Maury Zivitz, Ph.D.
(Dr. Zee)
With 50 years experience in electronics design, repair, and restoration my goal is to make the following
gear work better than new: radios, car radios, phonographs, stereo amplifiers, guitar amplifiers, wire
recorders, 16-mm motion picture projectors with sound and “you name it.” I service tube and transistor
circuits. [Proprietary integrated circuits (IC’s) can be problematic to replace.] Cabinet restoration services
are not yet available. My current focus is electronic functionality.
Welcome to commerce in America. [Ha!] By no means in the last paragraph did I really mean 50 years of
full-time experience in electronic design and repair. Nine of those years, however, were spent at Texas
Instruments, Inc. (T.I.) in Houston, TX.
After working at T.I. initially in Process Control, I worked as their chief circuit troubleshooter for the 64-K
DRAM memory chip. I “chased” control signals on that memory chip for nearly 5 years! They call that
work done with the aid of microscope, “Internal probe.” That effort requires a steady hand and a natural
curiosity. Thereby I identified the root cause of various timing-chain issues. Next, I characterized softerror rates of that same memory chip by bombarding it with Alpha rays. Last, I developed an Expert
System to identify at which photo-mask level a particulate defect had occurred during manufacture of that
memory chip.
Next I spent 28.5 years at Roche Diagnostics, Inc. mostly here in Indianapolis. After two years of optical
and electronic (op-amp) design work, in Houston, I came here to start a math and optics Department.
Along the way I supervised a UHF research endeavor.
In my hometown of Mobile, Alabama in 1957 I hooked my 1N34A germanium crystal set to the finger stop
on a rotary dial, black, Bakelite telephone. That was a great antenna!
When I lived in Houston, I operated “Dr. Zee’s OLD RADIO HOSPITAL” for a half dozen years. I
certainly know the art of making people pleased with my repair and restoration services.
Along the way, I got a doctorate in Solid-State Physics and a postdoctoral fellowship in Atomic Collisions.
So when I say, “It’s fixed,” then doggone it — it’s fixed!
