The Tung Sol 76 have the same metal spreaders but have round plates instead of the flat ladder plates.

Bought this tube the other day, very nice sound, but more for the reason that I already own a pair for Envy…and it just seemed logical 😜 to buy a single for the Crack! I only posting now with a few pics as I like the box. Sad I know 😀.

Edit: Oops! Sorry wrong thread!

Cut it in two and you’ll be in the right thread.

We like pics of tubes with boxes. Well I certainly do 🙂

Are pentodes we will turn into triodes allowed here? Since the 6c5 is just a trioded 6j7 I figure it’s fair game right? Check out this Fivre 12j7, what a looker!

Picked up some Brimar 8d2 tubes. Those are a 6j7 with the old British 7 pin base. Thought another tube I was going to get would use the same pin out so bought these. Turns out I was wrong so I’m not sure I’m willing to pay for the adapter just for these tubes. Plus they are so big I don’t think I’d be able to use the 2 8d2 to 6sn7 adapter in my amp, just my preamp. Still, they are a good looking tube.

This last tube I bought because of its reputation. The c3g tube has a sterling reputation as a driver in both pentode and triode. I have no idea how it will do as a triode and paired up to replace a 6sn7 in my amp but I’ll give it a try. I use external supplies for my amp so I was able to buy the 20v c3m instead of the more expensive 6v version.

I’ll have to order some adapters to actually use these, dunno when that’ll happen but I will report back!

ここで三極管に変換する五極管は許可されますか? 6c5 は三極化された 6j7 にすぎないので、公平なゲームだと思いますか? この Fivre 12j7 をご覧ください。

Brimar 8d2 チューブをいくつか手に入れました。それらは、古い英国の 7 ピン ベースの 6j7 です。私が入手しようとしていた別のチューブが同じピンアウトを使用すると思ったので、これらを購入しました。私が間違っていたことが判明したので、これらのチューブのためだけにアダプターの代金を支払うつもりがあるかどうかはわかりません. さらに、それらは非常に大きいので、2 8d2 から 6sn7 へのアダプターをアンプで使用することはできないと思います。プリアンプだけです。それでも、見栄えの良いチューブです。

その評判のために私が買ったこの最後のチューブ。c3g チューブは、5 極管と 3 極管の両方のドライバーとして高い評価を得ています。三極管としてどのように機能するかはわかりませんが、ペアにしてアンプの6sn7を交換しますが、試してみます. 私はアンプに外部電源を使用しているので、より高価な 6v バージョンの代わりに 20v c3m を購入することができました。

これらを実際に使用するには、いくつかのアダプターを注文する必要があります。それがいつになるかはわかりませんが、また報告します!
このアダプターを使えばOKです。

Hi @Xcalibur255 ,

What are your top 6J5 tubes? Which one is the most detailed? Best bass? I like to pair my Raytheon 6J5WGT with the Elrog ER for classical or acoustic guitar. Amazing strings.

The 8D2 is a 13V tube. Luckily, my amp is not wired that way...another rabbit hole successfully avoided :dt880smile:

Yeah, what you said. Next thing we'll be hearing about is 1960's CRT's wired as single triodes. 🤣 🤣

I use external supplies for the heaters in my amp so it’s rabbit holes all the way down for me:)

Bottlehead Crack w/ Speedball modded to use 6J5 (etc) up front. Running some just received GEC L63 (Langrex on eBay) with a Chatham 5998 in back. This chain:

Volumio ==> mTT2 ==> BHC ==> Atrium

really reinforces the every track sounds great aspect of Atrium. Emotion pouring out of the ear cups!

Gratitude for all the great advice provided here.

I clipped @Xcalibur255's 'best of' 6J5G

He did detailed reviews of all these contenders and will more than likely answer you question regarding bass and detail
