Default INFINITY active crossover

Hello

This question following for audio technicians and all .

I got to repair this old INFINITY active crossover - ( model ? ) no any information on the web ... one channel no sound .

In the device there are 4 special transistors ( 2 for each channel ) - MSPF-772 - There is no information on the web... one of them is damage ( short ) .
When I change with the anther channel ... the sound appears.
It seems to be NPN with 2 diodes on C-E.....but it is not..... ?

Thanks for any help
( see the pictures on this address )
