I've been using my WA6-SE 2nd gen with the 13EM7 since april without issues. Probably they changed something at some point that is generating the issues. I bought the amp a year ago (with the black Friday discount).

Here it is...

There's a buzzing noise from the power supply side when on, you can easily hear it at 50cm... Fortunately, headphones are dead silent. Anyone had the same issue?

Mine is quiet.
Maybe 220/110v switch in wrong position?

 

[Geekinside]

Correct position of course (230v for me) otherwise it would have damaged it.

Probably the transformer became lose during shipping. Contact Woo for support.

 

[Geekinside]

Will do

 

[Geekinside]

So that's what I have...



Tried with and without a source, different power cables, different power plugs. It's audible from 3m in a quiet environment. Just emailed Woo with these infos. Let's see.

Yes but it wasn’t a woo it was Valhalla 2 it buzzed quite loudly in a quiet room, I never figured out what was wrong it just got returned.

Hello, I wish to buy a tube for the WA6. Brimar 5R4GY.
I see there are multiple versions, which would be best?

For Brimar CV717, there are multiple markings, V27, V23, V30. Does this count?
V27

Here is what you're looking for; NOS Brimar 5Z4GY for your WA6.

 

[filip sebastian]

Ok,and V23,27 or V30 are not good?
What are the differences between https://www.ebay.com/itm/382560247312 and https://www.langrex.co.uk/products/5z4gycv1863-kbfe-stc-brimar-nos-boxed/ ?

What is the difference between regular WA6 and the SE version?

What is the difference between regular WA6 and the SE version?

You can see a comparison of Woo amps here. The main difference is that the WA6-SE is bigger and has more power, plus the benefits of having the power supply completely decoupled.

I`m confused. Can be rectifier source of problem? Noise goes from side to side if i swap right and left tubes. I paid for new rectifier, but I have bad feeling.
This is respond from tech support.

Dear Roman,

We tested your WA6-SE and 13EM7 tubes (with our rectifier tube) extensively and could not find any noise issues. Since we don't have your rectifier tube, we recommend to purchase a new rectifier tube from us to be returned with your amp and tubes. This way, you have a reference point upon arrival knowing that the entire system was tested and noise-free.

- Inspection fee waived, $30 return shipping by FedEx + $35 rectifier tube

 

[Russianguy]

Can be rectifier source of problem, if stock tubes making no any noise,
