Hello everyone --

I'm having a couple of problems with new modules --

1.  On my new A-108 filter, the Emphasis knob does nothing, and
nothing plugged into the Feedback jack is audible at all either, no
matter the setting of the Emphasis knob.  Is there a jumper setting or
something that I can change to make this work, or might this be a
defective module?

2.  My new A-138c polarizing mixer arrived with no jumper on the pins
labelled "offset opt." as there apparently should be, so that Input 1
does not provide DC offset.  For those of you in the U.S., is this
jumper something I can find at Radio Shack?  I also want to get one to
turn the T&H to S&H on my new A-152 addressed switch module.

thanks!
