[Premium-Rx] RF-590 A12 Assy Schematic

[Mac]

Tom:  doubtful I can be of significant help, BUT  my 590 book is a bit 
odd i think, My A12 section on table 1. A12 Interface Connection list 
what seems to be all the various Connection points at least presumably 
so. Starting with J1 and running thru/ending J9-9..

Yet a few more pages at Table 2. indeed J10. is listed as a part and 
like your pictorial component layout page 13/14 Figure 3. there sits 
J10. in the upper left and above J6 and J5

I will add this book is a bit odd or different and lots i had not paid 
attention to so let me prowl thru more of it and sorta get myself up to 
a better speed and see if i can offer more help after a little more 
review please..

Best:  mac/mc  w5mc
