" This was c. the same time that I found out that General
Electric Medical had cancelled a contract with Dick because he failed to fix
the problem of sudden 8877 failures in a MRI amplifier that he was
manufacturing for G. E."
As I recall, the "parasitic" problem with the Alpha amps occurred at exactly
the same time that Eimac made a batch of bad ceramic tubes (in particular,
the 8877). At the same time you were analyzing the problem, Eimac changed
the construction of the tube. I am still amazed that your analysis of the
parasitic problem in the Alpha amps resulted in reduced problems for Alpha
owners, even though Alpha did not implement your ideas.
