Good lucki'm looking for a 300b recommendation. my preferred genres are thrash metal, power metal and other sorts.
please only recommend tubes with 2+ years warranty.

Allnic 300B:
Presentation is nice and ubiquitous with its packaging.
First thoughts: definitely better than ACME, second thought more linear than WE300B.
Subsequent impressions they maintain 300B sound with more exercise as they're not as bloated or blunted although, to be clear, they aren't as proficient as Elrogs and nothing probably ever will be unless using the same materials.
A lack of sweetness is present comparatively something that I'll boil down later.
I'll let 'em burn to 100 hours, without quirks, and dig into the minutiae more.
I am sure manufacturing is slow and painstaking which calls the price, but we need more approachable 300B options and those better delineated compared to their performance IMO. It won't happen but a gripes a gripe.

Good report!
How does the quality of construction look to your eye? As far as I know you and @ColSaulTigh have the largest collections and the most experience with 300B tubes here on Head-Fi. Just wondering if you'd share a bit more on even the glass envelope quality as well as the ever important internals quality.
For example my Elrog 300b Mo have a very substantial and hefty glass envelope. One can really see it and feel it in hand, the quality.
Thanks so much.

The quality looks good although it feels the industry follows a WE formula but between the glass and filaments, care is present.Good report!

They aren't overbuilt like Elrogs as far as the construction goes.

We take turns blowing small fortunes on light bulbs. Currently I've been on a vinyl kick, so I'm leaving the heavy lifting to others at the moment. I'll probably do some more acquisitions in 2024 (I'm lookin' at you, TM's...)Good report!

Have been running this 300B SET amp, Raphaelite ES30, for about 10 months now. IMO, built quality is great, up there with other Chinese amp manufacturers like Cayin and Line Magnetic. BTW, Raphaelite started out as a transformer manufacturer and it is very well known for its quality in China.
A while back on this thread, I said I was working on a 300B amp for Zach Mehrbach. Well, we decided to go 2A3 instead since he has a few 300B amps already, really happy with the outcome. Thought I'd show it here since ya'll are DHT heads. Build details:
- Custom mains and filament transformers from Monolith Magnetics
- Separate B+ and bias supply regulators for each channel to minimize crosstalk
- Rod Coleman filament regulators
- 5687 / 7044 / E182CC input stage, LED biased
- Monolith Magnetics nanocrystalline core interstage transformers
- Fixed bias 2A3 output stage
- Monolith Magnetics nanocrystalline core output transformers with 120ohm, 32ohm, and 8ohm taps
- Besides the power supply, no capacitors in the signal path
More pics, details and measurements here: https://www.head-fi.org/threads/l0rdgwyns-diy-audio.921105/post-17796349

I was ready to buy those allnics but I just found out they scrapped production due to the recession in Korea, unfortunately. So FYI for anybody that was interested.Allnic 300B:

I doubt it, but if you ever want to let those go hit me up!

Lots of politics with this one.It was direct from allnic, fwiw
Allnic stopped 300B production. Full stop.
Zero Mountain will continue.
Unfortunate.

The Allnic 300Bs were going to be a holiday gift for me from my family.
Well, maybe I'll try the Stradi...

Audio Note 4300E still gets high marks from me.Too bad!

Thank you. The truth is the I'm more curious than anything.Audio Note 4300E still gets high marks from me.
I'm very happy with the Elrog 300b Mo. As a matter of fact I think it's taken nearly 300 hours for them to really strut. The were very good early on. Now they've filled in and have a tremendous texture and depth. Really a very special tube.
