  1. Hi Limor, I wonder if I can get a copy of the whole document that came with the tubes. I kinda like vacuum tubes since I grew up with them. Many thanks and I look forward to getting my Ice Tube kits.

    If you need help with the translation, please let me know.


  5. Howdy Anton, You must speak Russian ? Yes it would be interesting to translate so I would like your help. I also have a Russian that has e mailed me and needs a certain type searchcoil from my store. I might have to recruit you to tell me exactly what he is looking for. Thank you Anton and be safe.
