Currently doing some work with a friends metal detector(I might build one for myself too) and needed to change out an op amp. I found this handy dandy cross reference to Heathkit parts and thought I'd share.

 

Thanks Kermit2,

I have some old heath Kit stuff, might need that sometime.

Wish I could find a cross for some Zenith transistors I have. Ask Zenith on line once and they wanted $15.00 for a tech to help me. Go figure.

 

Thanks Kermit2, much appreciated
