thanks! then NOS tubes would be the most appropriate (though it should be almost impossible to consider a new tube or one in a good condition from 50s or 60s).
Does a tube need the break-in hours?
Most probably not, but not sure why :)
Does anybody know a good substitution for 12AT7WA tubes? I have bought 8 of them about 10
years ago for Manley Stingray. Now, when I need a replacement, none of them are good
(ones are labeled by Manley others are Philipps).
(An almost 20 years old Stingrey remains in a good shape.)
