Yes, absolutely. Without the necessary knowledge, this can be life-threatening, such as when discharging capacitors. We have basic knowledge in electronics but are not specialists in amplifiers.

Thank you! We measured the resting voltage of all the old MOSFETs (except for the disconnected defective one) and then adjusted the bias of the new MOSFETs so that it is not higher in any of them compared to the old ones.

We replaced all the Mosfets since one was defective and tried to repair the DI out. Check out posts #971 to #975.

My Mesa Boogie Titan V12 is finally repaired and working flawlessly again. My guitarist and I repaired the entire unit ourselves, but unfortunately, the component of the DI box that we replaced failed again on its first use. We plan to fix that as well. Additionally, I bought four Mosfets as...

Ok, thank you. Would it be better not to change anything and continue playing with one less MOSFET each (positive and negative)? I have already played like this for an entire evening.

Thank you for the information, and yes, I will renew all of them. I will need 14 pieces of ECW20N20-S and 14 pieces of ECW20P20-S (including 3 spares each). For my understanding: I will measure the Vgs and then order the appropriate ones. Unfortunately, the selection is only based on min/max...

Hello everyone, I am new here and came across this forum while repairing my beloved Big Block V12 Titan. As already known, Mesa Boogie no longer provides support for this amp (unfortunately). We have already identified the problem (one MOSFET on the positive side burned out). We have removed...
