I guess I didn't know there was such a thing.
Too bad. I have the same Tung Sol 6SN7 in my WA5 and the base came loose on one of them. Still works fine but I have to be careful to grasp just the base when inserting or removing. The pins were pretty corroded and the Woo socket is pretty tight. So I polished the pins. But I am very reluctant to change out those tubes now. Which is not a giant problem because I don't know of a better 6SN7 for the Woo anyway.
Do you?

Check out the mullard ECC31's they are not too high priced you can get a great early 1950's pair for around 260. much finer sounding then any 6sn7. When I tried them & the 32's 35's I was sold never going back..

I use super glue with my loose base tubes just put a little all around where glass meets base  so far they stay glued

Good to know. Thank you!
I knew a fresh way to spend money on audio was just around the corner!

So I snagged a pair off of eBay for $244!
I love Mullards. Have the CV4003s in my PrimaLuna.
Can you recommend a source for an adapter?
Thanks for the tip. :)
 
Anybody want a used Tung Sol with a loose base? :wink:

I get the impression based on test results I see listed for various ECC31s that they have lower output than the 6SN7.
Do you think that is a problem with my power hungry Abyss phones on the WA5?

  Yes I am lol. My problem is that the noise (which is tolerable though) keeps existing, without source.

 
Check the settings. What headphone are you using? Most headphones are LO power and LO Level setting.
