A bit late, I had forgotton these things are open collector outputs too, and thought my device was dead until I noticed about 100 mv of hum on the baseline with my pocket knife covering it. Duh, so spent around 1.5 hours digging thru a quart bag of rat shack 1/4 watt resistors to locate some 390 ohm-ers, paste them on the terminal board, at which time the first one worked a treat. Nice almost rail to rail switch. It is rated to sink 25 mills, and the 390 ohm will be in the middle of the 12-13 mill bracket, with 5 volts to play with. So the 2nd one is under clamp until 8 or 9 this evening. My Go-2 is like me, getting old & slow. Too bad I have learned superglue is not all that trustworthy. OTOH, I had used it to mount the A/B units, and had to use a pair of pliers to twist them loose. Same alu alloy & freshly machined, go figure. And I think I left the iron plugged in. Again... Sigh. Time to see what the missus wants for dinner, as soon as I go unplug that 60 yo Weller WTCP. The original model that looked like a black brick. Well north of 100,000 hot hours by now and is still on the original heater element. > > Cheers, Gene Heskett Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
