What are LDC Dunlab tubes? They were used in UP No. 80 (later 8080) an experimental coal-fired gas-turbine-electric locomotive that ran in the early 1960s. A Google search on Dunlab tubes was fruitless. hankmorris@earthlink.net |

A small amount of power applyed to the grid controls a large amount of power on the plate. Tubes like this were popular in motor control circuts. http://www.themachineryworks.com hgorin@ix.netcom.com |

Thanks, but the have something to do with gas flow. However, the article I was reading didn't go into any detail, preferring to assume that simply everybody knew what a Dunlab tube was. I hate to disappoint the author, but I know I don't. hankmorris@earthlink.net |
