Hi Having said the LM9022 VFD filament/HV driver chip had gone unobtainium, I've found it back in stock with RS Components in the UK at about the same price that it was when I last bought them from Farnell. Anyone experimenting with VFDs might find this an interesting chip. I use it in my

That is what I remember hearing. I offered them tubes on their list and a lead on the trigger tubes they needed - got the intial discussion and then nothing. At that stage the message was that they needed a whole complement of tubes. BUT, they must actually have had the bulk of them already

Just happened across a NOS 5BP1 green phosphor CRT. Still in the original military marked cardboard carton, never removed, one end of the carton unstapled, but the CRT is still secured in the box. I no longer have a CRT tester so can't test this beast. Any interest? Terry -- You received this
