after service or tube(s) replacement, turn on preamp first. once it's completely up, you can turn on amp.
Preamp popping!
Salutations!
I have a problem and was hoping to use our collective experience to solve it..
My preamp (dared mc-7p) produces a VERY loud pop through the speakers approximately 10-30 seconds after I power it up. I'm now concerned about blowing a tweeter. I can even see the 12" woofers move.
Obviously I can just turn the dared on first, then turn the amp on after a minute or so. But that's just hiding the problem. I'd like to solve it..
Ideas? I've tried nothing yet. My first inking is to try replacing tubes.. Good idea? If so, shall I start with the power or signal tubes? Again, my inkling is to start with power.
Assuming that doesn't work.. What else could it be? Some kind of capacitor gone bad?
