 Waht, even in CRTs?

 In the UK, the electrodes of a pentode -- a signal ampiifying valve  are :
  cathode, control grid, screen grid, supressor
grid, anode.

 But for a CRT they're cathode, (control) grid, first anod, second (or
 focus) anode, somethimes third anode and final anode.

 Are you seriously saying that in Germany, the focus electrode in a  CRT is
  called a 'supressor grid'?  
 Are you sure you two aren't talking at cross purposes?  The biggest
 difference between UK and US English here is probably Tube (US) = Valve
 (UK).  The usual German word for a thermionic valve, die Rohre,
 literally means "reed", and I think it is also used for "tube" or
 "pipe"
 in a lot of other contexts.

In German, a vacuum tube or valve is called "eine R?hre" (or "Roehre"
for
those without umlauts), a pipe or other kind of tube is called "ein Rohr",
"(das Rohr)" AFAIK.

"?" is pronounced like "er" BTW.
