some radar equipment

[moominza]

hey everyone.this is my first post.i got my hands on some radar equipment which I was led to believe are some of the first to be implemented in British air-force.what would you guess is the value of these.the valves also needs to go
a.i mk4, bc 455b,unit25 100/1016,R.F unit26

The valves look like mostly 807 beam tetrodes to me, but I would need better pictures to be able to verify this. Some better pictures of the other equipment, including close up shots of the data plates would also help.

1) is part of an RAF AI (Aircraft Identification) Radar setup
2) is part of a late-WW2 US radio set SCR-274-N
3) and 4) are part of the GEE setup
5) The valves are exactly what you have written. A VT83 full-wave rectifier, a VU111 half-wave rectifier and a load of 807s. The 807 was famously used in the Wireless Set No 19 as the final power amplifier for it's transmitter.

ATS25 is the British Army name for an 807 (It means Army Transmitting Screen-Grid Tetrode 25).
