Mindblowing JT3D/TF33 recordings from powerun on E3A

I received the engine sound recordings from a JT3D/TF33 power run: MIND BLOWING 🙂 various power settings from IDLE to up to 97% with synchronized engines all in excellent quality recorded inside the cabin behind the cockpit (hence no background noises). This will allow me to create a highly realistic engine sound module for the 707 simulator.
Many thanks to the person(s) involved. This is really a milestone in the project. Here are some extracts.
