I'm pretty sure that there was a group buy for Wima caps from them way back during the first beta run.

They don't have the 22.5mm lead spacing version in stock right now.

May be a bit thick, but perhaps Runeight could provide a waiver?
 
I use a lot of Panasonics (kinda like these), which require just a bit of bend to fit well - worth a shot, and a bit closer to home.
 
Oh, and I do love the logo. Pure win.

BFC246860104 is just slightly larger, I think it would obstruct d5 and d6 unless I bottom mount those. Those panasonics looks good though, I'm grabbing a set just in case. I'm going to guess that the polyproplyene cap is there to provide that a little bit more performance over polyester cap? 
 
btw, nice DP

I love the new custom title!  I need Nate to give me a Cavalli Audio title too.

Actually it was these folks. Give them a call. They were very helpful in supplying us the WIMA caps on the original group buy.

I tried ordering online using their shop before, but I couldn't get access to the cart for some reason...

Only postingto give you an idea of what's under the hood of HeadphoneAddict's eXStata. Not the neatest,but it a lot of wires in the rear of the amp.
There's a Placcid PSU for the volume control board.
Teflon jacks (very sweet btw), and Volume control board and control software by Luvdunhill.
 
Boards were stuffed and tested by Alex Cavalli.

I had popped the hood and took photos tonight, but you beat me to it.  I'm packing up for the Colorado meet, but will hook this up in the AM to my CDP-8 on the kitchen table and give it a listen.  Thanks!
 
In comparison, here is my Hybrid amp:

I knew it was T-something, and TTI came up first on a Google search. Thanks for clearing it up!

Hi all
 
Finally got my act together and started building the tubed eXStata a couple of days ago.  I've finished the power supply and decided to test it before going on to assemble the amp boards.  All looks well with the following readings:
 
Line AC: 237V
Secondary AC: 252V
T1 to gnd: 328V
T3 to gnd: 327V
Rail voltage: approx 299V -/+
 
Most of the components are mounted on the amp boards and I'm now testing the Jfets.  Out of the 20 I bought I got the following groups >10mA:
 
10.9
11.0
11.2
14.3
 
and:
 
18.8
19.7
19.8
20.9
 
I guess the 2nd group is my best bet but the quad range is above the recommended 10% at around 11%.  Is this OK to use these (I hope!) and if so would I combine the 18.8 with the 19.7 and the 19.8 with the 20.9?

[wink]

marcus1,
You did well,
I got 40 of 'em and got 1 set of 4 within 10% and 3 lots of 3 within 10 percent.
 
13 out of 40 above 10mA  - not so good
Half of them were 7mA and lower.
None were over 17.5mA.

 

[marcus1]

Just trying to make sure I understand the 10% range recommended for the J271 jfets. 
As far as matching the jfets within the 10% parameter goes, does this mean that (for example) Q1L/Q1R must be within 10% of each other or that the four jfets together must be within the 10% range?
 
cheers
 
Tim

[ujamerstand]

In this case, all four jfets should be matched within 10% to minimize channel imbalance. 

 

[marcus1]

OK, thanks ujamerstand. I've ordered some more jfets to try and get a closer grouping.
