DSL40CR

Dear,

I have a Marshall DSL40CR here with crackling/popping noise, I have already checked the tubes in a Hickok TV2C tube tester, and they are good.

The master1 and master2 are closed. I realized that when I removed the Valve 4 the noise would stopping. So I searched around v4, and noted that the noise comes from resonance circuit, if I removing C138 the noise stopping, above this capacitor there are 105V, I swapped to 10uf/160V but the problem is the same, could you help me, please ?

Thanks & best regards.

Hello Geovane,

With regards to your DSL40CR as this unit is still under warranty we would recommend that you take it back to the dealer it was purchased through so they can look at it for you.

Kind Regards
