This PH7 comes with a remote control which allows you to change the load at any time to any of 47k, 1000, 500, 200 or 100 ohms. The remote also has buttons for hours, display, mute and mono." My current Reference, it is the finest phono preamp Johnson has yet devised or I have heard " This was a quote from one of the best magazines first review of the PH7. The unit is all packed up and sealed ready for shipping and I forgot to check the hours. I apologize. This was a trade and I did listen for several hours before packing it up. Another great great phono preamp by Audio Research.
