Good Morning,
I am working with the VM129 and have not found a 12 volt AC power supply for the relay system. Any tip on where I can find such a 12 Volt AC transformer powered by 110 volt US household? The idea one would be relatively small.
Thank you
If you kit supplier is unable to supply such a transformer, which is quite common, i’d recommend to look for a better supplier 
Radio Shack has several ranging from 300mA to 3.0A capacity…
Wow - thanks very much for the quick response. I’ll check with Radio Shack today.
