[sdiy] Negistor article, Popular Electronics, Dec. 1975

[Fernando de Izuzquiza]

Hi,

The figures on the P-E, dec 75 "The Misterious Negistor" scanned  
article available the net are not very legible.

Does someone on the list have the original magazine issue and can  
scan the figures please?

Thank you,

Fernando

P.S.: btw, I've read somewhere that using TO-18 (metal can) 2N2222/A  
was necessary since normal TO-92 ones didn't work (were not behaving  
as a negistor) Do someone confirm this fact?
