thanks for the info longbox55.I didn't realize that there would be a difference in a 55 235 head and a 56. The reason I was wanting to swap to a electric unit is because the original one went bad, all the gas came out of the tube. I then picked up a original supposedly working one that did not work. So I figured why not go to a electrical type of unit. The electrical ones seem to be more duarable then the tube type and don't cost as much.
