Hi All,
 
Feel like I'm having some issues with my headphone input on my WA6. 
I am plugging my HE-500 into the jack and all is well. After a few minutes however, the sound on the left side of the headphone starts to cut out slightly and sounds a little but muffled. I'm sure it isn't the headphones as I have plugged them into a few other amps and they have been perfect for extended listens. 
 
Has anyone experience this at all? Or have any ideas?
 
Thanks

1. Try a different set of phones (even crap ones) to ensure it's your amp and not your phones/cable/connectors
2. Try different tubes or reseat them to ensure they're fully connected. I've had a similar experience to you when one of my driver tubes had a defect... particularly it was a pain because the issue only showed up when combined with certain tubes/rectifier combo + had to be running a certain amount of time before it could be heard

Headphone output. 

Sound like a tube issue…switch the left tube with the right tubes and hear if it happens in the right channel.

Waiting for my Woo WA6SE with upgrade tubes to sophia princes and still indent for 6fd7

Can a 5Y4G rectifier  be used in a WA6

Not so sure?
Here is the; Woo Audio Compatibility Chart.
I don't see it here, unless I'm missing something?

So, I received my beautiful black WA6 on Monday. I was expecting it to take weeks, but it took five days from the day that I ordered until I received it. No buyer's remorse at all, I love this thing with my HD650.
 
The only problem is that I'm stuck with the stock tubes. I ordered a Brimar from Langrex the day that I ordered my amp. To anyone else in the US who ordered from them, roughly how long did it take to receive it? Did you ever receive a shipping confirmation? I never received anything from them after the payment confirmation. Not sure if I should email them or not.
 
Also, regarding drive/power tubes, I'm interested in trying out some different ones. I'm particularly interested in the 6SN7 tubes after reading through this thread. Does anyone have experience with the option 3 offered in Woo's store for the 6SN7GT + adapters? 
 
This is my first tube amp, and a huge upgrade from my Magni. I already love it, and I can't wait to start messing with tubes, but it's confusing knowing where to start.

Congratulations on your WA6!
I ordered a Brimar 5Z4G from Langrex (no confirmation) and it was here (N.Y.) in 1 week!
The Brimar is an excellent value/tube! Don't bother buying the Woo 6SN7's, but I do recommend buying the 6DE7>6SN7 adapter from Woo (which you will need)…buy some NIB/NOS RCA/Sylvania 6SN7's from a reputable company or eBay. I bought all of mine from eBay. The combo of these tubes together is simply amazing…especially for the price of the Brimar. I also have the Sophia Princess/Phillips Mini-Watt GZ32 which I happen to like both also, but the Brimar is a better value. The Brimar is the only rectifier tube which comes close to my UE USAF-596 which are not too easy to come buy.

I ordered 5 tubes from Langrex on 2/11 and they were on my porch (Seattle area) 2/19. All were
nicely wrapped & in white boxes, and all tested excellent. No confirmation or tracking, however.

I also picked up some Brimars, too much peer pressure! They are incredibly good for the price. If I didn't already have so many rectifiers I would have picked up a lot more than the four I did.

Thanks for your help guys. Had about a week of testing and the issue mysteriously stopped. Will have to listen out for in the future now that I know some solutions.
 
Have another question. Has anyone hooked up a DAP to their amp at all? Wondering if my DX90 would be worth being the source and the WA6 the amp as a bedside rig.

Does anyone have any recommendations on a dac for the Woo WA6 and HD650s at $500 or less?  I love the sound of my WA6 and don't want a dac that is going to change the sound very much.

I am using a PS Audio Nuwave with my 6SE and it is damn good. I have an LCD 2Fazor and I still share 50% of my head time with the 650. I love the combo. Can find the Nuwave for around 500 used
