Subject: [RTTY] Need Repair advice on ICE 419b Band pass Filters

Hi All

I have 2 - ICE 419b Band pass Filters for my small SO2R station. I have 
blown 2 of the filters in one of the boxes.  Both 20 and 10 meters show 
infinite SWR on the analyzer all other bands are ok.  I have been doing 
research on the net and cannot find a schematic anywhere, but have read a 
number of posts that say the capacitors blow easily.  I have done the sniff 
test and also cannot see any sign of damage.  I was wondering if anyone has 
a schematic and / or could advise me on where to start.

Thanks in advance
Ian, VE3JI
