Post Subject: VR2 issue leading to jump in current on 6C33 tubePosted by S.yorke on: 10/6/2018
Dear Romy,it had been a while before I hv return to your goodself and here.The Meliq had been built according to your circuit. However, after a few days' breaking in period. The VR2 have issue and causing sudden increase of current... I think it might be the quality of the Bourn. Here is my question. Even if I had the VR2 replaced, it is like a time boom while I was enjoying music in the near future. Also, if the 6c33c itself is not perfectly match pair, how should I adjust and match both channels? If I were to adjust VR2 , do I aim to have both channel balanced in output or voltage at grids?
Is there a failsafe method to alter this part of the circuit in case this VR2 Failed again?
Thanks in advance.
Best Regards,S.Yorke
