Nor am I, if I'm honest, but it should be fun, and it won't cost much, so why not give it a go? And if it only shows that there's no difference between PRP and the cheapo Brazilian no-names I'm using then that's better still, right?

And I've already learned something from you and juma this evening, so that's good too...

Does this gain stage would change the sound of the B1 ?

It's very easy to test it.
I like BF862 better than 2SK170 - you might have different preferences...
