Hi to all,
Hi Bandersen,

Your best chance to find a 405 line test generator would be to place a request on the UK Vintage (UKVRR) "Wanted" section.

Tube-type generators were in full swing from the 50s/60s, OK, 405 started in 1936. 625 (BBC2) started in 1964 so 405 started waning. First generation color sets (1967-1970) were dual standard but complicated and not very reliable.
When BBC1 & ITV were duplicated on 625/color/UHF, TVs became single standard and only shops who had been in TV repair for 20/30 years still had 405 test gear.
405 was finally switched off in 1983.

With a bit of luck, an old 405 generator might have an external video input to use it as a System A Modulator.

An interesting thread on another UK TV forum about a 405 video generator using a PIC microchip.
