That's not to say you can't or shouldn't buy our cutters from international sources. We sell all over the world to service the global marketplace. However, it is unlikely an authorized distributor would import cutters into their home country and ship them back to the US for an extremely low price. > That doesn't directly prove their origin. My old Plato cutters have a made in U.S.A printed in them. I haven't seen one picture of the new pliers that say this and no mention from the manufacturer that they still are (they used to advertise them as such). Where they're shipped from isn't proof. If Techspray gets a container of them from the Far East, they can get them into their distribution network just as easily and at less cost than they could likely make them.   > I sent them an email and will report back when I get a reply.   I heard back from Techspray, and they are no longer made in the U.S. They are now made in Costa Rica.

So we have the computer in a docking station at one location with connection via an USB-C, and at home just on a power cord and wifi. That's a lot of connecting and unconnecting on the USB-C. Figure 200 plus work days in the office with an insertion/outsertion cycle daily; i wonder when they will get flakey.   You don't want to find out - it will invariably mean lost data.   Keeping them clean is of top importance. Once dust, grit or grease gets into the equation, replacement may be the only reliable option.   Ratings for power connectors have reduced insertion counts because they involve monitored voltage drops at high current. Obviously, use at less current or for shorter time periods will mask their reduced ability for cntinuous rated use. As long as it doesn't burn before the toast pops, you're satisfied.   Signal connections are a different story and require different materials and test methods. Again, as long as the pins you need work, while you're using them, you're happy.   Combined signal and power (ie USB) are a can of worms, though often only one function may be required of a multipurpose connection at one time.   RL

As mentioned, it is the Elenco S-1325. To my surprise, it apparently is still being made but who knows for how long. Just a curiosity more than anything else. Certainly seems clean enough.   Thanks once again guys.

Me too, in the early 1960s, but it was from 2nd hand bits, especially the VCR97 CRT. And definitely not calibrated! I still have it, and it works just as badly as originally...

If your RMS meter shows abot 120 volts AC out of >the wall socket a scope will show around 170 volts peak.   My signal generator is an all valve (four) unit and it works from 5 Hz to 600 KHz.
