I’m guessing the testing faze is more absolute than the classic and premium treasures, purely speculating, but the website is quite descriptive in this area.



 



And there more expensive to boot, so there got to be better, its part of the audiophile bible...


 



Has anyone compared these reissue tubes with something like xf2 Mullards (or rebranded Mullards)? Currently using a quad of reissue Russian Mullards, and would like to try something else to see if there is room for improvement (on a T2).

Yes, I have.  I'm running a Quad of XF4 after my Shuguang Treasture went dead on me.  The original Mullards have better resolution and better dynamics.  The warmth is about the same but overall it is just more refined.  The original Mullards compliments the SR009 & BHSE & DIY T2 very well.  I'm sure the XF2 will even be better but the improvements over the XF4 should be very very slight.  Owners of XF2 & XF4 seem to have tough time telling them apart sonically though.  Visually speaking, I prefer the black Shuguang Treasure on the BHSE though...it just look very very cool.

 

Note that I've never tried the Shuguang Treasure on my DIY T2.

I'll gladly bring my quad EL34PH to your place and see how they sound in the T2 (have the Shuguang treasures too) :biggrin:

Purk, remember that the XF4s you have are not the typical ones that were produced after XF2s.  The XF4s you have were produced before XF2s...

Just received another batch of polished/anodized BHSE panels. They will need inspection. Just wanted to post this here to show the complete idiocy i have to deal with on a daily basis. Absolute crap.

 

 

 

 

i had hand delivered the panels in a box that was built like a fortress with 1/4" thick edge protectors on all sides. I got that one back too - it was used to package the metal feet. The panels went in the foot box.

weird, I thought the xf4 were the version without the welds (where they were stamped through and bent) which I had assumed came about as a change in manufacturing, which I also assumed took place after they stopped making the xf2. Learning all the time.

Yes, I know that.  My comparison was made using my personal set of XF4 vs. the Shuguang Treasure before I recieved the set from you.

rock beats paper in this case. if there is no damage it will only be because of the round radius on the left/right edges of the panels + packaging them back to back which creates a semi-circle. if they were square corners they'd all be crushed. but they can only get lucky so many times. i have lost many shipments this way.

I could definitely be wrong, the guy I bought 6 quads from said these are holland made double d getter late 50's 1st version XF4 made prior to the series restart with XF2.

Trying to upload a pic but not working so far...

XF4s

post #4347 of 6034

It is possible. Check this website http://www.tube-classics.de/TC/Tubes/Valvo%20EL34/EL34.htm

 

The Dutch XF4 ones were manufactured from 1957 - 1962

Thanks for the photo. Seems like a lot of work learning about the myriad variations of the EL34 - time to inform myself.

By the way, what are you using for your 6dj8?
