Replacing MN1526 & MP1526 for 2SC5200 and 2SA1943

I am building Apex A40 amplifier. Can someone suggest me if I can I replace MN1526 & MP1526 for 2SC5200 and 2SA1943? It would be very helpful.

The reason is that it is very difficult to find original 2SC5200 and 2SA1943 here in India. Most of them are selling fake transistors without themselves knowing that the items are fake.


I have some original MN1526 & MP1526s from Sanken. (I guess so).

I know that 1943s are 30Mhz and Sankens are 60Mhz.
For this reason I feel that amp with Sankens might oscillate.


The other option is MJL1302 & MJL3281. (Even these I have originals)



Kindly suggest. It would be helpful.
