HarryO Posted January 10, 2010 Share Posted January 10, 2010 HELP, I need to convert a russian tube to US or Euro coding. the tube is marked 6H1(an upside down U) -B and a backwards N. It resembles a 6922 size. Any help would be appreciated. Harry Quote Link to comment Share on other sites More sharing options...
