Hubert,

What happened with the project to revive a 5061A with a 5030
physics package?

Thank you for your effort. The 5061A is not my problem. I' m in need for the
5030 diagrams. These are a real problem to find. My major problem is to know
the resistance of the heater thermistor at temperature. I do not know a
method to find this value, exept knowing the setresistor of the 5030.
Best regards,
Hubert
