I was wondering if someone might help me out. I have a hickok 533a tester and I have just acquired some old tubes from the 1920's and 30's and the tube numbers are not on my scroll. Would anyone know if there is some sort of a conversion chart so that I can test on my hickok? Any help is greatly appreciated. Bruce

Hi
If you have very early tubes drop the prefix. Tubes like UX280 and CX380 are actually 80's.
