[JRC] JST-245

[Tony Faiola]

Hello:

After searching around, I found my full JST-245 Service manual.  The 
operational manual didn't have the major schematics in it, however it 
did have block diagrams with interconnections and some detailed 
schematics.  

The operational manual did not have the power supply schematics, however 
the maintenance manual does have the complete power supply schematics 
indicating all the components, test points, etc.

This power supply would be very difficult to troubleshoot without this 
manual.  Some of the parts called out in the parts list are available 
from various sources such as NTE, Mouser, Jameco, etc.  Other parts 
might be a procurement challenge, but looking at the circuits, a pro 
technician might get it going.  I just finished with an IFR 1200S, and 
similar situation - the service manual is a must, and without a card 
extender, one has to use a shot gun approach to repair and troubleshoot!

Ciao, Tony, K3WX
