I recently found this' Mazda ballast (the normal 40W Mazda ballast is for comparison):
The ballast is for 2 TRF lamps with 40W. (Has anyone such tubes for me?) The date code is H12, someone knows how old it is?
About another forum I found the same drawing:
Does anyone have a wiring diagram for this ballast and someone know what the second small ballast is? Maybe a normal for 40W?
And how rare is such a ballast?
Is PCB inside?
