Title: ballast tubes number decoding, catalogs, ID Post by: Opcom on January 22, 2012, 01:25:07 AM I have a crate of 7H-10 tubes, and maybe some others. The part number looks like a 700mA tube with a 1-2V drop, but part numbers are not always decode-able or specs obvious. No telling what the "H" means.

Amperite still makes many types but does not give specs for them. They provide a "datasheet" but it is only a couple pages of general info and a part number list. I sent mail to Amperite asking for any copy of a handbook or comprehensive datasheet, decoding info, etc. Does anyone know where there is an online catalog or handbook for the ballast tubes? |
