Anton vs. Electro Nuetronics
I am new to the hobby of collecting hot rocks (I recognize a few of
your names from ebay) and I recently purchased a CDV-700 model 6 by
Anton that worked great for the first few days and was working fine
the last time I used it. The next time I turned it on it was dead,
no needle movement at all, however I could hear the 'clicking' in
the headset as the probe was held near a radioactive source it was
very faint however, barely audible. I tried replacing the batteries
and still nothing except the faint clicking in the headset.
I have since purchased a model 6b by Electro Nuetronics that has not
arrived yet and was wondering how the two compare and if there are
any differences that are worth noting.
- Hi, Steve,
Hey, you should have bought the Anton Model 5 which I recently sold
on eBay :-) It worked fine, and had a HOT test source! My Anton had
a great meter movement when tested with a radioactive source, smooth
and not erratic at all. Only disadvantage is it took 5 batteries.
Test the things Silvermoon recommended, and don't rule out the meter
itself. I had a dead meter on a CDV-717. Replaced it and got meter
movement on battery test. Now if there were only a nearby nuclear
detonation, so I could test the ion chamber :-)

Maybe E-N's worked better 40 years ago. Im happy with my victoreen 700 model
6A. Its worked really well and even had a anton halogen tube in it replacing
the old one. Did landers,frey and clarke make 700? and what About a chatham
700? wonder how those rank on the list...
btw, i am hoping to get a more sensitive meter to replace the 700 for
collecting. know any good ones?
- Hi Steve!
Welcome aboard! Sorry to hear that your Anton has problems, and that
you've actually bought an E-N... I'd opt for repairing the Anton. The E-N
counter is very poorly engineered, and will need extensive modification
before it can hope to possibly work for more than five seconds, let alone
reliably. The repairs I'm made to E-N's are listed in the archives. The HV
B+ isn't regulated either well or at all, plus the pulses from the GM tube
regularly blow the transistors in the metering circuit...
I was blessed with a new, in the box E-N: It ran for five seconds before
conking out. Good thing I'm not depending on it!
The Anton is hopeful: The HV section is working, vis a vis the faint
clicks. The problem is in the metering circuit. You may have blown a
Most folks prefer the Lionel, then Victoreen in that order, and Anton then
E-N dead last.
The hobby of things radioactive is fun! I'm blessed with living near a
source of super high grade Pitchblende, Samarskite, and various yellow
