Grundig 6007 - Workshop Project #27

This one is a rather expensive piece of retro kit: A Grundig 6007 high voltage lab power supply. It is designed specifically for testing tube circuits and I was on the hunt for one for the longest time. They pop up every now and then but usually are either in complete disarray or extremely expensive. I found out later why... But since I really really wanted one, and my birthday was coming up, I treated myself! Well, there goes the rest of the tinkering budget for 2023; good thing I have some backlog.
