[TenTec] Matched PSU to Orions

[Petr Ourednik]

Hi folks,

I am interesting in which kind of genuine PSU unit is matched to Orion transceivers?
I investigated around and found that Model 940 - Switching Power Supply / Speaker Console, 25 amp 
looks like it fits to Orions physicaly but is there some PSU which is designed to make Orion line
together with Model 307B speaker box together i.e.?

Thanks,
