Question about instrument voltage regulator

Did you get the new regulator in a parts store or did you have to special order it from somewhere? 63 Valiant having the same issues


I got mine from Real Time Engineering, http://rt-eng.com/mediawiki/index.php/RTE_limiter . Looked just like the original and it's not suppose to over voltage if there is a bad ground. Plugged right in place of the original one.
