Fixed Bias KT 88 amp power tube replacement


Recommended Posts

I have an Oldchen K3 KT88 amp.  It uses four Psvane KT 88 tubes in the power stage and the preamp has 6NS7 X 3.  If I replace the power tube with another matchd quad set, does the bias need adjusting?  The new Shugang Black Treasure KT88 tube has mV 35.  The current Psvane tubes are mV 45.
