Quote: Sorry... I can see I made a mistake in my previous posts. The WA2 actually needs 2 driver tubes, 2 power tubes and 2 rectifiers. Matched pairs now make sense. Thank you and sorry for the confusion   :-)

Quote: Totally understand that two tubes need to be matched .. but would a matched pair itself need to be matched with the second pair as well?

Hello everyone :)   I just ordered a WA2 and can't wait to get my hands on it. :)   I am however a bit confused about tube matching... would someone be able to help? Basically, I understand that the WA2 has 2 power tubes, 2 rectifier tubes and 4 driver tubes. If I were to buy replacement...

I got the WA3 back yesterday and I am happy to say that it now works just fine :). I am very happy I did not turn my back on it.   It turns out that the power tube supplied was faulty. The crazy thing is that the additional tube I purchased (tested etc) was also faulty. So when I was testing...

Quote: Thank you very much :)   Decided to keep the WA3.. I just hope it will work fine when I get it back from Jack   Best Yiannis

Quote:   Greetings reeltime and thank you for empathising :). The amp is now back and I am faced with the dilema: Do I ask for a refund or do I take back the repaired WA3. I would love to have a working, noise-less WA3 serving as a preamp to my digital amplifier. After my experience...

I have finally contacted Jack and asked for an RMA. The WA3 is going back :-(. I have the highest praise for the particular amp so I can only conclude I have been very unlucky. Cost to ship back: $40... Ouch

Quote: Hi,   I have completely disconnected the WA3 from the sonos to see what happens. In other words, the only connections are WA3 power and speaker cable connections. The problem remains unchanged sadly.    One other thing I have noticed is that the woofer cones move slowly in...

Quote: Hello reeltime and thank you very much for your helpful suggestions. I actually checked the speaker connections and they are fine. I have a small integrated amplifier sitting on the side of the WA3 and I just connected my speakers there to test. I performed the test a number of...

Hello hodgjy,   I could tolerate the humming as background noise... The problem I am experiencing is something else altogether though. More like sudden loud crackling and popping sounds that are quite uncomfortable to the ears. The music mutes momentarily when they occur...   I wish the...

Hello rosgr63   Thank you very much for your response, I greatly appreciate it :-). Unfortunately I don't have a tube tester so I would not be able to check. I was able to rule out the power tube as I have a spare 6080 (new). I swapped the one supplied by Jack and the problem remained.  ...

Hello everyone :)     This is my first post in this forum. I have been reading this thread for a long time and needless to say I was very impressed with Woo Audio amps. About 4 weeks ago and after tons of research, I went ahead and contacted Jack. I ended up ordering the WA3 which got...
