[Test-Equipment] Re: Heath/NRI Ign. Scope

Unfortunately, I only have the instructions for use - I've never had 
the schematic or repair info, as I got this NRI Model 261 second-hand.  
I don't think it even came with such, due to being late-era "radio 
school" (automotive electronics, in this case.)  Even early NRI stuff 
is notorious for being difficult to find schematics for ... you'd think 
Heathkit wouldn't be, but this instrument is unusually rare.  I assume 
you've inquired at the usual sources: hi-manuals.com and manualman.com, 
etc.  Don't rely on the model number, BTW - my '81 Heath catalog shows 
it as CO-1015, while the fragment of manual I have calls it COA-1015-2. 
  Does either agree with your unit?  If you do a dogpile.com search on 
"Heathkit ignition scope"  you might find something - google, yahoo and 
msn are worse than useless for web searches.

You're welcome to what I have for the price of your mailing address.  I 
have no provision for scanning anything.
