Help! Bright switch for Weber Mass

[Stratin2traynor]

I have have an older model Weber Mini Mass without the treble switch. I want to add a treble switch. I emailed Ted Weber and he basically told me what to do. I can do it easily if I knew exactly what he meant!! Could anyone explain to me what this means...

From Weber: :"Yes, just put a switch in series with a 20uF bipolar capacitor between the two top terminals of the bypass switch."

I have the switch and cap and I know what a 20uF bipolar cap is, I just don't quite get how to add a switch in series and can't seem to find a reasonable explanation (with diagrams) on the net. Seems like a relatively easy mod/addition.

Can anyone clarify this for me?

Just to clarify there are six terminals on the bypass switch 4 of which are occupied. The two terminals he is referring two are simply jumpered.

:bow:

the two jumpered terminals are the bypass. Are you sure that's where he means?

[Stratin2traynor]

Well those are the two top terminals of the bypass switch. It would seem to me that the cap should go at the other end.

[dwagar]

that would make sense to me too. You would want to switch through the cap when the circuit is on, not off, right?

[Stratin2traynor]

Right. I plan on putting a on-off-on switch to have two cap values. One of the values is 20uF I'm not sure what value I should use for the other...47uF???

think of it this way...

the capacitor allows some treble sound to pass, while blocking the lower frequencies.

you want the signal to go through the capacitor only when the switch is closed. when the switch is open, no signal can pass through the capacitor. so you want the switch to control wether or not signal gets into the capacitor.

connect one side of the capacitor to one of the terminals, the other side of the capacitor to one side of the switch, and the other side of the switch to the other terminal.

does bipolar mean non-polarized? if so, it doesn't matter which side of the capacitor is which.
