No sound from a Shure MX412D/C

Bring a dynamic mic, the WH20 just needs a new connector put on it. The PG30 would need the MX1BP or the RK100PK with a phantom power supply.

Are you shure the speaker is good? Switch them around, If it still doesn,t work the problem is with the reciever,The output transister is probally fried,

See the following:

If you are good and familiar with a Kirby, the new generations are self propelled with a transmission BUT may cost you over $1500 US. They will be very familiar but easier to push, yet still vastly overpriced.
You might want to look for a deal on a used or refurb Generation 3-4or 5 or the new G6 in an estate sale or local newspaper. many people buy one then realize they can't run them and sell them off.
Or consider an easier running unit. if you want great quality, mainly for carpet, look for A sebo UPRIGHT

I"ve owned four pistol grip heads, and eventually they all do this. They simple wear out.

You can send it to Bogen, and for about $35, they'll ship you a reconditioned replacement.
