Hi, I have an IO-4555 Heathkit O-Scope that started spewing out smoke
15 seconds after turning it on.

Would like to find someone that can shoot me a PDF of the assembly
manual with schematics. The operations manual would be nice also.

I've checked Google and Dogpile for variations and can only find a
schematic for the dual trace version. (IO-4550)

A few places are selling the manuals for a goofy amount of money. I
may have some files, templates, webspace, etc. that I can offer for
trade.

Also, have you asked on the Yahoo Heathkit mailing list?

BTW, has anyone kept up with the Heathkit/BAMA fiasco? It sure makes
acquiring Heath products without manuals a bad deal.
