1ZH37B(1J37B) More data sheets
Sometimes different versions of a tube data sheet reveal different details. I have two loose data sheets that came with a ebay purchase of the 1ZH37B.
I scanned these sheets and performed OCR of the Cyrilic characters with ABBYY express software. The original print quality was poor, however enough words were recognized to produce a useable translation by uploading the OCR result to Google-Translate.
1zh37b_sheet.pdf two page scan with OCR Russian text
1zh37b_sheet_EN.pdf Google translate output with English text, but no pictures diminished formatting.
1zh37b_3pages.pdf three page scan with OCR Russian text
1zh37b_3pages_EN.pdf Google translate output with English text, but no pictures diminished formatting
The Google-Translate output is very difficult to save. So far, the only sucessful method I found is to print the output frame to a single very tall pdf page. The text can then be copied and pasted readily from this output. The two files above with EN in the file name have just the Google-translated English text.
