These old tubes will often show a shiny, mirror-like splash on the inside of the glass envelope. And yes, they can generate a copius amount of x-rays with only a modest (10 - 15 KV) high voltage. By the mid-1920's though most tube manufactures had discovered cheaper, and easier to apply getter materials which incidentally had lower atomic numbers such as Barium. By their nature, these tubes don't hold a candle (so to speak) to the earlier tubes for the production of X-rays.<br /><br />Bruce - KK0SBruce Barleynoreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-54570499405012434682009-06-05T10:13:44.258-04:002009-06-05T10:13:44.258-04:00Methinks Alan received one too many jolts from his...Methinks Alan received one too many jolts from his cute 'do.<br /><br />And the Honor House Ad......I get that same look after a wild night of rosin snorting :-).<br /><br />73 from Oxnard, Steve Smith WB6TNLSteve "Snort Rosin" Smith WB6TNLhttps://www.blogger.com/profile/01570621886789949035noreply@blogger.com
