derrickdj1 Posted February 5 Share Posted February 5 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.

Schu Posted February 5 Share Posted February 5 if it's not auto biasing, I think it should at least be checked. 1 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted February 9 Author Share Posted February 9 Yesterday two surprises, Marantz NR 1200 and Oldchen K3 KT88 , 2 channel network receiver and tube amp respectively. They both sound great right out the box. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted February 9 Author Share Posted February 9 I will pair my Focal Aria 926' for 2 channel listening with the Marantz NR1200 or the tube amp using a Niles DSP1 A/B speaker selector. A simple system. Quote Link to comment Share on other sites More sharing options...
