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 ) http://dudulab.googlepages.com/infinity _________________ Dudu's-lab ISRAEL |
