after readying many reviews i've decided on this two, can someone who's herd this two amps share their thoughts on which might be a better match for the callistos
You should first try the stock tubes and see how you like them. If you really want to upgrade, then you should go for the EI 6CA7 or the Mullard EL34 but they are very hard to get.
Sjevo, i bought the amp used, it sounds fine but the tubes are at least a couple years old, since i'm replacing them anyway might as well buy the better ones, now how will the sound on the amp improve with this tubes respectively, thanks again
