I had a great opportunity to repair gorgeous EMT140 plate reverb! It had problem with pickup low output (photo 3,4) and leaky snubber capacitors in motor block (photo 5). Otherwise, it’s aligned very well. Thanks to Андрей Лифенко (Andrei Lifenco) !

Please, meet this very promising startup of Audio Construction Bureau - there is production of CK12 capsule, which I'm involved too. The goal is to produce extremely accurate replica of the famous CK12. Each part is thoroughly engineered with all patience needed for such work.
