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.

I've had luck finding obsolete semis on eBay. Just do NOT buy from China as they are most likely fakes.

@chungjh if you only replace the bad ones (VN), then do you need the PN ?
 

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

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.

Stephen thinks those VN transistors are not authentic.

One of the datasheets to match parameters:

https://www.datasheets360.com/part/detail/vn0116n5/-2706982422070585151/

All other datasheets you can find same place for your further research.

Search transistors by datasheet is possible below:

After finding possible choices, you can use best available even if it's far not the best.
