I have one, and agree with Albert--just remember to do the drill for each channel, as the Fluxbuster only does one channel at a time. Plug it in, insert the RCAs, tilt the rocker switch towards the channel to be done, watch the flashing lights till it indicates "done", then repeat for the other channel. If you have a P-mount cartridge, that's what the raised portion on it is for. Good luck!
