Also interesting: it's not ROHS (has lead, mercury, cadmium, Cr4,
PBB's, and PBDE's) and uses old-fashioned AC votage jumpering, ie it
has a power transformer.

John -- for your own instruments, at one time weren't you planning to
use those switching wall-warts with the various "slide-on" plugs for internationalization? Did you ever end up doing that?

We have one benchtop delay generator that uses 24 volt DC input, and
we furnish an external switching supply, the kind like printers use.

We are also doing a series of smaller boxes that look like

that use 12 volts, and we supply a true wart, a universal switcher
that has interchangable plug adapters for different countries.
Phihong, I think.

Lately we avoid running AC into a box if we can help it. Everybody
seems used to external adapters thses days. Besides, they don't find
out until after they've bought it!

One of our newish Tek scopes has an external supply.

John



the old TEK 555 and 556 scopes had externals supplies,too! Big 'uns.

The dual beams? That's what the bottom shelf of the cart was for!


I always thought that was for the crate of beer.
