BIAS regulation Electro Harmonix KT90 vs Jinvina KT90
Hi to all, I am new in this forum, I own a MingDa MC368BSE audio amplifier and it is time to replace the final tubes, I was suggested to replace the original 4 Jinvina KT90 with a selected quartet of Electro Harmonix KT90EH; I wonder if the BIAS will be OK if not exactely the same (this amp has a fixed BIAS).
Thank you in advance for your kindly replies. Luigi |
