need help with power transistor

slackama · 24th December 2009, 07:47 PM

I have a 1980 realistic model sta 95 which is blowing the main fuse i tracked it down to the power transistor on one channel > its shorted out , the only data on the cap is D 732 e8g to-3 mount style would like to cross ref. and replace with new if possible ? any help would be appreciated

thanks Dave

2SD732 from Sanyo.. long obsolete. The best thing to do would be to replace all the TO-3 devices with MJL21193/4.
