[sdiy] Looking for wisdom - Klein & Hummel UE-100

[mark verbos]

Hello,

My brother-in-law just gave me a Klein & Hummel UE-100 tube equalizer that was found in a dumpster next to Danish National Radio 20 years ago. Since then it sat in his brother’s basement. I have a bunch of questions that I am hoping somebody here can answer. First, what are these connectors? Tuchel? Pinout? Second, how should I power this up safely? I assume that the power caps are dead, but any advice? I have read about people powering these and caps exploding, is there any way to prevent that? If I replace these 16uF electrolytics, the trimming is gonna be out, there appears to be just a few trims, so they can’t be for all these caps. 

The build quality of this is amazing. It weighs a ton.
