Hey all! Can't believe where the time goes! I've been using these eq addons for four years now ! (Wow!)
I recently needed some more so decided to buy a batch of metal and pcbs for anyone that wanted to either upgrade their NV73 or build the full thing from scratch.. I've only ordered 20 extra.. but if there's interest, I can order more and keep them in stock like my other two 500 series products..
I wanted to keep the ability to use mustard caps (or remake mustard caps) like an original 1073 and the circuit is the same of course. There's 4 connections to make to the NV73. I’ll detail it in a little manual..
Anyway.. here she is! (knobs courtesy of the fantastic Don Audio store.. no relation!)
