After several years rolling tubes like my life depended upon it - I have finally found what, in my personal view, is the best tube combination for my trusty WOO WES amp. They are:
4 x Telefunken ECC803s in the 6SL7 slots using the necessary adapters;
4 x Mullard EL37 (fat bottle variety); and
2 x Mullard GZ-37 rectifiers (fat glass variety)
Used with the Stax 009, this combination, for me, gives the most open ,musical and detailed sound I have every heard!
I wonder what tube rolling experiences others have had with the WES ?
