I put together a pretty simple load box with a line out for silent recording. This circuit will apply a resistive based load to safely discharge a tube amp via the speaker output. Then you can run a 1/4" cable into an interface.

4 ohm 50W resistors should be Vishay Dale type RH-50-4.0 or equivalent (Mouser part number 71-RH-50-4.0)
