Very interesting and strange. The WA33 that cost up to $18000 like the Mono but dose not used the 300B? Am I not reading the specs right? If correct,

The WA33 is a useless amp. No 300B say bye bye.
People should buy the Mono https://wooaudio.com/amplifiers/wa234mono if they are Woo fans or the WA5

Since you're also listing tubes: KR Audio KR300B Riccardo Kron Limited Edition (matched pair)

WA33 is probably due for a refresh. First release was 2018, so it's 5 years old. A solid amp, but yes, not 300B.

Yes, I want the best 300B tubes out there.
I am only familiar with Sophia Electric Princess 300B. Excellent company and tubes.

I have a KR 5U4G Riccardo Kron Anniversary Edition in my (lowly) Woo Audio WA6-SE Gen 2, and it's the best rectifier I've heard yet. Including my Takatsuki - which reminds me: Takatsuki 300B

While I'm at it: Emission Labs 300B, Emission Labs 300B 2.5 (The EML 300B-25 is a direct replacement for the 2A3 tube), Emission Labs 300B Mesh Long Annode, Emission Labs 300B-XLS, and Emission Labs 320B-XLS (The intention of 320B-XLS vs 300B-XLS. With tubes, when increasing the heater power, the tube gets more suited for harder conditions. For this reason we recommend the 320B in situations where 300B-XLS would be used near the end of it's possibilities. Such as biased close to maximum, and for Push-Pull amplifiers. Though Push Pull can be made with any 300B, it is known to be harder on the tubes than a Single Ended design).

The KR 5U4G RK is NOT a 300B - they make a 300B variant, see previous post.

Also Elekit 8900, and this thing takes both 300B or interchangeably to 2A3 as well

Did you build the kit? How hard was it? I've been toying with the idea of building one for giggles.

Looks nice but not a headphone 300B Amp?

Ok, technically, no. With an adapter though...

Yes sir! It is fun if you have built amps before, upgrade options are going to raise the price a bit.

Just here as a very, very happy Manley Audio Labs Neo-Classic 300B pre owner. They are simply phenomenal, especially with speakers.

Will be doing a full tube replacement in the coming months as the current tubes are 10 years old. Likely going for the new WE 300Bs, 5691 RCA Red Base for the 6sL7 and the Takatsuki TA- 274B for rectifier tubes if the budget allows. Not sure which 0D3 to go for. Maybe Mullard or JAN?
