Ian asked
"Laser 2 x CSI 25kW (was there a type number... Paul?)"
Sorry Ian, I only just saw this. I've been on my mobile only for about a week and the old mince-pies are getting tired!
The CSI transmitters were both T-25 (model number)
each with a single end 3CX20000 tube in the final.
They used only three bottles to drive it:
a 12BY7A as oscillator, a 6146 as a buffer,
then a 5CX1500A as the driver.
The line up was a pair of these for each station, with a combiner sat between them (Egyptian T).
The other side of the hall had provision for a further pair for the second service, but this didn't go ahead due to financial concerns by its backer.
