Precision Radiation Instruments Model 107

[TimR]

Hello all,

I wonder of anyone out there is using one of the old Precision Radiation Instruments Model 107C's (more for hobbies than professionally of course). I have one of these  and was was wondered if anyone had converted them to use more common power source than the required mix of two 1.5 volt, one 45 volt and one 67.5 volt batteries. Alternatively, if someone can think of better place for such a question I would be pleased to hear it.

Thanks all.
