Pioneer Transistor replacement

[Mrcoolest123]

hello!

I just got a new piece of gear for my collection, a pioneer sa-710. Got for a nice price because the seller told me it didn't work and wasn't able to repair it. I have some knowledge on electronics so I took it as my project to repair it.

I already found the replacements for the burn diodes and resistors, but I'm unable to find them on my own due to lack of knowledge on the area.

So that's why I am here! What would you guys recommend to replace the following transistors?


2SC2525

2SA1075


2SC2275

2SA985


I found the thread of another guy from 2018 saying he replaced those same pieces with the following, but I searched the web and unfortunately they have been discontinued. hope it helps


2SC2525 —---------- > MG6330-R

2SA1075—---------------> MG9410-R

Thanks friend! I will look in the web to see if I can get these transistors.

Just to know, because I'm no expert, Will it be necessary to make any accommodations on the circuit board to fit them ? Like, will I need to add extra resistors or capacitors to fit the new parts in? Or this is just a case of swapping the old to new ones ?
