looking for 3AQP1 CRT

[Tom Chesek]

I don't have resources available to me here at work but if my memory is 
correct I think the Heathkit IO-101 Vectorscope uses the 3RP1A CRT and I've 
seen these scopes sell on eBay for $10-$20 on a regular basis. I don't 
currently see any there now but keep an eye out if this version of the 3RP1 
is acceptable. The HO-10 and HO-13 Heathkit scopes also use the 3RP1 but 
they sell for a good bit more than the vectorscopes.
