Vintage McKenna Kleaner Ultrasonic Watch Clock Cleaner FOR PARTS OR REPAIR ONLY

Vintage McKenna Kleaner Ultrasonic Watch & Clock Cleaner, FOR PARTS OR REPAIR ONLY. I bought this at an estate sale. I'm not experienced with this item.

I couldn't get it to work. With the power switch on the fan blows warm air into the dryer. I opened the bottom panel (see photo) just for a look inside. It uses vacuum tubes and I noticed the large tube doesn't light up.

I removed it and could hear rattling inside it. It appears to be a rare item.

I cannot offer any technical advice or help on this item. Professional repair and operation recommended.
