Does anyone know where I can get transistors for a 30 yr old Spectral amp DMA200?

Stephen Sank diagnosed the problem with my friend's Spectral DMA-200. There are several DMOS FET that are bad or about to go bad.  I need 4 DMOS FET model VN0116N5 or VN0120N5.  and then also need to replace 4 DMOS FET PN0116N5 or PN0120N5 that are probably near failure.  Total 8 pieces. Does anyone know where my friend can source these? Any help will be appreciated.

@holmz thanks. It looks like they have the VN but not PN.

Stephen thinks those VN transistors are not authentic.

It sounds like VN are gone but PN are not gone yet. I guess the VN's could be replaced and pray that it will play. Larger heatsinks are being put in.

They refused to work on it because it is so old. But the 200w of pure class A sounded very good. Spectral doesn’t make pure class A anymore.
