Unbelievable, the only thing I hadn't changed was the jack adapter!
I didn't have my HP's with me as I lent them to a friend and was using the amp with some cheap HP's. The amp didn't work and I panicked!
After a two days worry, it came to my mind that one the one thing I didn't try was the 3.5mm to 6.35mm jack plug adapter!

Oh well...lesson learned...

Thanks everyone for your help!

Should have mentioned you were using an adapter.
You need to use a good 1/8" to 1/4" adapter…a lot of them are junk.
Good to hear that you resolved the issue and it was a simple fix.

Yes, I should've mentioned it! I just don't know what I was thinking.

It's all good…most of the time I don't know what I was thinking either.

Hello
I have a WA6-SE and a Headphone Audeze LCD-3, last version 110ohms. I am using rectifier tubes USAF 596 and drivers tubes 6gl7, 6fd7 and 6rd7. My question is in which output (High or Low) is more technically correct to my LCD-3 (110ohms). 110 ohms is considered high or low impedance?
Thank you

You can use either. Measured impedance at the source for low on the WA6SE is 15 Ohm and the high impedance is 50 Ohm. Your headphones are pretty efficient at 104db/mW so you shouldn't have an issue with either jack. See which one is quieter and allows you good volume control.

Hi tube experts.
I am looking to upgrade tubes on my WA6-SE. The NOS tube I have identified, has a customs paper stamp on the glass. Do I try to remove this, or leave it on. Is it dangerous to leave it on?

i wouldnt its part of its charm

  Does anyone very lightly lube their tube pins with oil so their easier to install/remove, or is this not a good idea?

When i get new tubes in i always clean the pins with a fine sandpaper spray a bit of contact cleaner on wipe excess off that's all .

I do the same, but I'm thinking I'm going to put the slightest coat of Super Lube oil on the pins, but I just don't know?
