Hi
I´m messing around with a La-4, having lot of issues, the BD 139 & 140 Transistors run so hot, so I thought I´ve soldered it backwards.
They don´t have E-C-B names in the pins, the 139 show A0, T & Ax, while the 140 has A8 (or B I`m not sure), T and Ax pins.
I think T and Ax are C and B, but I´m not sure, could somebody confirm this?
I´ll try to make a decent photo with my phone and upload it if it could help...
Thanks Guys!
