Woo Audio Amp Owner Unite - Page 1564

Just to clarify, are people using the 596 instead of 5AR4s and 5U4Gs?  Is it a drop in replacement for those?  Any concerns?

I can't find a data sheet for the 596.

EDIT:  It looks there the heater current draw is the same so it should be fine.  Thanks Xcalibur255.

I'm using it instead of the 5U4G in my WA22. It is listed as fully compatible on Woo Audio's spec sheet as long as you have an adapter. I'm using Glenn's adapter and it works perfect with no apparent issues. I don't know all of the engineering details, but am trusting Jack that it is safely compatible in the long run.

Those 596's look like they were wrapped up nice and snug for their trip to their happy owners.  Mine hasn't left its spot front and center on the WA22 since I got it!  Enjoy!

x22! 

Please let me know what you like of an amp for your HD800. It would be greatly appreciated. I'm using a HeadRoom desk top now and thinking o the HDHV but would like your opinion on the WA22. thanks Dragon135-Seattle WA

Hi there,

i'm new here hehe..

having WA6 as my first desktop amp is surely something..

i'm pairing her with HD650 and dacport lx

the tubes used here were 6DR7 and GZ32(don't know the brand)

some little impression,

firstly, this unit is not a new one, the first owner already have this for about 1 month and has been used for about 80 hours

secondly, the first owner said that this unit is already modded as follows

changing caps, into unknown type 

cable that connect inside the amplifier, he said into copper, but still i don't know the brand  "he just said 'expensive?!' "

power jack, into "Frutec" at least this one i know the brand , and

the rectifier tube from stock 274B to GZ32 (and again, i don't know the brand)

i'll post some picture as soon as possible, so that maybe someone could help me identify that "unknown" brand..

okay, so a little impression:

i've been hearing these amp for about 6 hour, so hope i could give a nice impression here.. hehee

So, normally i used to listen to my HD650 from Govibe Vest with Dacport LX as source,

at the first minute i hear from WA6, the impression here were just like it's different!, but not give me some chill or WOW feeling (i listened at local headphone store)

so i continued to listen about 2 hours using some vocal and jazz album, and i just fell into some deep nice relaxing sound,(at Home)

at some normal volume (about 11 o'clock) the impact of the bass are not so WOW, but at around 14 o'clock, this baby just starting to show her prowess

the impact is just so nice, yet not making other frequencies loses their nice smooth feeling, this is truly something that i'm not getting from vest + lx combo hehe..(what do i expect? hehe)

the best things that make me not regret getting this amplifier is this amplifier could make my ear felt refreshed from my old set of music XD

so, finally i just said that this amplifier really making my HD650 sound like really 'reference class' hehehe..

Sorry for my bad English, and hope i could post some picture soon..

Question for the 596 Club:

I got my 596 a few months ago (thanks SO for selling me on it and pointing me in the right direction for acquisition ) but for a number of reasons I won't get into here, I did't actually try it until this weekend.  I know, shame on me, but be assured it was out of my control.  I also got the adapters from Woo for my WA6SE (beautiful piece as always).  I swapped out my EML 274b on saturday and plugged in the adapter and then the 596 on top.  When I connected the external leads, however, I noticed the connection is loose!  Very loose, actually.  I was a bit nervous, as you can probably understand, but I fidgeted with them for a bit until I got what felt like a relatively stable connection.  While standing a bit away from it and half-flinching, half-wincing I fired the WA6SE up.  Lo and behold!  It worked fine.  I let it warm up for a couple of hours and then listened for about 4 more hours.  It was rough going at first, sounding very harsh and fatiguing to say the least.  By the end of the session it was sounding much, much better.  Not up to par with the EML yet but I guess a rugged tube like this one needs some time to break-in.

So the question is: are the leads supposed be loose like that?  Even though it worked I am a bit hesitant to try it again until I know this is normal (or not).  Anyone else with the Woo adapters have this issue?  With Keph's adapters?  Greatly appreciate any thoughts from you guys.

Can you explain what is loose?  Do you mean the part that slips over the metal leads at the top of the glass?

I have a 596 and the Woo adapter.  The connector from the adapter to the one of the leads on the top of the 596 is a little loose but hasn't been a problem to date.  It worried me a bit at first as well.

Yes, exactly.  The cap/connector on the end of the wires from the adapter base is in essence the 'female' end of the connection and the pins that stick out of the tube the 'male' end.  If you look at the female end, this socket is of a larger diameter than the male pin.  Much larger, I would say.  Definitely not a solid connection.
