To be honest, the tube glow is so warm it puts me to sleep. I have so many CDs where I have only heard the first three tracks

Many times during the burn-in period, I ran the amp for 12-13 hours continously without incident. It did not seem any hotter at the end of 12 hours than 10 hours. Sometimes I would turn it off after 12 hours, let it cool down for an hour or two, and then run it for another 8-10 hours. It has shown no ill effects.

One more question. I just got WA6SE from other head-fier. When I tried it at first with Sophia and 6EW7 combo, it worked really fine. When I went back home and tried it again, it couldn't work and I found a fuse was dead. I went to Radshack to get the replacement. just turn it on and the Princess flashed inside!

and a fuse is dead again. -_-"

I don't know what's wrong with it. I connect the WA6SE with Signal Cable power cord. I guess that shouldn't be a problem, isn't it?


-------

EDIT: after changing to another combo, the problem is the Sophia which makes the fuse dead. Everytime I put the Sophia in and turn the amp on, it flashed. I guess I need to contact Jack Wu for the clarification.

Jack made a change in the design of the SE late last summer to make it compatible with the Princess - changed an inductor or resistor value in each circuit. Earlier designs typically caused a flash in the Princess, which may be what's causing your issue. You may need to return it to him, to be updated.

There's an extensive discussion of the change in one of the Woo Audio 6 threads - maybe this one.

It seems to operate fine with other rectifiers - but, the Princess has different requirements.

Thanks Gradofan2.

I already got the response from Jack. he asked me to send the PSU unit and the Sophia back.

 

[sclamb]

Don't worry. Jack is good on this and you will get the PSU back working perfectly with the Sophia.

Yeah...

... that's one of the benefits of buying a Woo Audio amp, which may not always be fully appreciated: their elegant design and construction, and the exceptional customer service... unlike... "some other amps / vendors we know."

Confidence and peace-of-mind are worth a lot!

You ca find how to fix it easily by yourself in this thread in p.56-57, from post #837 that what sclamb was having the similar problem then solved.

Hope this help.

 

[sclamb]

Yes, close them pins up a bit and it will grip the tube better. I would only bother doing this if the sound is being affected.

 

[yoff]

Thank you for your replies .

I think I'll just spring for a WA6SE with the upgrades and enjoy it for a few years instead of rushing to go balanced. It's way too much money because on top of the amp, I'll have to get all the headphones recabled. I like what I've been hearing about the WA6SE.

 

[shellylh]

You could always go for the WA5 LE, that was my "compromise."

Where I can get a pair of RCA fat bottle 6FD7? I couldn't find it on eBay and at tubedepot.com, they only mention as NOS-tubes.
