what do you mean the bass is too loud?

I have an old 15" bass cab with a small piezo horn. The component wired in series with this horn had one of its lead broken off.<br /> <br /> Anybody venture a guess what replacement part I should look for?<br /> <br /> oldFartTweeterLessBassPlayer Walt

Walt, I'm sure someone else here can give you a more technically detailed answer, but I'll be first responder...<br /> <br /> That's a Ceramic Cement Power Resistor. (non-inductive)<br /> <br /> The value (I'm sure you got this much) is 20 watts, 8 Ohms with a tolerance of ±5% (J).<br /> <br /> I have know idea what the other numbers are but I'd guess manufacture date maybe.<br />

No more technically detailed info is required. It is exactly as described. 8ohm 20Watt resistor. Cheap and easily sourced. Mouser or Digikey.

These ceramic wire-wound resistors are fairly heavy; if it's 'floating' when you install it, place a generous blob of RTV 100% silicone between the resistor and the board it's soldered to. <br /> <br /> The GE or DAP stuff available at Home Despot, etc., in the caulk department is good stuff.<br /> <br /> The reason you need the RTV on there is because the mass of the resistor allows it to vibrate independently of its mounting board--and that's what fatigues and breaks the wire connections.<br /> <br /> Don't use hot snot because these resistors can heat up in use; hot glue will melt around 150-200 degrees F. Cured RTV can take upwards of 400 degrees F.

Only thing to add is that it's cermet resistor, not a cement resistor.

"Only thing to add is that it's cermet resistor, not a cement resistor."<br /> <br /> Hah!!! Damn auto-correct!<br /> <br /> Thanks
