The spec sheet says all tubes should be JJ's. I just discovered all the 12AX7's in my amp have a small '8J0' printed on them, and the 6L6 power tubes are completely unbranded. Are these actually JJ tubes then?? Their valves are always branded to my knowledge, amp bought brand new from a dealer, box un-opened.
Amp sounds fine, just obsessively curious
