A quick introduction to the amps wich power the main system.
These are some impressive amplifiers!
Built by Hans Fontain.
A massive 4 chassis affair with separate mercury vapour rectified power supplies.
Both the driver and output tube can be easily swapped. Everything mounted on modules.
Big transmitting tubes. Including the gargantuan GM100.
Here a video of the main system paying between two lectures. With some footage of Hans' amps (not playing during this video).
Thanks a lot to Hans for brining these behemoths to Bellême.
