What output tubes do ya'll recommend? If something besides EL34s will work, I'd consider them. Especially if they are drop-in replacements!

Your EL-34's look to be Amperex Bugle Boys, most likely made by Mullard, these tend to be rated as about the best of the EL-34 type. Why do you not like them? Are they weak, or do you just want to try something different? just curious...
