The ECA - table shows the BD245 and BD246 as direct replacements. As fas as I know you guys dont have the BD-typed power transistors overthere. If it was the output stage you could probably use TIP35C and TIP36C transistors.
I tried to contact you but the board says you don't accept e-mails. I need two pairs of the 2SA1265N and the 2SC3182N.If you have them and feel like selling them please get a hold of me at email@example.com .
