Hello All , I need a Circuit Drawing or Diagram for an Elma Ultrasonic Generator . The one that uses Vacuum Tube Valves like an old time Transmitter . It is a 'T 250 ' Model with the Serial No. BW 575933 & of 40 khz frequency . Last Built in 1973 ! I wrote to the Factory Service Department & they said " NO . Not available , too old " Watchmakers are all I know, so someone may be able to help with knowledge about this machine OR know someone who deals with this model . Thanks in advance Ken W. in OZ .
