problem with class AB amp and class D amp

[namuxtree]

How do i fix these? I understand there are some amp gurus out here on TB and i'd like to ask for your help.

the AB turns on but output is very low? theories?

the D does not power on yet the fuse is good. ideas?

Sorry, my ESP isn't working. I can't tell what brand and model they are, and can't see their symptoms. Maybe another amp guru has his or her psychic powers up and running.

Isn't it obvious? The AB one needs to have its caps rotated, and the class D one needs a new dilithium crystal.

my ESP is working perfectly, but i still can't figure it out.

BTW, does anyone know why my wife's car won't start?

GAS?????

Your flux capacitor is not getting enough gigawatts.

Jimmy M suggested a broken framistat in the globulator in another thread.

i had GAS but i took some beano for that.
thanks for the suggestion though.

That's just a myth. Jimmy is so obsessed with his Ampegs that he thinks all amps have framistats.

 

[BassmanPaul]

Well Bongo, as you know, the framistat controls the amount of power that the globulator can draw from the alternate reality at any moment in time. This power is measured in Frams. Obviously it has failed as the Class D amp is switching on but receiving no power. You can tell that the globulator is working otherwise the amp would have disappeared into a vortex connecting the various dimensions.

And before anyone brings it up, the framistat in a class D amp is not necessarily digital!

The hamsters need food Cap'n. I don't think they can take much more!

In this case Bob you should take the bass back to the manufacturer and have the wiring checked out!

It's all ball bearings these days. I check that first.

LOL great one Bob!

I was hoping someone here might tell me how to fix it.

Not enough information, but...

both need to be seen by a qualified tech. Probably looking at a bench fee of ~$65 each plus addt'l labor & parts (like a deflostigator, boards, MOSFET chips, dip, etc.)

What are the brands, models, approx. age?

I've seen this happen in dirty power situations. The OP could definitely use some Fram filters (available from AutoZone).

Well played.

if i didn't give enough information you guys should just say so and then stop. No need to veer off on senseless chatter....anyways...

I have an Eden WT-800 and a Markbass Little Mark Tube and my friend has the exact same setup. Both my amps are fully functional but my friends' amps are both not. We've opened up mine to check for any obvious flaws there may be that our untrained eyes can see. So far no luck. UPDATE* Am i to believe that the regular LMTube is an A/B?
