Ungar 9000
 

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
..
Thanks,
Dick
