Hi Mr. PsVane.
Just bought a Melody PRO88 MK2 which has 4 x KT88 and 4 x XF184 1 x WE407.
What PsVane tubes you recommend me to boost the SQ?
Only change the 4 power tubes to a KT150?
Or stay linear with KT88 or 6550 but then much higher quality?
Will change the 4 smaller XF184 bring me anything ?
Thx in advance
