For one thing the transmitters that used these tubes were mostly used in
fixed communications sites. Or in Shelters that were placed at some location and did not move often. 250th tubes were shipped in containers that had springs suspending them with in a frame. Some tubes were shipped in containers using a frame made of card board or wood and the tubes were suspended by fabric straps. While these more or less stationary transmitters may have used vertically mounted 250th, 100th, 4-400A and such the mobile transmitters used 211, 813, 811, 807/1625 or 4X150 tubes which can take the vibration and operate in other positions other than vertical. 73 Bill wa4lav At 11:32 AM 8/25/2004 -0400, jsb@digistar.com wrote: On Wed, 25 Aug 2004, Bill Fuqua wrote:
