ELEKIT TU-8900 2A3/300B (Stereophile Review Available NOW - July 2023 Edition)

Hi Victor,

My July issue of Stereophile arrived this afternoon so I had the pleasure of reading Herb’s review of the Elekit TU-8900. He spent a lot of time with it using multiple speaker models and feedback & no feedback. He referenced you multiple times. Great article/review and you must be very happy as orders will surely come your way!

Enjoy working at THE SHOW👍👍

Congrats,

Vir

Congratulations, Victor! "Most compelling sound system [..] since I had started writing for Stereophile". (Which is more than a few months, I believe...)
I'm glad I got my TU-8200R kit before the Stereophile hordes are coming knocking down your door, demanding you take their money and give them their TU-8900! If you need to borrow a wheelbarrow for the Costa Mesa show, let me know... ;-)

Are you allowed to post the full review text on your web site, maybe?

I just read the review and it was super interesting. Sounds like Herb used it a lot as a 300B amp and I was trying to discern whether he liked it more than the 2A3, sounded like he did the bulk of the listening with 300B?
What do you all think?
I prefer the sound of the 2A3 by a good margin on transducers that aren't held back by the 3.5W. With transducers that love a little power, the strengths of the 2A3 doesn't come through as strongly and the the 300B starts to pull ahead with a larger and dynamic presentation.

Do you think the Klipsch Forte I would run well with the 2A3?
 
Do you mean illegal?
Some of Herb Reichert's articles are also on his website/blog, or on the Stereophile website. For example, his musings about the TU-8600R are here: https://www.stereophile.com/content/gramophone-dreams-27-elekit-tu-8600r-amplifier-kit

There are some odd statements in there though. Like, when he states
"The chief difference between an EL34 pentode tube, with its five active elements, and a three-element 300B triode is that EL34s have electron-emitting cathodes that are activated by separate heaters that warm them up to emission temperature. In contrast, 300Bs are directly heated tubes (DHTs) in which the tube's filament/heater and emitter/cathode are fused into a single element, the metallurgy of which is an important factor in determining the DHT's overall sound character. Typically, DHTs amplify signals with a liquid but also strict and überclean forthrightness. Contrary to popular myth, the WE 300B doesn't sound "sweet" or "romantic." I coined the descriptor "water-clear" to describe what I recognized as the WE 300B's dominant virtue."
Isn't that, pardon my überdirect French, simply wrong? I mean, it's hard to argue against the simple fact that the chief difference between a triode and a pentode are two electrodes, namely the screen and the suppressor. The screen reduces the grid-anode capacitance and thus coupling, the suppressor shields the screen from low energy electrons liberated from the anode. Isn't that way more important than direct vs indirect heating for the amplification characteristics and the sound? I'm a bit puzzled.

Anyways, maybe his TU-8900 review will also show up there.
