Thanks Peter. In the interests of balance though, it is worth pointing out this tube has been restored/boosted on my Radar tester and is in fact slightly soft. Certainly, not as pin-sharp as Trevor's (MurphyV310) recently discovered tube. However I now have another TV24A donor set. Who knows what its tube will prove to be like?

Back to topic. Here are two views of the HMV 907 from 1938. The colour photo pre-dates digital and shows the example I used to own.
