First of all, thank you so much for providing these incredible kits, you are a worldwide treasure!
My question is a little long, I will try to be succinct. I built the buffer kit for a pair of DuKane branded Dixson meters. I fitted them with jumpers, as the Dixson meters have internal rectifiers. In order to test the setup, I hooked the meters up to the buffer without lamps (I did sort of poke the lamp leads through on one side, just to make sure they lit up, and all seemed well), and used a 12v wall wart to provide power. I calibrated the meters, sorta, and all looked well. One issue was that one of the meter's ballistics was different than the other, slightly, and this meter also did not return to zero.
I powered down and fitted the VU2 buffer into my prototype chassis. I had a purchased an International Power power supply... WAAAYYY overkill, at 1.7 amps of output power. I setup the power supply and applied power to test, and saw 12V at the output. Then I hooked up meters and lamps and turned everything on... and the 10R resistor on the Left side, for the lamps, just lit up!!! yikes!
Any thoughts? Is that power supply to much? Thanks so much for your kits, and this great build thread, I appreciate everything you do!
