[Premium-Rx] RF-590 A12 Assy Schematic

[Mac]

Tom upon further review my 'odd'  book is so jacked up, coupled with a 
failing memory,  this book appears to be maybe complete, but, not in any 
order.

My guess is i took it apart to make a copy for someone and had all the 
fold out drawings/schematics pulled to run at one effort for that size 
paper, as well had removed all the tab or index dividers and likely it 
was on the "Mac" work table, often in most homes called the family 
dining room table.

Then i must presume after my guess, an unreasonable period [my guess 4-6 
weeks] of time to my significant other {wife} issued a plea that i 
likely ignored then morphed into a demand or most often just a "look"  
there again i likely ignored, assuming my BS would carry me another 2-3 
weeks before some real action would be required.

Oh but then to one day find the binder papers tabs and such placed here 
in my radio room in my chair, in no order and with not a lot of love or 
concern seemingly given to the gathering or placement here in my office, 
my assumption is we had some guest coming and i had over played my hand 
[again] and she [my wife] took out some anger/frustrations and with an 
indifferent attitude dumped it here, and was damn glad to see it OFF the 
dining room table. 43 years together still only buys or allows you so 
much latitude it seems.

So my result is for me to really dig into this book i will need to 
reassert my claim for the Mac worktable and spread it all out again and 
try and put this puppy back together again, wherein i might be able to 
offer you more help.

In this heap however i did also find the factory acceptance test of the 
time for the 590 receivers and for s/n. 1881 in particular
