If anyone has a spare quad or source for inexpensive 300b tubes, please contact me or post here. Budget $400. Looking for tubes for my Electra Print 300b DRD monos. They say that those amps are build around specific tube brand but even if you shot me, I can not be a 100% sure what's used in these amps, so do not ask.(all it says - 300B in the middle of glass) Also heard that biasing is PITA with these amps.
