A METHOD OF SEALING CONTACT REEDS IN A GLASS TUBE COMPRISING THE STEPS OF: SUPPORTING THE GLASS TUBE AND REEDS AT OPPOSITE ENDS OF SAID TUBE IN A VERTICAL POSITION, ALIGNING THE TUBE AND REEDS WITH A HEATING FIXTURE POSITIONING BETWEEN THE REEDS, RELEASING THE TUBE TO FALL INTO THE FIXTURE AT A PREDETERMINED POSITIONED WITH THE ENDS OF THE TUBE ENCLOSED BY RESPECTIVE HEATING ELEMENTS OF THE FIXTURE. CLAMPING THE TUBE IN THE FIXTURE, INSERTING THE ALIGNED REEDS INTO THE RESPECTIVE TUBE ENDS TO FORM A PREDETERMINED OVERLAP AT THE INNER PORTION, ESTABLISHING A MAGNETIC FIELD ABOUT THE TUBE AT THE OVERLAPPING PORTION TO MAINTAIN THE REEDS IN A CONTACTING POSITION, HEATING ONE END OF THE GLASS TUBE TO SEAL ONE REED THEREIN WHILE MAINTAINING SAID REEDS IN SAID CONTACTING POSITION UNTIL THE SEAL IS COMPLETED, RELEASING THE REED AT THE SEALED END AND TURNING OFF THE HEAT THEREAT, HEATING THE OTHER END OF THE GLASS TUBE, REMOVING THE MAGNETIC FIELD AFTER HEATING THE OTHER END OF THE TUBE, ROTATING THE OTHER REED INSIDE THE TUBE ABOUT A CENTER WITHIN THE OTHER HEATED END TO ESTABLISH A PREDETERMINED GAP BETWEEN THE OVERLAPPED REEDS BEFORE COMPLETING THE OTHER SEAL, RE-ESTABLISHING THE FIELD AFTER ESTABLISHING SAID PREDETERMINED GAP, TURNING OFF THE HEAT AT THE OTHER END, ROTATING SAID OTHER REED FURTHER TO RESET THE GAP TO THE POSITION AT WHICH RHE MAGNETIC FIELD CLOSES THE CONTACTS, REHEATING TO COMPLETE THE SEAL AT THE OTHER END, REMOVING THE FIELD DURING REHEATING, AND TURNING OFF THE HEAT AFTER SEALING THE OTHER END.
