Hello - thanks in advance to everyone for their help and guidance. I have several SEBRA RF Generators that are used in conjunction with a sealing head to seal off PVC tubing in medical device assembly. The generators are starting to fail (transformers, resistors and 10 turn dials primarily), and I am hoping to get some help locating a repair facility? The manufacturer is now VANTE, and will not help with repair or referrals. Any help, comments or direction is appreciated!
