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

[CohibaJoe]

I've read in this forum that the 8900 is best paired with the TU-8550, but I don't see it in the DIY Audio Store. Is the TU-8550 expected to be in stock any time soon?

I would go thru the TU-8550 upgrades threads as the pairing with the 8900 would be nice. I would call the sound signature as "Modern" and not like a Sunvalley Amp "Traditional Tube sound."

Has anybody tried the Jupiter silver foil vitamin-q yet I'm pretty interested in comparing them with the V-cutf I have at the moment.

@ Victor do you stock these? If so would you pm your price for a pair for my TU-8900.

Thanks Jamie

hi, I found some reviews of Jupiter silver foil there:

I used these comet silver caps in TU-8600. AS i said the Comet is afforable but AN silver is AN silver.

 

[psykokura]

i still have few in stock. Diy store will have stock in mid July

Does the 8550 pair well with an 8800 as well? How do I go about ordering from you directly?

 

[vkung]

yes it is ok with TU-8600S/TU-8800/TU-8900
please send your email to info@vkmusic.ca

Matching headphone impedance/volume levels.

You can change the headphone impedance/volume levels by
simply removing the front panel and change the position of a
short pin.

Hi Victor,

On this picture, what is the impedance? Medium Low impedance? Having 8ohms headphones, should I move the short pin to the right?

Thanks

Thanks

 

[vkung]

Yes according to the manual you should move to far right
You should test Low Med too to see which setting is your taste

 

[Gruesome]

So, this jumper position is medium level for low impedance headphones, it seems. Are the jumpers like on the TU-8200R, where the jumpers select the fraction of the output, and the hi/low impedance selects the output transformer tap, except here impedance and level are combined into the jumpers?

 

[vkung]

they are different..

 

[Gruesome]

From what I read, in the 8900 the headphone output is driven by the same tubes as the speaker output (as is the case in the 8200), so some things (like providing a load for the output transformer) have to be similar.

 

[vkung]

more options than TU-8200

 

[Gruesome]

Is there an 8900 schematic posted anywhere?

 

[vkung]

no. copy right...

 

[Gruesome]

But the 8200 ( not R, the original) is online. As long as it's not for commercial purposes, it should be fine, no?

 

[vkung]

ELEKIT does not allow to post any copy tight material on the WWW.

Hi , hope someone can give me some advice. I have recently built the TU-8550 pre amp to go with my TU-8900.
where should I set the volume control on the TU-8900 ?

 

[vkung]

i will set the TU-8900 at

12 o'clock position​

Congratulations Victor on such a superb and well deserved review of the tu-8900 by Herb it was a pleasure to read.

Edit I'm looking forward to leisurely re read again tonight but this time accompanied by a night cap and some tunes from the amp.

 

[vkung]

It is my passion
