RoHS also addresses this, the manufacturers have to take back
old equipment and dispose of it properly.

That's already well past the lifetime of most consumer electronics.

Hi all,
Yes some T&E is exempt. Not all batteries are, mercury cells were banned
about 10 years ago. This was a great pity as they make great voltage
references!
Hg is allowed in lamps, lead in ceramics and Cd in light dependant
resistors.
I don't know who will enforce it, I can't see trading stand

The trick is to use a tuna can instead of a soup can and coopt one of the

In addition to the other points made, there is also theoretical calculations.
The cesium fountain travels at a known dispersion of speeds (source of error)
as well as known potential error in the tuning methods, so it's possible to
estimate that the new design will have a lower error without act
Christopher,
Back in January of this year I purchased a 5061A from Test Equipment
Surplus (Mr. Joon Kyong). It was defective and I sent it back,
expecting a prompt refund. However, no amount of begging and pleading
had any effect until I left negative feedback. He responded that very
day!
Hola Jose,
Well, I have uploaded the 5370A manual of 42MB last October to David's site,
and it seems to be still there:

(circuit diagrams are stitched for plotting on A1/A0 plotter.)
There's a picture on p. 252 (8-93) of this 'A' unit, 3 PCB spares

I got my money back today less a few dollars (!?!?!) and a ~$20 PayPal

initiated an eBay dispute on the item. It had absolutely no effect.
The kicker seemingly was declaring that I would proceed with criminal
