I'm so pumped I found this series. I have a Junior that i'm restoring. Mine is the D/1, and it's so old it doesn't have a date on the electronics box. I've just replaced the pressostat because my boiler valve was blowing like you describe in the video. Next step is dismantling and fixing the frame (it's very rusted). My main power switch also melted, so I'm trying to source a replacement for it. Any tips on sourcing replacement? Also, if the vibe pump is still working, is it worth replacing while I have the whole thing dismantled?
