Customer Testimonials
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
