Not sure where to post this, sorry if this isn't the correct section...
Can anyone offer up a good site or article that addresses which tubes can be substituted for others.
I'm really only concerned with a few:
1. Can EL34's and 5881's be interchanged? If not, what could I use in place of EL34's? 5881's?
2. 12ax7 = ECC83, but what others will work?
3. 12au7 = ECC82, but what others will work?
Thanks
