MT DE700 DRYER
Hi Paul looks like you got good dryer. The ozone lamp is in a good location as you are not supposed to look directly at them. Its location allows the air coming into the dryer cabinet to pickup the ozone gas generated by the bulb and carry it over the clothes in the dryer as they dry. When the ozone bulbs are wired in series with the 40 watt drum lamp as it is in this machine you can just bypass the socket so the drum lamp will still work with no ill effects. Ozone bulbs contain mercury and are hard to find new, they were used in many old air cleaners and even some early ventless range hoods they have a very long life so they can be found. If you use the ozone lamp its best to vent the dryer out side as the ozone gas thats generated can be irritating to your nasal passages etc. The gas can also degrade rubber parts. It looks like your dryer still has the old pot-metal motor pulley, these would tend to wear and not turn the drum well with a heavy load, these should always be replaced if the sides of the pulley grove are rounded at all, they should be straight and flat. This was one of the most over looked mechanical problems on early HOH dryers, MT changed to a steel pulley in the late 1960s or early 1970s, all replacements are steel and they are all interchangeable.
