[R-390] Trouble shooting procedure

[Flowertime01 at wmconnect.com]

Fellows,

One of you spent some time putting together a trouble shooting procedure and 
mailed it to me and ask me to comment. 

I think the document starts as follows.
But I may be wrong.

I will admit the following but my story may change.
I forgot who sent it to me.
I forgot what was sent and I am trying to find it on my computer.

Will someone please tell me who to send this back to?
If I have the wrong file will you please send me a new copy.

I do want to continue with this project and get it done.

I am sorry I have let if go this long.

R390A not working at all:   Roger AI4NI 

While waiting for your copy of the Y2K manual to down load so you have some 
schematics to work with you can start with the eye balls.

The old school house mantra was that receiver worked yesterday. Today it does 
not work there for it has one and only one problem. Method one is eyeball the 
problem to one stage and fix it. Method two was listen to it and isolate it 
to one stage and fix it.

You eyeballed a dead receiver first because most days a tube had died. Next 
was a loose subassembly connector or a broken wire some where on the front 
panel. 50 years later here we have added failed capacitors to the short list. (pun 
there intended). Eyeballing got you past the tubes not being lit.
