just happy listening now :L3000:

Be careful with that GE tube, the GE inquisition will soon punish you. :)

That GE is a special GE. I'm using it now to drive the GEC KT66. I'd recommend Odyssey wholeheartedly, even if you have to sell your cats and dogs... or sell Bcowen.

It's a few years in the making. I dream about Berlin for quite a while. It's no longer just Berlin. It's Odyssey now. When I heard it for the first time yesterday, I knew then that it was all worth it.

Selling me would yield negative net proceeds. Perhaps parting me out would be more lucrative. :smile:

As long as we've veered slightly off topic, allow me the liberty to recommend the below album. It was recorded in DXD and if you even remotely enjoy piano and vocal jazz, the combination of Ms. Barber's phenomenal artistry and pristine, state of the art recording process should enable Odyssey and other high end gear to deliver their best:

Thanks for veering off. I've heard Patricia Barber songs but this is great. On Yggdrasil > Odyssey > LCD4, I was transfixed right from the opening note. Sounded good even on Youtube. Now let me see if I can find it on Tidal.

Yup I found it on Roon / Tidal. :)

Day 3 of Odyssey. I discovered that I can go UL mode with 6SL7 with no distortion. What a blast.

After 2 days with Odyssey, I'm getting a sense of what she can do, especially when compared to Chameleon. Chameleon has a grandiose scale. It's unbelievably grand and large in soundstage. Feels like an orchestra performing in an open prairie. The sense of spaciousness is uncanny. Odyssey also has a very wide soundstage but just not as wide as Chameleon. However Odyssey's ability to pick out notes with precision is startlingly enjoyable. With an overwhelmingly sweet and clear treble, a midrange that makes you want to sample every diva of any genres and the control and grip it has on bass and the lower register, my attention is totally fixed on Odyssey... and I have forgotten that Chameleon is sitting next to it. This is totally unfair. If I only had Chameleon here (alone), I would be transfixed listening to music but with Odyssey, I'm transformed !

Now to check myself in the mirror to see if I have become Optimus Prime.

The updated music room. Destiny cannot fit in the rack because the 300b tubes are too tall to fit in the lower shelves and the top shelves are occupied by higher ranking Autobots.

You obviously need another rack.

Glad to help, boss. :smile:

There's no room for another rack ! The shoebox of priceless tubes has to go. The CD player has to go. Schiit Eitr to be stack with Yggdrasil or I've to upgrade Yggy. Elekit probably has to go too. To make way for a Roon nuclues and a power conditioner / filter. Hopefully there's room for one more tube amp in 2023 but that has a lower priority than an Abyss or Susvara.

Radiotron 807 in action and I love the tone of these tubes ! Can't wait to hear it in Odyssey but I must wait for 5u4g rectifier. Bryant if you are looking in, get yourself a pair of these tubes. Some nice ones in eBay of various brands. I will pass you a pair of adapters.

807 in Chameleon is just beautiful sound and looks. Those are skinny 6FD7 drivers. With a Sittard GZ34.

I've set to 50 mA to be safe. Although it can be set to 60 mA as advised by Eric.

Anyone can be happy with either of these 2 tube amps. It will give a run with those established names and I've heard Wa33 and Auris Nirvana. If cost is no object, then definitely Odyssey because the execution is better, in terms of quietness and tone refinement but at the same time slam. Tube tone wise they are both so good.

Not forgetting Oblivion in the lower shelf. I had a quick listen amidst going from Odyssey to Chameleon. Oblivion still sound amazing and I love it. Bass is obviously less than Chameleon and Odyssey but Oblivion soundstage, clarity and details are outstanding. It's a great contrast with the other 2 amps.
