Just a little update. I've been listening to this little amp for four month's now with stock tubes and have bin really happy with it apart from the noise from the tubes when you look at them. I finally decided it was time to try a different tube but didn't want to spend too much on my first set so I bought two matched pair of these Russian tubes.
All I can say is I should have done it four month ago.
All the micro phonic noise of the Chinese tubes is gone and they sound very different. A much darker but kind of a wide open warmer sound.
So I am very happy and looking forward to being able to try different types and brands of tubes in it.
I also put in some little heat sinks on the op amp's. I didn't see that it could do any harm.
