[TA-A] Re: Pan AG-1960 Power Supply

With the fuse blowing it tells me that that STRD is bad and check caps., 
diodes. Also, check all resistors to make sure they are OK. I use to get most 
of my parts for these from Parts from MCM or a few others. MCM used to have 
complete supplies also and maybe a manual. I think they are a Panasonic 
distributor, I know they carry many of their parts. Some of these STRDs. are 
expensive so, make sure you have no shorts or open components before turning 
on. Also, if this unit was power surged, there is a good chance that one or 
both of larger supply caps. by main fuse are bad. Wish I had this unit in front 
of me. It takes longer to write than to fix.James Daly
