Have two EQT's that have " 0 " voltage on the output RCA. Everything seems to be fine except that there's no output signal. I have one that has an output signal of about 1.6V and it works properly. Any ideas on what is wrong with the internal workings of the EQT's ??

Is the PFM modules installed inside... even if not using the subsonic block, there must be a module installed... if it is there, check to see if it is pushed in all the way

I have seen the gain POT burn out and be set to "off", thus giving no out put voltage.

Another way to go is to open it up and trace the signal through the system from input to out put and see what component may be causing you trouble, like if an inline diode/transistor or whatever is bad.  It is a tedius process though, but I have repaired CD players and cellular phones that had oddball parts bad this way.

good luck!

Thanks for the suggestions. I will try and trace the problems and check the PFM modules to ensure they are fully connected.
