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.

… that are probably near failure …

I doubt it. Fighter planes and spaceships run this gear, and they either work or fail.
(Sometimes it is possible to have them go bad in a non binary way.)

Did you try “GTS” (Aussie slang for “Google that $hit”)?

First, google those part numbers. You might find the parts right away. Then check Jameson Electronics on the West coast. Then ask the Spectral designer if he’s still alive or anyone associated with the company. Then ask Nelson Pass. I hope you’ve consulted Bill Thalmann in Springfield, VA, to do the work.

@lewm  or the OP could just get them from the first link that showed up?
