Dual Triode valve/tubes in push-pull circuitry

Hi,



This is my first post, apologies if I have placed this question in the incorrect section.



I have an interest in buying the 6386 Valves. However I have a more general question about dual triode valves in general which is basically...



What makes these dual triode remote cut-off valves ideally suited to push pull compressor types?


I know it sounds a bit specific but I saw this mentioned in an article about the history of audio processing and want to know why they are ideally suited...



If anyone could shed some light on this particular query it would be of great help as searching for a relevant answer on the internet is a bit of a minefield.



Thanks
