Anybody know where to get a replacement circuit board for a old Ungar 9000
solder station ? The number on the board is 3-015-329 or can anybody look on the circuit board and ID what I think is TR1 ? It is a TO220 case and is located near the bridge rectifier . I think it is blown but there are no ID markings on it so I can't ID it. So it could be a voltage regulator or just a plain old transistor. .. Thanks, Dick |
