I know it's a long-shot, but I'm looking for a replacement CRT for the HAL ST-6000 RTTY decoder. The CRT is a 1-inch Brimar D3-130GH. The usual on-line sources haven't turned up anything and after researching alternatives, adapting the CRT won't be trivial. A photo appears in the link below. http://www.r-type.org/hireshtm/xaai0310b.htm Thanks. Paul, W9AC
