The valve line-up as it was when I acquired the wireless was:

5Z4G (HT rec)
VR65 (audio preamp?)
EL33 (audio output)
6SK7 metal clad (if amp)
6SK8 metal clad (mixer/osc)
6SK7G (RF preamp)

Interesting mixture, but after WW2 there were lots of surplus valves around. I have no way to be sure they are all the original valves, but the above is how it was when I got it.

The set is fully functional now, except for the magic eye which is working but the phosphor is badly burned. I have obtained a modern (Russian?) close equivalent but fitting that needs a slight circuit mod which I have not decided to do. The original works well enough.
